This visualization depicts the growth of special districts from 1952 to 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.
There were 89,527 governments in the U.S. in 2007, up from 87,576 in 2002.
