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.  These health statistics allow us to:

  • Document the health status of the U.S. population and selected subgroups.
  • Track impact of major policy initiatives including the Affordable Care Act.
  • Identify disparities in health status and use of health care by race/ethnicity, socio-economic status, other population characteristics and geographic region.
  • Document access to and use of the health care system.
  • Monitor trends in health indicators.
  • Support biomedical and health services research.
  • Provide data to support public policies and programs.


Health Topics Addressed by NCHS

NCHS produces data on a wide range of health indicators such as:

  • Health insurance coverage and its relationship to access and utilization of health care services.
  • Prevalence of health conditions such as obesity and overweight, cholesterol, hypertension, HIV status, and smoking among the U.S. population.
  • Exposure to environmental chemicals.
  • Nutrition and physical activity.
  • Growth charts to monitor the development of children.

  • Injuries and disabilities and their impact on health status and functioning.
