Married couple families are no longer the majority of households in San Diego County. According to the recently released census data, the proportion of husband-wife families fell from 50.7 percent of households in 2000 to 48.9 percent in 2010. The decade saw a growth in the proportion of non-family householders and female family householders without husbands.
The decennial census is the most comprehensive count of population demography. There are a little over a million households in the San Diego region, with 72 percent of the households being family households.According to the Census Bureau, a family household contains at least two persons — the householder and at least one other person related to the householder by birth, marriage or adoption. Family households could be married couple or a male/female householder with no spouse present.
Family couples constituted a majority of all households until 2000. A nonfamily household may have one or more people who are not relatives of the householder. This includes room-mates, live-in nannies or caregivers. Not included in the household counts are group quarters such as college dorms, nursing facilities, military barracks, and prisons.
