The Los Angeles County Health Survey is a population
based telephone survey that provides information
concerning the health of Los Angeles County
residents. The data are used for assessing
health-related needs of the population, for program
planning and policy development, and for program
evaluation. The relatively large sample size allows
users to obtain health indicator data for large
demographic subgroups and across geographic regions of
the County, including Service Planning Areas and Health
Districts.
