And now for a Friday distraction with a side of edification: The Census Bureau has created a mobile quiz that tests your knowledge of D.C. and the 50 states.

Using information from the American Community Survey, the Census PoP Quiz features five questions about each state/should-be state’s population. For D.C., this includes questions about the percentage of commuters who use a vehicle and who live in a studio apartment. Our only complaint about the quiz: It needs more questions!
