It was just the quickest thing I could easily find. I have no reason to doubt their stats on services provided, but if you or anyone else can demonstrate that they're not correct, I'm happy to see the numbers you find.
I also found it curious that they gave stats on so many other things, but not the number of abortions performed.
All of that said, I'm not trying to demonstrate that they're somehow perfect as an organization, or that they don't perform abortions; obviously they're not perfect and they do perform abortions. However, it's pretty clear that those who claim that abortions are all PP does (or even a large percentage of what it does) are either misinformed or being deliberately untruthful.
