If specific LACHS data tables you need are unavailable on our website, you may request data from us. We routinely fulfill customized data requests from community-based organizations, advocacy groups, researchers, and government agencies. Turn-around time may vary depending on the nature and complexity of the request. But we strive to provide the requested data within a couple of weeks.

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 (LAHealthData@ph.lacounty.gov).
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.
