The National Center for Health Statistics (NCHS) is part of the Centers for Disease Control and Prevention (CDC). The Center's website is a rich source of information about America's health. As the Nation's principal health statistics agency, the Center compiles statistical information to guide actions and policies to improve citizens' health. It is a unique public resource for health information — a critical element of public health and health policy.
Working with partners throughout the health community, the Center uses a variety of approaches to efficiently obtain information from the sources most able to provide information. It collects data from birth and death records, medical records, interview surveys, and through direct physical exams and laboratory testing. NCHS is a key element of our national public health infrastructure, providing important surveillance information that helps identify and address critical health problems.
