the U.S. Virgin Islands. (See Majority minority). In 2017, demographer Dudley L. Poston Jr. argued that "Whites are now the numerical minority in a half dozen states, and they will be the nation's numerical minority in a little more than 25 years (referring to non-Hispanic Whites only). And now, for the first time ever, there are fewer White than non-White children under 10 years of age." The non-Hispanic White percentage of the 50 states and District of Columbia (60.1% in 2019) has been decreasing since the mid-20th century as a result of changes made in immigration policy, most notably the Hart–Celler Act of 1965. If current trends continue, non-Hispanic Whites will drop below 50% of the overall U.S. population by 2043. White Americans overall (non-Hispanic Whites together with White Hispanics) are projected to continue as the majority, at 73% (or 303 million out of 420 million) in 2005, from currently 77%. Although a high proportion of the population is known to have multiple ancestries, in the 2000 U.S. census, the first with the option to choose more than one, most people still identified with one racial category. In the 2000 census, self-identified German Americans made up 17% of the U.S. population, followed by Irish Americans at 12%, as reported in the 2000 census. This makes German and Irish the largest and second-largest self-reported ancestry groups in the United States. Both groups had high rates of immigration to the U.S. beginning in the mid-19th century, triggered by the Great Famine in Ireland and the failed 1848 Revolution in Germany. However, English Americans and British Americans are still considered the largest ethnic group due to a serious undercount following the 2000 census whereby many English and British Americans self-identified under the new category entry 'American' considering themselves 'indigenous' because their families had resided in the US for so long or, if of mixed European ancestry, identified with a more recent and differentiated ethnic group. 7.2% of the population listed their ancestry as American on the 2000 census (see American ancestry). According to the United States Census Bureau, the number of people in the U.S. who reported American and no other ancestry increased from 12.4 million in 1990 to 20.2 million in 2000. This change in reporting represented the largest "growth" of any ethnic group in the United States during the 1990s, but it represented how people reported themselves more than growth through
