  Mr. Justice Marshall
  delivered the opinion of the Court.
  This case presents an appeal from a decision of the Arizona Supreme Court upholding an Arizona statute requiring a year's residence in a county as a condition to receiving nonemergency hospitalization or medical care at the county's expense. The constitutional question presented is whether this durational residence requirement is repugnant to the Equal Protection Clause as applied by this Court in Shapiro v. Thompson, 394 U. S. 618 (1969).
  I
  Appellant Henry Evaro is an indigent suffering from a chronic asthmatic and bronchial illness. In early June 1971, Mr. Evaro moved from New Mexico to Phoenix in Maricopa County, Arizona. On July 8, 1971, Evaro had a severe respiratory attack and was sent by his attending physician to appellant Memorial Hospital, a nonprofit private community hospital. Pursuant to the Arizona statute governing medical care for indigents, Memorial notified the Maricopa County Board of Supervisors that it had in its charge an indigent who might qualify for county care and requested that Evaro be transferred to the County’s public hospital facility. In accordance with the approved procedures, Memorial also claimed reimbursement from the County in the amount of $1,202.60, for the care and services it had provided Evaro.
  Under Arizona law, the individual county governments are charged with the mandatory duty of providing.necessary hospital and medical care for their indigent sick. But the statute requires an indigent to have been a resident of the County for the preceding 12 months in order to be eligible for free nonemergency medical care. Maricopa County refused to admit Evaro to its public hospital or to reimburse Memorial solely because Evaro had not been a resident of the County for the preceding year. Appellees do not dispute that Evaro is an indigent or that he is a bona fide resident of Maricopa County.
  This action was instituted to determine whether appellee Maricopa County was obligated to provide medical care for Evaro or was liable to Memorial for the costs it incurred because of the County’s refusal to do so. This controversy necessarily requires an adjudication of the constitutionality of the Arizona dura-tional residence requirement for providing free medical care to indigents.
  The trial court held the residence requirement unconstitutional as a violation of the Equal Protection Clause. In a prior three-judge federal court suit against Pinal County, Arizona, the District Court had also declared the residence requirement unconstitutional and had enjoined its future application in Pinal County. Valenciano v. Bateman, 323 F. Supp. 600 (Ariz. 1971). Nonetheless, the Arizona Supreme Court upheld the challenged requirement. To resolve this conflict between a federal court and the highest court of the State, we noted probable jurisdiction, 410 U. S. 981 (1973), and we reverse the judgment of the Arizona Supreme Court.
  II
  In determining whether the challenged durational residence provision violates the Equal Protection Clause, we must first determine what burden of justification the classification created thereby must meet, by looking to the nature of the classification and the individual interests affected. The Court considered similar durational residence requirements for welfare assistance in Shapiro v. Thompson, 394 U. S. 618 (1969). The Court observed that those requirements created two classes of needy residents “indistinguishable from each other except that one is composed of residents who have resided a year or more, and the second of residents who have resided less than a year, in the jurisdiction. On the basis of this sole difference the first class [was] granted and second class [was] denied welfare aid upon which may depend the ability .. . to obtain the very means to subsist — food, shelter, and other necessities of life.” Id., at 627. The Court found that because this classification impinged on the constitutionally guaranteed right of interstate travel, it was to be judged by the standard of whether it promoted a compelling state interest. Finding such an interest wanting, the Court held the challenged residence requirements unconstitutional.
  Appellees argue that the residence requirement before us is distinguishable from those in Shapiro, while appellants urge that Shapiro is controlling. We agree with appellants that Arizona’s durational residence requirement for free medical care must be justified by a compelling state interest and that, such interests being lacking, the requirement is unconstitutional.
  Ill
  The right of interstate travel has repeatedly been recognized as a basic constitutional freedom. Whatever its ultimate scope, however, the right to travel was involved in only a limited sense in Shapiro. The Court was there concerned only with the right to migrate, “with intent to settle and abide” or, as the Court put it, “to migrate, resettle, find a new job, and start a new life.” Id., at 629. Even a bona fide residence requirement would burden the right to travel, if travel meant merely movement. But, in Shapiro, the Court explained that “[t]he residence requirement and the one-year waiting-period requirement are distinct and independent prerequisites” for assistance and only the latter was held to be unconstitutional. Id., at 636. Later, in invalidating a durational residence requirement for voter registration on the basis of Shapiro, we cautioned that our decision was not intended to “cast doubt on the validity of appropriately defined and uniformly applied bona fide residence requirements.” Dunn v. Blumstein, 405 U. S. 330, 342 n. 13 (1972).
  IV
  The appellees argue that the instant county residence requirement is distinguishable from the state residence requirements in Shapiro, in that the former penalizes, not interstate, but rather intrastate, travel. Even were we to draw a constitutional distinction between interstate and intrastate travel, a question we do not now consider, such a distinction would not support the judgment of the Arizona court in the case before us. Appellant Evaro has been effectively penalized for his interstate migration, although this was accomplished under the guise of a county residence requirement. What would be unconstitutional if done directly by the State can no more readily be accomplished by a county at the State’s direction. The Arizona Supreme Court could have construed the waiting-period requirements to apply to intrastate but not interstate migrants; but it did not do so, and “it is not our function to construe a state statute contrary to the construction given it by the highest court of a State.” O’Brien v. Skinner, 414 U. S. 524, 531 (1974).
  V
  Although any durational residence requirement impinges to some extent on the right to travel, the Court in Shapiro did not declare such a requirement to be per se unconstitutional. The Court’s holding was conditioned, 394 U. S., at 638 n. 21, by the caveat that some “waiting-period or residence requirements... may not be penalties upon the exercise of the constitutional right of interstate travel.” The amount of impact required to give rise to the compelling-state-interest test was not made clear. The Court spoke of the requisite impact in two ways. First, we considered whether the waiting period would deter migration:
  “An indigent who desires to migrate . . . will doubtless hesitate if he knows that he must risk making the move without the possibility of falling back on state welfare assistance during his first year of residence, when his need may be most acute.” Id., at 629.
  Second, the Court considered the extent to which the residence requirement served to penalize the exercise of the right to travel.
  The appellees here argue that the denial of non-emergency medical care, unlike the denial of welfare, is not apt to deter migration; but it is far from clear that the challenged statute is unlikely to have any deterrent effect. A person afflicted with a serious respiratory ailment, particularly an indigent whose efforts to provide a living for his family have been inhibited by his incapacitating illness, might well think of migrating to the clean dry air of Arizona, where relief from his disease could also bring relief from unemployment and poverty. But he may hesitate if he knows that he must make the move without the possibility of falling back on the State for medical care should his condition still plague him or grow more severe during his first year of residence.
  It is true, as appellees argue, that there is no evidence in the record before us that anyone was actually deterred from traveling by the challenged restriction. But neither did the majority in Shapiro find any reason “to dispute the 'evidence that few welfare recipients have in fact been deterred [from moving] by residence requirements.’ Indeed, none of the litigants had themselves been deterred.” Dunn, 405 U. S., at 340 (citations omitted). An attempt to distinguish Shapiro by urging that a durational residence requirement for voter registration did not deter travel, was found to be a “fundamental misunderstanding of the law” in Dunn, supra, at 339-340:
  “Shapiro did not rest upon a finding that denial of welfare actually deterred travel. Nor have other 'right to travel’ cases in this Court always relied on the presence of actual deterrence. In Shapiro we explicitly stated that the compelling-state-interest test would be triggered by 'any classification which serves to penalize the exercise of that right [to travel] ....’” (Emphasis in original; footnote omitted.)
  Thus, Shapiro and Dunn stand for the proposition that a classification which “operates to penalize those persons . . . who have exercised their constitutional right of interstate migration,” must be justified by a compelling state interest. Oregon v. Mitchell, 400 U. S. 112, 238 (1970) (separate opinion of Brennan, White, and Marshall, JJ.) (emphasis added). Although any durational residence requirement imposes a potential cost on migration, the Court in Shapiro cautioned that some “waiting-period.[s] . . . may not be penalties.” 394 U. S., at 638 n. 21. In Dunn v. Blumstein, supra, the Court found that the denial of the franchise, “a fundamental political right,” Reynolds v. Sims, 377 U. S. 533, 562 (1964), was a penalty requiring application of the compelling-state-interest test. In Shapiro, the Court found denial of the basic “necessities of life” to be a penalty. Nonetheless, the Court has declined to strike down state statutes requiring one year of residence as a condition to lower tuition at state institutions of higher education.
  Whatever the ultimate parameters of the Shapiro penalty analysis, it is at least clear that medical care is as much “a basic necessity of life” to an indigent as welfare assistance. And, governmental privileges or benefits necessary to basic sustenance have often been viewed as being of greater constitutional significance than less essential forms of governmental entitlements. See, e. g., Shapiro, supra; Goldberg v. Kelly, 397 U. S. 254, 264 (1970); Sniadach v. Family Finance Corp., 395 U. S. 337, 340-342 (1969). It would be odd, indeed, to find that the State of Arizona was required to afford Evaro welfare assistance to keep him from the discomfort of inadequate housing or the pangs of hunger but could deny him the medical care necessary to relieve him from the wheezing and gasping for breath that attend his illness.
  Nor does the fact that the durational residence requirement is inapplicable to the provision of emergency medical care save the challenged provision from constitutional doubt. As the Arizona Supreme Court observed, appellant “Evaro was an indigent person who required continued medical care for the preservation of his health and well being . . . ,” even if he did not require immediate emergency care. The State could not deny Evaro care just because, although gasping for breath, he was not in immediate danger of stopping breathing altogether. To allow a serious illness to go untreated until it requires emergency hospitalization is to subject the sufferer to the danger of a substantial and irrevocable deterioriation in his health. Cancer, heart disease, or respiratory illness, if untreated for a year, may become all but irreversible paths to pain, disability, and even loss of life. The denial of medical care is all the more cruel in this context, falling as it does on indigents who are often without the means to obtain alternative treatment.
  Finally, appellees seek to distinguish Shapiro as involving a partially federally funded program. Maricopa County has received federal funding for its public hospital but, more importantly, this Court has held that whether or not a welfare program is federally funded is irrelevant to the applicability of the Shapiro analysis. Pease v. Hansen, 404 U. S. 70 (1971); Graham v. Richardson, 403 U. S. 365 (1971).
  Not unlike the admonition of the Bible that, “Ye shall have one manner of law, as well for the stranger, as for one of your own country,” Leviticus 24:22 (King James Version), the right of interstate travel must be seen as insuring new residents the same right to vital government benefits and privileges in the States to which they migrate as are enjoyed by other residents. The State of Arizona's durational residence requirement for free medical care penalizes indigents for exercising their right to migrate to and settle in that State. Accordingly, the classification created by the residence requirement, “unless shown to be necessary to promote a compelling governmental interest, is unconstitutional.” Shapiro, 394 U. S., at 634. (Emphasis in original.)
  VI
  We turn now to the question of whether the State has shown that its durational residence requirement is “legitimately defensible,” in that it furthers a compelling state interest. A number of purposes are asserted to be served by the requirement and we must determine whether these satisfy the appellees’ heavy burden of justification, and insure that the State, in pursuing its asserted objectives, has chosen means that do not unnecessarily burden constitutionally protected interests. NAACP v. Button, 371 U. S. 415, 438 (1963).
  A
  The Arizona Supreme Court observed:
  “Absent a residence requirement, any indigent sick person . . . could seek admission to [Maricopa County’s] hospital, the facilities being the newest and most modern in the state, and the resultant volume would cause long waiting periods or severe hardship on [the] county if it tried to tax its property owners to support [these] indigent sick . . . .” 108 Ariz. 373, 376, 498 P. 2d 461, 464.
  The County thus attempts to sustain the requirement as a necessary means to insure the fiscal integrity of its free medical care program by discouraging an influx of indigents, particularly those entering the County for the sole purpose of obtaining the benefits of its hospital facilities.
  First, a State may not protect the public fisc by drawing an invidious distinction between classes of its citizens, Shapiro, supra, at 633, so appellees must do more than show that denying free medical care to new residents saves money. The conservation of the taxpayers’ purse is simply not a sufficient state interest to sustain a durational residence requirement which, in effect, severely penalizes exercise of the right to freely migrate and settle in another State. See Rivera v. Dunn, 329 F. Supp. 554 (Conn. 1971), aff’d, 404 U. S. 1054 (1972).
  Second, to the extent the purpose of the requirement is to inhibit the immigration of indigents generally, that goal is constitutionally impermissible. And, to the extent the purpose is to deter only those indigents who take up residence in the County solely to utilize its new and modern public medical facilities, the requirement at issue is clearly overinclusive. The challenged durational residence requirement treats every indigent, in his first year of residence, as if he came to the jurisdiction solely to obtain free medical care. Such a classification is no more defensible than the waiting period in Shapiro, supra, of which the Court said:
  “[T]he class of barred newcomers is all-inclusive, lumping the great majority who come to the State for other purposes with those who come for the sole purpose of collecting higher benefits.” 394 U. S., at 631.
  Moreover, “a State may no more try to fence out those indigents who seek [better public medical facilities] than it may try to fence out indigents generally.” Ibid. An indigent who considers the quality of public hospital facilities in entering the State is no less deserving than one who moves into the State in order to take advantage of its better educational facilities. Id., at 631-632.
  It is also useful to look at the other side of the coin — at who will bear the cost of indigents’ illnesses if the County does not provide needed treatment. For those newly arrived residents who do receive at least hospital care, the cost is often borne by private nonprofit hospitals, like appellant Memorial — many of which are already in precarious financial straits. When absorbed by private hospitals, the costs of caring for indigents must be passed on to paying patients and “at a rather inconvenient time” — adding to the already astronomical costs of hospitalization which bear so heavily on the resources of most Americans. The financial pressures under which private nonprofit hospitals operate have already led many of them to turn away patients who cannot pay or to severely limit the number of indigents they will admit. And, for those indigents who receive no care, the cost is, of course, measured by their own suffering.
  In addition, the County’s claimed fiscal savings may well be illusory. The lack of timely medical care could cause a patient’s condition to deteriorate to a point where more expensive emergency hospitalization (for which no durational residence requirement applies) is needed. And, the disability that may result from letting an untreated condition deteriorate may well result in the patient and his family becoming a burden on the State’s welfare rolls for the duration of his emergency care, or permanently, if his capacity to work is impaired.
  The appellees also argue that eliminating the dura-tional residence requirement would dilute the quality of services provided to longtime residents by fostering an influx of newcomers and thus requiring the County’s limited public health resources to serve an expanded pool of recipients. Appellees assert that the County should be able to protect its longtime residents because of their contributions to the community, particularly through the past payment of taxes. We rejected this “contributory” rationale both in Shapiro and in Vlandis v. Kline, 412 U. S. 441, 450 n. 6 (1973), by observing:
  “[Such] reasoning would logically permit the State to bar new residents from schools, parks, and libraries or deprive them of police and fire protection. Indeed it would permit the State to apportion all benefits and services according to the past tax contributions of its citizens. The Equal Protection Clause prohibits such an apportionment of state services.” Shapiro, 394 U. S., at 632-633 (footnote omitted).
  Appellees express a concern that the threat of an influx of indigents would discourage “the development of modern and effective [public medical] facilities.” It is suggested that whether or not the durational residence requirement actually deters migration, the voters think that it protects them from low income families’ being attracted by the county hospital; hence, the requirement is necessary for public support of that medical facility. A State may not employ an invidious discrimination to sustain the political viability of its programs. As we observed in Shapiro, supra, at 641, “[p]erhaps Congress could induce wider state participation in school construction if it authorized the use of joint funds for the building of segregated schools,” but that purpose would not sustain such a scheme. See also Cole v. Housing Authority of the City of Newport, 435 F. 2d 807, 812-813 (CA1 1970).
  B
  The appellees also argue that the challenged statute serves some administrative objectives. They claim that the one-year waiting period is a convenient rule of thumb to determine bona fide residence. Besides not being factually defensible, this test is certainly overbroad to accomplish its avowed purpose. A mere residence requirement would accomplish the objective of limiting the use of public medical facilities to bona fide residents of the County without sweeping within its prohibitions those bona fide residents who had moved into the State within the qualifying period. Less drastic means, which do not impinge on the right of interstate travel, are available and employed to ascertain an individual’s true intentions, without exacting a protracted waiting period which may have dire economic and health consequences for certain citizens. See Shelton v. Tucker, 364 U. S. 479, 488 (1960). The Arizona State welfare agency applies criteria other than the duration of residency to determine whether an applicant is a bona fide resident. The Arizona Medical Assistance to the Aged law provides public medical care for certain senior citizens, conditioned only on residence. Pinal County, Arizona, has operated its public hospital without benefit of the durational residence requirement since the application of the challenged statute in that County was enjoined by a federal court in Valenciano v. Bateman, 323 F. Supp. 600 (Ariz. 1971).
  The appellees allege that the waiting period is a useful tool for preventing fraud. Certainly, a State has a valid interest in preventing fraud by any applicant for medical care, whether a newcomer or oldtime resident, Shapiro, 394 U. S., at 637, but the challenged provision is ill-suited to that purpose. An indigent applicant, intent on committing fraud, could as easily swear to having been a resident of the county for the preceding year as to being one currently. And, there is no need for the State to rely on the durational requirement as a safeguard against fraud when other mechanisms to serve that purpose are available which would have a less drastic impact on constitutionally protected interests. NAACP v. Button, 371 U. S., at 438. For example, state law makes it a crime to file an “untrue statement . . . for the purpose of obtaining hospitalization, medical care or outpatient relief” at county expense. Ariz. Rev. Stat. Ann. § 11-297C (Supp. 1973-1974). See Dunn, 405 U. S., at 353-354; U. S. Dept. of Agriculture v. Moreno, 413 U. S. 528, 534 (1973).
  Finally, appellees assert that the waiting period is necessary for budget predictability, but what was said in Shapiro is equally applicable to the case before us:
  “The records . . . are utterly devoid of evidence that [the County] uses the one-year requirement as a means to predict the number of people who will require assistance in the budget year. [The appellees do not take] a census of new residents .... Nor are new residents required to give advance notice of their need for . . . assistance. Thus, the . . . authorities cannot know how many new residents come into the jurisdiction in any year, much less how many of them will require public assistance.” 394 U. S., at 634-635 (footnote omitted).
  Whatever the difficulties in projecting how many newcomers to a jurisdiction will require welfare assistance, it could only be an even more difficult and speculative task to estimate how many of those indigent newcomers will require medical care during their first year in the jurisdiction. The irrelevance of the one-year residence requirement to budgetary planning is further underscored by the fact that emergency medical care for all newcomers and more complete medical care for the aged are currently being provided at public expense regardless of whether the patient has been a resident of the County for the preceding year. See Shapiro, supra, at 635.
  VII
  The Arizona durational residence requirement for eligibility for nonemergency free medical care creates an “invidious classification” that impinges on the right of interstate travel by denying newcomers “basic necessities of life.” Such a classification can only be sustained on a showing of a compelling state interest. Appellees have not met their heavy burden of justification, or demonstrated that the State, in pursuing legitimate objectives, has chosen means which do not unnecessarily impinge on constitutionally protected interests. Accordingly, the judgment of the Supreme Court of Arizona is reversed and the case remanded for further action not inconsistent with this opinion.
  So ordered.
  The Chief Justice and Mr. Justice Blackmun concur in the result.
  Mr. Justice Douglas.
  The legal and economic aspects of medical care are enormous; and I doubt if decisions under the Equal Protection Clause of the Fourteenth Amendment are equal to the task of dealing with these matters. So far as interstate travel per se is considered, I share the doubts of my Brother Rehnquist. The present case, however, turns for me on a different axis. The problem has many aspects. The therapy of Arizona’s atmosphere brings many there who suffer from asthma, bronchitis, arthritis, and tuberculosis. Many coming are indigent or become indigent after arrival. Arizona does not deny medical help to “emergency” cases “when immediate hospitalization or medical care is necessary for the preservation of life or limb,” Ariz. Rev. Stat. Ann. § 11-297A (Supp. 1973-1974). For others, it requires a 12-month durational residence.
  The Act is not aimed at interstate travelers; it applies even to a long-term resident who moves from one county to another. As stated by the Supreme Court of Arizona in the present case: “The requirement applies to all citizens within the state including long term residents of one county who move to another county. Thus, the classification does not single out non-residents nor attempt to penalize interstate travel. The requirement is uniformly applied.” 108 Ariz. 373, 375, 498 P. 2d 461, 463.
  What Arizona has done, therefore, is to fence the poor out of the metropolitan counties, such as Maricopa County (Phoenix) and Pima County (Tucson) by use of a durational residence requirement. We are told that eight Arizona counties have no county hospitals and that most indigent care in those areas exists only on a contract basis. In San Antonio Independent School Dist. v. Rodriguez, 411 U. S. 1, we had a case where Texas created a scheme by which school districts with a low property tax base, from which they could raise only meager funds, offered a lower quality of education to their students than the wealthier districts. That system was upheld against the charge that the state system violated the Equal Protection Clause. It was a closely divided Court and I was in dissent. I suppose that if a State can fence in the poor in educational programs, it can do so in medical programs. But to allow Arizona freedom to carry forward its medical program we must go one step beyond the San Antonio case. In the latter there was no legal barrier to movement into a better district. Here a one-year barrier to medical care, save for “emergency” care, is erected around the areas that have medical facilities for the poor.
  Congress has struggled with the problem. In the Kerr-Mills Act of 1960, 74 Stat. 987, 42 U. S. C. § 302 (b)(2), it added provisions to the Social Security Act requiring the Secretary'of Health, Education, and Welfare to disapprove any state plan for medical assistance to the aged (Medicaid) that excludes “any individual who resides in the state,” thus eliminating durational residence requirements.
  Maricopa County has received over $2 million in federal funds for hospital construction under the Hill-Burton Act, 42 U. S. C. § 291 et seq. Section 291c (e) authorizes the issuance of regulations governing the operation of Hill-Burton facilities. The regulations contain conditions that the facility to be constructed or modernized with the funds “will be made available to all persons residing in the territorial area of the applicant” and-that the applicant will render “a reasonable volume of services to persons unable to pay therefor.” The conditions of free services for indigents, however, may be waived if “not feasible from a financial viewpoint.”
  Prior to the application the state agency must obtain from the applicant an assurance “that there will be made available in the facility or portion thereof to be constructed or modernized a reasonable volume of services to persons unable to pay therefor. The requirement of an assurance from an applicant shall be waived if the applicant demonstrates to the satisfaction of the State agency, subject to subsequent approval by the Secretary, that such a requirement is not feasible from a financial viewpoint.” 42 CFR § 53.111 (c)(1).
  So far as I can ascertain, the durational residence requirement imposed by Maricopa County has not been federally approved as a condition to the receipt of Hill-Burton funds.
  Maricopa County does argue that it is not financially feasible to provide free nonemergency medical care to new residents. Even so, the federal regulatory framework does not leave the County uncontrolled in determining which indigents will receive the benefit of the resources which are available. It is clear, for example, that the County could hot limit such service to whites out of a professed inability to service indigents of all races because 42 CFR § 53.112 (c) prohibits such discrimination in the operation of Hill-Burton facilities. It does not allow racial discrimination even against transients.
  Moreover, Hill-Burton Act donees are guided by 42 CFR § 53.111 (g), which sets out m some detail the criteria which must be used in identifying persons unable to pay for such services. The criteria include the patient’s health and medical insurance coverage, personal and family income, financial obligations and resources, and “similar factors.” Maricopa County, pursuant to the state law here challenged, employs length of county residence as an additional criterion in identifying indigent recipients of uncompensated nonemergency medical care. The federal regulations, however, do not seem to recognize that as an acceptable criterion.
  And, as we held in Thorpe v. Housing Authority, 393 U. S. 268; Mourning v. Family Publications Service, 411 U. S. 356, these federal conditions attached to federal grants are valid when “reasonably related to the purposes of the enabling legislation.” 393 U. S., at 280-281.
  It is difficult to impute to Congress approval of the durational residence requirement, for the implications of such a decision would involve weighty equal protection considerations by which the Federal Government, Bolling v. Sharpe, 347 U. S. 497, as well as the States, are bound.
  The political processes rather than equal protection litigation are the ultimate solution of the present problem. But in the setting of this case the invidious discrimination against the poor, Harper v. Virginia Board of Elections, 383 U. S. 663, not the right to travel interstate, is in my view the critical issue.
  APPENDIX TO OPINION OF DOUGLAS, J.
  Gourmand and Food — A Fable
  The people of Gourmand loved good food. They ate in good restaurants, donated money for cooking research, and instructed their government to safeguard all matters having to do with- food. Long ago, the food industry had been in total chaos. There were many restaurants, some very small. Anyone could call himself a chef or open a restaurant. In choosing a restaurant, one could never be sure that the meal would be good. A commission of distinguished chefs studied the situation and recommended that no one be allowed to touch food except for qualified chefs. “Food is too important to be left to amateurs,” they said. Qualified chefs were licensed by the state with severe penalties for anyone else who engaged in cooking. Certain exceptions were made for food preparation in the home, but a person could serve only his own family. Furthermore, to become a qualified chef, a man had to complete at least twenty-one years of training (including four years of college, four years of cooking school, and one year of apprenticeship). All cooking schools had to be first class.
  These reforms did succeed in raising the quality of cooking. But a restaurant meal became substantially more expensive. A second commission observed that not everyone could afford to eat out. “No one,” they said, “should be denied a good meal because of his income.” Furthermore, th&y argued that chefs should work toward the goal of giving everyone “complete physical and psychological satisfaction.” For those people who could not afford to eat out, the government declared that they should be allowed to do so as often as they liked and the government would pay. For others, it was recommended that they organize themselves in groups and pay part of their income into a pool that would undertake to pay the costs incurred by members in dining out. To insure the greatest satisfaction, the groups were set up so that a member could eat out anywhere and as often as he liked, could have as elaborate a meal as he desired, and would have to pay nothing or only a small percentage of the cost. The cost of joining such prepaid dining clubs rose sharply.
  Long ago, most restaurants would have one chef to prepare the food. A few restaurants were more elaborate, with chefs specializing in roasting, fish, salads, sauces, and many other things. People rarely went to these elaborate restaurants since they were so expensive. With the establishment of prepaid dining clubs, everyone wanted to eat at these fancy restaurants. At the same time, young chefs in school disdained going to cook in a small restaurant where they would have to cook everything. The pay was higher and it was much more prestigious to specialize and cook at a really fancy restaurant. Soon there were not enough chefs to keep the small restaurants open.
  With prepaid clubs and free meals for the poor, many people started eating their three-course meals at the elaborate restaurants. Then they began to increase the number of courses, directing the chef to “serve the best with no thought for the bill.” (Recently a 817-course meal was served.)
  The costs of eating out rose faster and faster. A new government commission reported as follows: (1) Noting that licensed chefs were being used to peel potatoes and wash lettuce, the commission recommended that these tasks be handed over to licensed dishwashers (whose three years of dishwashing training included cooking courses) or to some new category of personnel. (8) Concluding that many licensed chefs were overworked, the commission recommended that cooking schools be expanded, that the length of training be shortened, and that applicants with lesser qualifications be admitted. (3) The commission also observed that chefs were unhappy because people seemed to be more concerned about the decor and service than about the food. (In a recent taste test, not only could one patron not tell the difference between a 1930 and a 1970 vintage but he also could not distinguish between white and red wines. He explained that he always ordered the 1980 vintage because he knew that only a really good restaurant would stock such an expensive wine.)
  The commission agreed that weighty problems faced the nation. They recommended that a national prepayment group be established which everyone must join. They recommended that chefs continue to be paid on the basis of the number of dishes they prepared. They recommended that every Gourmandese be given the right to eat anywhere he chose and as elaborately as he chose and pay nothing.
  These recommendations were adopted. Large numbers of people spent all of their time ordering incredibly elaborate meals. Kitchens became marvels of new, expensive equipment. All those who were not consuming restaurant food were in the kitchen preparing it. Since no one in Gourmand did anything except prepare or eat meals, the country collapsed.
  Ariz. Rev. Stat. Ann. §11-291 (Supp. 1973-1974).
  Section 11-297A (Supp. 1973-1974) provides in relevant part that:
  “Except in emergency cases when immediate hospitalization or medical care is necessary for the preservation of life or limb no person shall be provided hospitalization, medical care or outpatient relief under the provisions of this article without first filing with a member of the board of supervisors of the county in which he resides a statement in writing, subscribed and sworn to under oath, that he is an indigent as shall be defined by rules and regulations of the state department of economic security, an unemployable totally dependent upon the state or county 'government for financial support, or an employable of sworn low income without sufficient funds to provide himself necessary hospitalization and medical care, and that he has been a resident of the county for the preceding twelve months.” (Emphasis added.)
  Thus, the question of the rights oí transients to medical care is not presented by this case.
  Arizona’s intermediate appellate court had also declared the durational residence requirement unconstitutional in Board of Supervisors, Pima County v. Robinson, 10 Ariz. App. 238, 457 P. 2d 951 (1969), but its decision was vacated as moot by the Arizona Supreme Court. 105 Ariz. 280, 463 P. 2d 536 (1970).
  An Arizona one-year durational residence requirement for care at state mental health facilities was declared unconstitutional in Vaughan v. Bower, 313 F. Supp. 37 (Ariz.), aff’d, 400 U. S. 884 (1970). See n. 11, infra.
  A Florida one-year durational residence requirement for medical care at public expense was found unconstitutional in Arnold v. Halifax Hospital Dist., 314 F. Supp. 277 (MD Fla. 1970), and Crapps v. Duval County Hospital Auth., 314 F. Supp. 181 (MD Fla. 1970).

  Appellees argue that the County should be able to apply a durational residence requirement to preserve the quality of services provided its longtime residents because of their ties to the community and the previous contributions they have made, particularly through past payment of taxes. It would seem inconsistent to argue that the residence requirement should be construed to bar longtime Arizona residents, even if unconstitutional as applied to persons migrating into Maricopa County from outside the State. Surely, longtime residents of neighboring counties have more ties with Maricopa County and equity in its public programs, as through past payment of state taxes, than do migrants from distant States. This “contributory” rationale is discussed, infra, at 266.
  Por a discussion of the problems posed by this ambiguity, see Judge Coffin’s perceptive opinion in Cole v. Housing Authority of the City of Newport, 435 F. 2d 807 (CA1 1970).
  In Vaughan v. Bower, 313 F. Supp. 37 (Ariz.), aff’d, 400 U. S. 884 (1970), a federal court struck down an Arizona law permitting the director of a state mental hospital to return to the State of his prior residence, any indigent patient who had not been a resident of Arizona for the year preceding his civil commitment. It is doubtful that the challenged law could have had any deterrent effect on migration, since few people consider being committed to a mental hospital when they decide to take up residence in a new State. See also Affeldt v. Whitcomb, 319 F. Supp. 69 (ND Ind. 1970), aff’d, 405 U. S. 1034 (1972).
  See Vlandis v. Kline, 412 U. S. 441, 452-453, n. 9 (1973).
  For example, the Shapiro Court cautioned that it meant to “imply no view of the validity of waiting-period or residence requirements determining eligibility [inter dial to obtain a license to practice a profession, to hunt or fish, and so forth.” 394 U. S., at 638 n. 21.

  Reference to the tuition cases is instructive. The lower courts have .contrasted in-state tuition with “necessities of life” in a way that would clearly include medical care in the latter category. The District Court in Starns v. Malkerson, 326 F. Supp. 234, 238 (Minn. 1970), aff’d, 401 U. S. 985 (1971), quoted with approval from Kirk v. Board of Regents, 273 Cal. App. 2d 430, 440, 78 Cal. Rptr. 260, 266-267 (1969), appeal dismissed, 396 U. S. 554 (1970) (emphasis added):
  “ ‘While we fully recognize the value of higher education, we cannot equate its attainment with food, clothing and shelter. Shapiro involved the immediate and pressing need for preservation of life and health of persons unable to live without public assistance, and their dependent children. Thus, the residence requirement in Shapiro could cause great suffering and even loss of life. The durational residence requirement for attendance at publicly financed institutions of higher learning [does] not involve similar risks. Nor was petitioner... precluded from the benefit of obtaining higher education. Charging higher tuition fees to non-resident students cannot be equated with granting of basic subsistence to one class of needy residents while denying it to an equally needy class of residents.' ”
  See also Note, The Constitutionality of Nonresident Tuition, 55 Minn. L. Rev. 1139, 1149-1158 (1971). Moreover, in Vlandis, supra, the Court observed that “special problems [are] involved in determining the bona fide residence of college students who come from out of State to attend [a] public university . .. ,” since those students are characteristically transient, 412 U. S., at 452. There is no such ambiguity about whether appellant Evaro is a bona fide resident of Maricopa County.

  Medicaid, the primary federal program for providing medical care to indigents at public expense, does not permit participating States to apply a durational residence requirement as a condition to eligibility, 42 U. S. C. § 1396a (b)(3), and “this conclusion of a coequal branch of Government is not without significance.” Frontiero v. Richardson, 411 U. S. 677, 687-688 (1973). The State of Arizona does not participate in the Medicaid program.

  The Arizona Supreme Court observed that because this case involves a governmental benefit akin to welfare, the “reasonable basis” test of Dandridge v. Williams, 397 U. S. 471 (1970), should apply. In upholding a state regulation placing an absolute limit on the amount of welfare assistance to be paid a dependent family regardless of size or actual need, the Court in Dandridge found it “enough that the State’s action be rationally based and free from invidious discrimination.” Id., at 487. The Court later distinguished Dandridge in Graham v. Richardson, 403 U. S. 365, 376 (1971), where Mr. Justice Blacicmun, writing for the Court, observed that “[appellants’ attempted rebanee on Dandridge ... is also misplaced, since the classification involved in that case [did not impinge] upon a fundamental constitutional right . . . .” Strict scrutiny is required here because the challenged classification impinges on the right of interstate travel.
