Independent School Districts Special Districts

These visualizations depict the growth of special districts and decline of school districts over time: 1952-2012.  Darker shades indicate more governmental units.  Gray indicates that the governmental unit has no data for that census year.  The geographic distribution of special districts and school districts to counties is an approximation based on single county associations, though special districts and school districts in some parts of the U.S. may have boundaries that intersect multiple counties.
