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.
