What you see below is the first step toward a comprehensive interactive map of all American campus occupations during the 2011-12 academic year. It’s not close to done — I’ve got a lot more data to add, for starters — but it’s a beginning.

Fall 2011 occupations are marked in yellow. Spring 2012 (most of which aren’t on the map yet) are in blue. Occupations that saw arrests or other police violence are in red.

Each marker contains at least one link to the occupiers’ blog/Twitter/Facebook info and/or to media coverage of the action. Click here for the full map with a complete explanation and chronological list of occupations.

If you have info about occupations not listed here, or more data about occupations that ARE listed, please share. Include links if you can.
