* Unincorporated communities are not municipalities or self-governing jurisdictions. They fall fully under the jurisdiction of county government. All local public services are received from the county government. Communities listed above are all "Census Designated Places," according to the U.S. Census Bureau. These are not incorporated cities or towns, but are identified as significantly populated communities for the purposes of the census.
† Estimated numbers calculated each year between the decennial census counts. These numbers are calculated from surverys over the previous five-year period.
‡ The formerly unincorporated communities of Newhall and Valencia became part of the city of Santa Clarita, incorporated in 1987.
** The populations of the unincorporated communities of West Rancho Dominguez (formerly named West Compton) and Willowbrook dramatically shifted between 2010 and 2020, due to a major boundary change between the two adjacent communities. A geographic portion of Willowbrook was transferred over to West Rancho Dominguez prior to the 2020 Census, shifting a large portion of the population from Willowbrook to West Rancho Dominguez.
