The second installment of Name That Data is here! Since a whole bunch of you figured it out last time I'm going a little lighter on the hints this go-round. Again, I've mapped out a county-level dataset below. I don't mean to keep doing counties, but this one was too good to pass up, and let's face it -- everyone loves county maps!
Your job -- tell me the quantity mapped, either in the comments below, on Twitter by tweeting @_cingraham using the hashtag #NameThatData (the hashtag is important!! it helps me tally all the responses at the end), or simply by e-mailing me with "Name That Data" in the subject line. For hints, you get the following: A) it's a percentage of something and B) it has to do with money.
Do your worst and I'll see you Monday.
