The National Vital Statistics System (NVSS) is a program in the United States that collects and disseminates vital statistics data. This includes information on births, deaths, marriages, and divorces, which are essential for public health and policy planning. The NVSS is managed by the Centers for Disease Control and Prevention (CDC) and works with state and local health departments to gather accurate data. The data collected by the NVSS helps researchers, policymakers, and public health officials understand trends in population health and demographics. This information is crucial for addressing health issues, allocating resources, and improving community health outcomes across the nation.
