CIRCLE’s new interactive maps of states and congressional districts are getting a lot of attention. Our congressional district map lets you view any district by various measures of demographics, turnout, socioeconomic variables, the number of local colleges and universities, and two political factors (whether any state ballot measures might mobilize youth in 2014, and whether the district is competitive).

You can compare rates by district, look over time, and see all the districts ranked from highest to lowest. Using some of those tools, we have identified four districts–IA-3, AZ-1, AZ-9, and NY-23–as especially interesting to watch in 2014 if you care about the youth vote.

Previously, we had released a state map (pertinent to Senate races, among other purposes) that shows historical youth turnout rates and other data going back to the 1970s.
