San Mateo County Families: Structure and Composition
In San Mateo County and throughout the country, families are a major focus of the American Community Survey (ACS), conducted each year by the U.S. Census Bureau. A family in San Mateo County, as defined by the Census, includes a householder and all the other people in the housing unit related to him or her, by birth, marriage, or adoption.
Not all households in San Mateo County are family households. Nonfamily households include those composed of unrelated roommates, or single-person households. In addition, family households may include non-family members who live in the same housing unit. Note that the data in this report presents estimated counts of households in San Mateo County, not of people.
Unlike the Census—which is an exact count of people and households every ten years—ACS statistics are estimated based on a representative survey sample. For locations with populations under 60,000, the ACS is only available in 5-year estimates, rather than single-year periods. The 5-year estimates provide greater geographical granularity but a less granular time period.
