California's Housing Boom Fails to Alleviate Affordability Crisis Amid Demographic Shifts
California has added 677,000 housing units over six years while its population grew by only 39,000, according to the Public Policy Institute of California (PPIC). Despite this increase in housing, the state's market remains tight, with owner vacancy rates falling from 1.2% to 0.8% and rental vacancy rates at 4.3%, below the national average of 5.9%. The demand for housing is driven by demographic changes, including an aging population and smaller household sizes. From 2019 to 2024, California lost 82,000 households with children but gained 722,000 households without them, leading to more housing needed per person. The state estimates it requires 2.5 million more homes over the next eight years, double the current plans.
