We routinely fulfill customized data requests from community-based organizations, advocacy groups, researchers, and government agencies.

Please call (213) 288-7785, Monday through Friday, or email ( for further assistance. 

Open Data Sets

We are making available de-identified data collected in the 2015 and 2018 surveys to external researchers and data users. These raw data sets include all the variables we collected except for sub-county geographic information. Data can be analyzed and used for research, planning, and evaluation. To request the data sets, please submit the Data Access Form to us via email (

Data for Research Collaboration

If sub-county geographic data from the survey are needed for research purposes, researchers may request the data by entering into a formal research agreement with the Office of Health Assessment and Epidemiology (OHAE). The Los Angeles County Department of Public Health (LAC-DPH) is interested in making the best possible use of the data and furthering collaborations with academic centers and other institutions. Requests to use the LACHS data sets are considered on a case-by-case basis.
