The National Center for Health Statistics (NCHS) is the nation’s principal health statistics agency, providing data to identify and address health issues. NCHS compiles statistical information to help guide public health and health policy decisions.

Collaborating with other public and private health partners, NCHS employs a variety of data collection mechanisms, including the NationalVital Statistics System, 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.

The NationalVital Statistics System (NVSS) provides the nation’s officialVital statistics based on the collection and registration of birth and death events at the state and local level. This system contains information on all births and deaths in the United States and provides the most complete and continuous data available to public health officials at the national, state and local levels, and in the private sector.

Examples from the NVSS include teen births and birth rates; preterm birth and infant mortality rates; leading causes of death; and life expectancy.Vital statistics have diverse uses - they serve as a base for public health, social service, and economic planning and program development and are used to track progress toward health goals.

Each year, the NVSS collects information on 6.5 million birth, death and fetal death events occurring in the 57 U.S.Vital registration areas (50 states, New York City, District of Columbia, and five U.S. territories). NCHS also works with eachVital registration area and the National Association for Public Health Statistics and Information Systems (NAPHSIS) - representing stateVital statistics’ offices - to collectVital registration data and to improve timeliness and data quality.

Efforts to improveVital records are ongoing - they involve NCHS support of states in implementing electronic birth and death registration systems and completing the implementation of the 2003 revised standard certificates in all jurisdictions. Electronic birth and death records will improve timeliness of data, allow for transfer of data between states, and integrateVital statistics with public health surveillance systems. As of 2013, NCHS completed the funding of remaining states seeking assistance for development and/or implementation of a web-based electronic birth registration system (EBRS). Similar progress has not been made with electronic death registration systems (EDRS). As of 2013, 37 of the 57Vital registration areas have an operating EDRS, although most of these systems are not operating statewide and most data providers (physicians, funeral homes) are not using them to enter the death information.
