I'm trying to figure out how to find historical population and demographics data for San Francisco.
Dear Ms. McCarthy,
Thank you for posting your request on History Hub!
We suggest that you review the United States Census Bureau’s Explore Census Data site or About the Census Library to build information on the historical demographics and population patterns of San Francisco. We also suggest that you contact the San Francisco History Center for more information.
