Maybe because PP does more than just abortion?

Abortions make up 3.4 percent of the services Planned Parenthood performs, an increase from 3 percent the previous year. Testing for sexually transmitted diseases comprises the largest share of Planned Parenthood services, at 48.7 percent, and next is contraception at 27.1 percent. An additional 6.3 percent of medical services performed are cancer screenings and prevention, a drop from 7 percent during the previous fiscal year. In all, Planned Parenthood saw 2.4 million patients across the U.S.
