Overview

The CDC's 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.
• Identify disparities in health status and use of health care by race/ethnicity, socio-economic status, region, and other population characteristics.
• Document access to and use of the health care system.
• Monitor trends in health status, associated risk factors and health care delivery.
• Support biomedical and health services research.
• Provide data to support public policies and programs.
• Evaluate the impact and effectiveness of health 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.
