National Vital Statistics System—Linked Birth and Infant Death Data (NVSS-I)


U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS).

Mode of Administration

Linked Birth and Infant Death Data is part of the Nation's vital and health statistics. Vital statistics are provided through state-operated registration systems. See 'National Vital Statistics System-Mortality' for administrative records of death certificates and 'National Vital Statistics System-Natality' for administrative records of birth certificates.

Survey Sample Design

In the linked birth and infant death data set the information from the death certificate is linked to the information from the birth certificate for each infant under 1 year of age who dies in the United States, Puerto Rico, The Virgin Islands, and Guam.

Primary Survey Content

The linked files include information from the death and birth certificates. The mortality data is a fundamental source of geographic and cause-of-death information, and some demographic information. The natality data is a primary source of demographic information, and maternal and infant health information. See 'National Vital Statistics System-Mortality' and 'National Vital Statistics System-Natality' for detailed information.
