How big is government? Well, this survey of local agencies in the US may clarify that for you. The US Census Bureau has just released the data and findings from the 2012 Census of US Governments. The Individual State Descriptions provide the foundation of how government entities are identified and classified for the U.S. Census Bureau statistics on governments. Conducted every five years, the census of governments provides the only uniform source of statistics for all of the nation’s state and local governments.
