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, San Francisco, and California. Data for the United States are from the Pew Research Center report by Fry & Passel (July 2014) for 2007-2012, the Pew Research Center report by Cohn & Passel (August 2016) for 2014, and unpublished estimates from the Pew Research Center for 2013 and 2015. Silicon Valley data include 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.
