Bill Summary · AB 91

Legislative bill overview

AB 91 requires California state and local agencies to collect, maintain, and report demographic data on the populations they serve. The bill standardizes data collection practices across agencies and establishes requirements for disaggregating data by race, ethnicity, gender, age, disability status, and other demographic categories to better understand service disparities.

Why is this important

Demographic data collection enables policymakers and agencies to identify whether public services are reaching all communities equitably or if certain groups face barriers to access. This information is foundational for addressing systemic inequities in education, healthcare, criminal justice, social services, and other government programs. Without standardized data, agencies cannot effectively measure or address disparities.

Potential points of contention

  • Privacy concerns: Collecting and storing detailed demographic information raises questions about data security, consent, and potential misuse of sensitive personal information by government agencies
  • Implementation costs and burden: Requiring agencies statewide to revise data systems and processes could impose significant financial and administrative costs, particularly for smaller local governments
  • Standardization challenges: Different agencies serve different populations with different data systems; creating uniform collection standards may be technically complex and require substantial coordination
