Passage: Abortion rates also vary depending on the stage of pregnancy and the method practiced. In 2003, the Centers for Disease Control and Prevention (CDC) reported that 26% of reported legal induced abortions in the United States were known to have been obtained at less than 6 weeks gestation, 18% at 7 weeks, 15% at 8 weeks, 18% at 9 through 10 weeks, 9.7% at 11 through 12 weeks, 6.2% at 13 through 15 weeks, 4.1% at 16 through 20 weeks and 1.4% at more than 21 weeks. 90.9% of these were classified as having been done by "curettage" (Suction-aspiration abortion, dilation and curettage, dilation and evacuation), 7.7% by "medical abortion" means (mifepristone), 0.4% by "instillation abortion" (saline or prostaglandin), and 1.0% by "other" (including hysterotomy abortion and hysterectomy). According to the CDC, due to data collection difficulties the data must be viewed as tentative and some fetal deaths reported beyond 20 weeks may be natural deaths erroneously classified as abortions if the removal of the dead fetus is accomplished by the same procedure as an induced abortion.
At what ages were the least amount of abortions obtained? Between which two age groups is the largest variance in abortions? By how many percent does the prevalence of abortions at 10 and 11 weeks differ? How many abortions, by percent, occurred after 6 weeks gestation as reported by the CDC in 2003? How many fewer abortions, by percent, are performed during week 7 than in week 6? How many more abortions were done by medical abortion compared to those classified by instillation abortion? How many more abortions were performed, by percent, in 2003 at 9 through 10 weeks compared to those at 11 through 12 weeks? How many more reported legal inducted abortions were there in the United States in 2003 at 9 through 10 weeks gestation compared to 11 through 12 weeks? How many percent of abortions are performed by hysterectomy? Were more abortions done by curettage or by medical abortion? What are the four different classifications of abortion? What is used for an instillation abortion? What procedure represents the most legal induced abortions? What weeks have the highest percentage of abortions? What weeks have the lowest percentage of abortions? Which ages saw less than 5% of the total abortions? Which gestation week were there more reported legal induced abortions in the United States, 7 weeks or 8 weeks? Which method of abortion was the least commonly used? Which method was most commonly used for abortions? Which weeks have between 5% and 10% of abortions? Which were there more abortions reported by the CDC in 2003, those at 7 weeks gestation or those at 8 weeks gestation?
