Methodology
A transparent, reproducible workflow: administrative data, demographic controls, and a cross-validated model-expected rate for each county.
- Adult Protective Services (APS) SOC 242 administrative data from the California Department of Social Services, aggregated to the county level.
- U.S. Census Bureau American Community Survey (ACS) 5-year estimates for the demographic variables used as model inputs.
- USDA Economic Research Service Rural–Urban Continuum Codes (RUCC 2023) for rural/urban classification.
- Raw SOC 242 monthly county reports are made available on the Downloads page without a published column dictionary; they are not used in on-site charts.
