AB 1878: Data collection: race and ethnicity.

The bill aims to improve data collection on racial and ethnic diversity in California. It requires state agencies to collect and publish demographic data on detailed race and ethnicity categories. The bill must be implemented by January 1, 2029. Agencies must submit reports to the legislature on compliance with the new provisions every year. The data collected must be made available to the public, except for personal identifying information. Agencies must adhere to best practices in government data and apply data equity practices. The bill makes findings to justify limiting access to public meetings and writings.
