"Population Bracketology" is being called an "addictive pastime for anyone who thinks they know the relative size of every major American city." So, I wasn't surprised at all when I asked my Geographic Information Systems (GIS) guy Kevin if he'd played it and he said yes, and he'd done pretty well.
Here's how it works: Start by choosing your geographic level: metro areas or states. Click on the name in each match-up that you think has the larger population. Green shows a correct answer, red indicates an incorrect answer. When you have opposing names picked for the next round, pick again. See how close you can come to a perfect score of 63. When you are finished, play again or mouse-over results to view the most current population estimates for each pair.
