Abortion Rates in the United States, 1970-2005
The darker the shade of green, the higher the number of reported abortions per 1,000 live births.
New York has the highest rate with a whopping 507, which is a little over a third. That I'm not so sure about though. I'm thinking that there might be some high numbers in the '70s driving that rate up, but I'd have to look deeper into that. Wyoming, on the other hand, only had a reported 14 abortions between 1970 and 2005.
In retrospect, the choice of green probably wasn't the best color choice, but seeing as this is just practice, I don't think it's a big deal.
How I Made It
In case you're wondering, I made the basemap in R using the maps and maptools packages. It was actually only 5 or 6 lines of code after I got the data how I wanted it. Then as I always do, I brought the PDF into Adobe Illustrator for some touch-ups and annotation.

UPDATE: I revised the map using the Albers projection, so it doesn't look so funky. Of course, it was more difficult than originally thought. Tutorial to come.
