  • Who else do you vote with?  Who are your elected representatives?  How did the lines change from the previous districts?  How do your city, county, school board, state, and congressional districts fit together?  Did your districts grow or shrink in area?  How would you describe your districts (competitive, gerrymandered, representative)?
  • Recall the information you identified while describing your community.  What else do you need to consider when drawing districts?  What watershed do you live in?  What school districts serve your area?  What issues are decided by state legislatures and local elected bodies that you care about?
  • County and municipal jurisdictions are also important to monitor.
