State & County QuickFacts

Need to know how many people live in your state or home town?  Need some basic facts about the businesses in your area?  The Census Bureau's State & County QuickFacts site may fulfill your needs:

After you select a geographic area, the site provides a quick statistical overview of the population, housing, and businesses in that area, along with the number of square miles occupied and the persons per square mile.  It also provides totals for the U.S. as a whole, and for the younger information seeker, there's a link to "Student State Facts." 

In case of zombie apocalypse, it might be very helpful to know that Georgia has 168.4 people per square mile, but Washington, DC has 9,856.5.  (Wyoming, with 5.8 people per square mile, is the place you'd want to be.)
