The MIHA project is an annual population-based survey ongoing since 1999 that collects data to monitor key maternal and infant health outcomes and access to services across California.
The MIHA survey is conducted by the UCSF Center for Health Equity in collaboration with the Maternal, Child, and Adolescent Health (MCAH) Division of the California Department of Public Health. MIHA survey data are used to inform efforts to support the well-being of California’s families.
Every year over 4,500 California residents with a recent live birth share their birth and postpartum experiences with MIHA via mail, telephone, and web surveys. MIHA data are used to identify maternal and infant health needs and priorities in California's diverse communities.
