That doesn't mean 27 to 30% of all abortions are white, it means that 27 to 30% of white babies are aborted. So while other races are more likely to get the procedure, the majority is still done on white women.

It looks like blacks get more because it is a per capita ratio. You could look at the raw numbers instead of being confused by percentages of pregnancies of demographic populations.

Statistics are usually meant to push a narrative rather than to convey information. We could do the work and take the raw data to show the actual percentage of each demographic, it would surely show that white babies are aborted more than nonwhite babies. But think about this: why is that data not conveyed and the per capita ratio conveyed instead?

I speculate it is because displaying the data this way supports the liberal narrative that abortion access is important to minorities. It also tricks conservatives and nationalists into considering the pro-infanticide position by highlighting how white women are less likely to get the procedure while omitting the ratio of each demographic to the total number of abortions.
