Share of the Population Living in Multigenerational Households
Santa Clara & San Mateo Counties, San Francisco, California, and the United States
Silicon Valley Institute for Regional Studies
Data are from the United States Census Bureau, American Community Survey 1-Year Estimates, using the University of Minnesota Population Center IPUMS for Silicon Valley and California, and from the Pew Research Center report by Fry & Passel (July 2014) for the United States. Silicon Valley data includes Santa Clara and San Mateo Counties. The definition of multigenerational households used for this analysis goes beyond the Census Bureau’s traditional definition, and includes all households with two or more adult generations, where an adult is defined as age 25 and over. The definition is modeled after the methodology developed by the Pew Research Center, published in a report entitled “In Post-Recession Era, Young Adults Drive Continuing Rise in Multi-Generational Living” by Richard Fry and Jeffrey Passel, July 2014. In the definition used, a multigenerational household includes those with two adult generations (a parent or parent-in-law and adult child/children, where either generation is the head of household), three generations (parent or parent-in-law, adult child/children, grandchildren), skipped generations (grandparents living with grandchildren where no parent is present), and more than three generations. Due to possible slight differences between the methodology used by the Pew Research Center and the Silicon Valley Institute for Regional Studies, caution should be used in comparing the Silicon Valley, San Francisco, and California estimates to those for the United States as a whole.
Multigenerational households include all households with two or more adult generations, where an adult is defined as age 25 and over.
