In 1960, the National Office of Vital Statistics and the National Health Survey merged to form the National Center for Health Statistics (NCHS). NCHS is one of 13 principal statistical agencies in the federal government. The Center has been located in a number of organizations within the Department of Health and Human Services (HHS), and since 1987 has been part of the Centers for Disease Control and Prevention (CDC).

Collaborating with other public and private health partners, NCHS employs a variety of data collection mechanisms to obtain accurate information from multiple sources. This process provides a broad perspective to help us understand the population’s health, influences on health, and health outcomes. We collect data from birth and death records, medical records, interview surveys, and through direct physical examinations and laboratory testing.
