NCHS, Explained: What Is The National Center For Health Statistics
The National Center for Health Statistics, or NCHS, is the United States government's principal health statistics agency and the main federal source for official data about Americans' health, births, deaths, diseases, and health care use. It sits within the Centers for Disease Control and Prevention and was created in 1960 to bring together the nation's vital records and health survey systems into one statistical center.
What NCHS does
NCHS collects, analyzes, and publishes health data that federal, state, local, and academic users rely on to track trends and guide policy. Its statistics help answer questions such as how long people are living, what they are dying from, how often chronic disease appears, and how health indicators differ across age, sex, race, geography, and income.
The agency is best known for making health data usable, comparable, and public. In practice, that means it turns raw information from surveys, birth and death certificates, and health care records into national statistics that can be used for research, reporting, and planning.
Why it matters
Health policy depends on reliable numbers, and NCHS provides many of the baseline measures used to understand the nation's health. Public health agencies use its data to identify disparities, monitor outbreaks or long-term trends, and evaluate whether interventions are working.
Researchers, journalists, and health systems also depend on NCHS because it is a trusted source of standardized data rather than opinion or estimates from a single institution. That makes it one of the most important statistical references in U.S. health reporting.
Core data sources
NCHS does not rely on a single dataset; it combines several large programs and record systems to build a broader picture of health in the United States. Those sources include national surveys, vital records, and clinical or administrative data.
- Vital statistics, including birth and death records.
- National health surveys, which collect self-reported and measured health information.
- Health care data, used to study use of services, access, and outcomes.
- Public health indicators, which help track trends over time and across populations.
How the agency is used
NCHS statistics support a wide range of decisions, from federal health planning to local program design. For example, mortality data help track leading causes of death, while survey data can reveal obesity rates, vaccination patterns, disability prevalence, or mental health trends.
Decision-makers often use NCHS figures to compare places and populations, since the agency's methods are designed for national consistency. That standardization makes it easier to compare one year to the next, or one region to another, without mixing incompatible data sources.
Historical context
NCHS was formed in 1960 by combining the National Office of Vital Statistics and the National Health Survey, reflecting a broader federal effort to unify health measurement under one statistical authority. That origin matters because it explains why the agency covers both births and deaths as well as population health surveys.
Today, it remains part of the CDC and is widely described as the nation's principal health statistics agency. In budget and institutional terms, it is one of the major federal statistical agencies, with one source describing an annual appropriation of roughly $187 million and another noting combined budget lines around $160 million.
What it is not
NCHS is not a hospital, not a research university, and not a treatment provider. It does not directly diagnose patients or deliver care; instead, it produces the official statistics that others use to understand the health system.
That distinction is important because people sometimes confuse data producers with care providers. NCHS exists to measure health, not to administer medical services.

How to think about it
A useful way to understand NCHS is to think of it as the federal system's statistical backbone for health. It gathers the numbers that make public health visible, then packages those numbers so they can be used by policymakers, researchers, and the public.
For anyone reading a health report, seeing NCHS as the source usually signals that the data are official, standardized, and intended for broad public use. That is why the agency appears so often in discussions of mortality, chronic disease, health disparities, and national health trends.
