California Department of Aging Data & ReportsThe CDA annual California Aging Population Demographic Projections report provides older adult population data by County and Planning Service Area (PSA) level. The statistics include age, minority and non-English demographics, geographic isolation (rural), individuals living alone, and Medi-Cal and Supplemental Security Income (SSI)/State Supplementary Payment (SSP) participants. These factors are used to develop planning estimates for the local assistance allocation of federal and State funds to the Area Agencies on Aging (AAA) as part of the Intrastate Funding Formula (IFF).
