Also, does anyone have data on the geographical distribution of rookies in the 2009, 2010, and 2011 seasons, as compared to 2007 and 2008?

I would hazard a guess that the district model in MI has spawned a disproportionately large number of teams there, because of the reduced cost. I know MI already has a disproportionately high density of FRC teams, what with the US Automakers all being based there.

EDIT: I also worry about the caliber of teams we're creating. FIRST has seen huge growth in the last 4 years. I've only noticed a handful of teams with numbers over 2500 (roughly 2009-era rookies) that have been notably strong on the field. This is that quantity over quality argument everyone keeps making.
