Editing Minor civil division

{{short description|Governmental divisions of U.S. counties, such as civil townships}}
A '''minor civil division''' (MCD) is a term used by the [[United States Census Bureau]] for primary [[government]]al and/or [[administrative division]]s of a [[county (United States)|county or county-equivalent]], typically a municipal government such as a city, town, or [[civil township]]. MCDs are used for statistical purposes by the Census Bureau, and do not necessarily represent the primary form of local government. They range from non-governing geographical survey areas to municipalities with weak or strong powers of self-government. Some states with large unincorporated areas give substantial powers to counties; others have smaller or larger incorporated entities with governmental powers that are smaller than the MCD level chosen by the Census.

As of 2010, MCDs exist in 29 states, the [[District of Columbia]], and Puerto Rico. In all other states where state-defined entities are not used for census purposes (mostly in the South and the West), the Census Bureau designates [[Census County Division]]s (CCDs). For several decennial censuses prior to the [[2010 United States census|2010 census]], 28 states used MCDs, but in 2008, Tennessee changed from CCDs to MCDs, bringing the total number of MCD states to 29.<ref name=Census2011definition>{{cite web |url=https://www.census.gov/geo/reference/gtc/gtc_cousub.html |title=Geographic Terms and Concepts – County Subdivision |author=U.S. Census Bureau, Geography Division |date=February 2011 |access-date=July 10, 2012 |publisher=United States Census Bureau |archive-date=December 10, 2016 |archive-url=https://web.archive.org/web/20161210164725/http://www.census.gov/geo/reference/gtc/gtc_cousub.html |url-status=live }}</ref>

In states that use MCDs, when any land or water is not covered by a state-defined MCD, the Census Bureau creates additional entities as [[unincorporated area#U.S. Census Bureau|unorganized territories]], that it treats as equivalent to MCDs for statistical purposes.  Because MCDs are used to divide up counties, when a MCD-level municipality or unallocated territory or water spans county boundaries, that entity's boundaries are used to create multiple MCDs, one for each county. For water areas unallocated to any MCD, the Census Bureau assigns a default [[Federal Information Processing Standard|FIPS]] county subdivision code of 00000 and an [[ANSI]] code of eight zeroes.<ref name=Census2011definition/> This typically happens when state and county boundaries extend into the ocean or [[Great Lakes]], but MCDs are not defined by the state for the unoccupied water. (For the ocean boundary of state vs. federal responsibility, see [[Tidelands]].)

The U.S. Census considers all of Palau a county equivalent, and uses its [[States of Palau|states]] (formerly known as municipalities) as MCDs.<ref>{{cite web |author=U.S. Census Bureau |title=Guide to State and Local Census Geography |url=http://www2.census.gov/geo/pdfs/reference/guidestloc/All_GSLCG.pdf |archive-url=https://web.archive.org/web/20161210054254/http://www2.census.gov/geo/pdfs/reference/guidestloc/All_GSLCG.pdf |archive-date=10 Dec 2016}} (updated for 2010 Census)</ref>{{Failed verification|date=August 2024}}
