The National Center for Health Statistics (NCHS) is the principal federal agency within the U.S. Centers for Disease Control and Prevention (CDC) responsible for collecting, analyzing, and publishing data on the health of the U.S. population. NCHS produces official statistics on topics including mortality and life expectancy, births and fertility, disease prevalence, health behaviors, health insurance coverage, and health care utilization through surveys (such as NHIS, NHANES), vital statistics systems, and administrative data.

The NCHS website provides access to data tables, interactive tools, downloadable microdata and summary datasets, reports, and technical documentation. Its statistics are widely used by policymakers, public health professionals, researchers, and other stakeholders to monitor health trends, assess disparities, evaluate public health programs, and inform evidence-based decisions in health policy and planning.

NCHS Data and Analysis Tools is the National Center for Health Statistics’ collection of interfaces and systems for accessing U.S. health data. It includes query tools, analysis systems, and visualization platforms for topics such as mortality, disease prevalence, health surveys, and vital statistics. These tools support researchers, public health professionals, and policymakers in exploring and analyzing official health data.

NCHS Data Dashboards, Visualizations, and Query Systems provides interactive health data tools from the National Center for Health Statistics. It includes dashboards and query interfaces for exploring survey results, vital statistics, health indicators, and population health trends. These resources help users visualize and analyze official health data for research, public health planning, and policy assessment.
