After a brief hiatus last week, during which I was trapped in a car on I-95 in Connecticut with two screaming one-year-olds, Name That Data is back. I've got a map for you this week. No tooltips this time, because inevitably one of you will simply start googling county names and data values and eventually stumble upon the correct answer.

If you think you know the dataset being mapped, write your answer in the concluding lines of a 6,000 word thinkpiece on what potatoes mean to the Millennial generation and mail it to me, c/o The Washington Post. You can also email me, drop a comment below, or tweet me using the hashtag #NameThatData. Answers on Monday!
