I've certainly seen those stats too, although I'm having trouble finding them. I do know that the availability of abortion across the states drops dramatically the further south and the further into lower-income areas you go.

The following states have one clinic each:

Arkansas
Mississippi
North Dakota
South Dakota
Wyoming

And the requirements are so onerous!

I kept my own sanity a couple of years ago by sending encouraging postcards to one clinic in each state, thanking them for giving women a choice. It was heartbreaking to find so many states with only one - and I think that was only two states then. That it's five now makes my heart sink further.
