I’ve been asked by a number of people where a good map of Pima County’s justice precincts can be found. These are the political districts that elect justices of the peace and constables. The county’s web-based GIS map viewer, PimaMaps, has a layer for this. But the information in it is sparse, and casual users may find PimaMaps difficult to navigate. So I made a map I hope folks will find more instructive and easier to use.

This is a color-coded “choropleth” map that uses shades of red and blue to indicate voter registration advantage in each precinct.  It is similar to maps I have recently made of Arizona’s congressional and legislative districts. If you hover your mouse over a precinct, the map will display the current justice of the peace and constable serving there, plus detailed information about voter registration in that precinct.
