California Women's Health Survey

The California Women's Health Survey (CWHS) was established in March 1997 to provide information to policy-makers and health professionals about women's health and to serve as a catalyst for innovative solutions that impact the health of California's women and girls. The CWHS is an annual telephone survey that collects information from a sample of approximately 4,000 randomly selected women aged 18 years or older on a wide variety of health indicators and health-related knowledge, behaviors, and attitudes.

Participation in the CWHS is completely voluntary and anonymous. Interviews are conducted by trained interviewers following standardized procedures developed by SRG staff and the Centers for Disease Control and Prevention (CDC). The survey collects data monthly from a random sample of California adult women living in households with telephones. Quality control procedures are rigorous to ensure a high level of accuracy in the data collected.

  • Mode of Administration: Telephone interview conducted in English and Spanish.
