Description: The Polk County Commissioner Districts layer was developed within the Polk County GIS based on the 2010 Census data and in conformity with the Environmental System Research Institute (ESRI) redistricting process. This layer has been approved and adopted by the Polk County Board of County Commissioners in 2011. Legal descriptions for each area extent for each district has been written by the Polk County Surveyer. The layer provides information such as the commissioner name and district represented, total population for each district, population of different races for each district, and number of occupied/unoccupied housing units for each district. This layer is updated whenever there is a changer in commissioner for a district and/or whenever the census deems a change due to population changes.
