Our Wisconsin mapmaking efforts for the 2021 redistricting cycle began Oct. 17, 2021. Since then our FastMap algorithm has generated numerous exceptional maps for Wisconsin's legislative and congressional districts. A sample of these maps is provided below.
(Feb. 24, 2024) Comparison of the seven map proposals submitted to the Wisconsin Supreme Court on January 12, 2024 with most metrics computed by DavesRedistricting.org. Our proposal (named "173#008") was the best according to 11 of 12 metrics of political neutrality. It also had significantly better district shapes and a significantly greater number of competitive districts than any other proposal. It also had the best performance for Native Americans and nearly the best performance for county splitting (narrowly coming in second).
