Black Americans have more abortions per capita because they are more likely to be poor. Poverty is absolutely correlative with abortion rates. Wealthier people have abortions too, of course, including some who are supposedly "pro-life" (it's easier to surreptitiously have an abortion when you have the funds and the means) , but abortion is much more common among low-income women. Banning abortion doesn't prevent abortions from occurring. Following the overturning of Roe, demand for abortions soared in states where it's still legal due to people coming in from states where it is banned. What might prevent abortions, however, is more social welfare for the impoverished. So that those people do not feel like their lives will be over if they have another child. If you really want to stop abortion, then stop the motive for it, including supporting access to and encouraging the use of contraception. As long as the pro-life movement continues to think that women who get abortions are bloodthirsty baby-killing monsters, they will get nowhere in their cause.
