National Center for Health StatisticsNCHS, run by the Centers for Disease Control (CDC), hosts a large volume of information covering every aspect of health in the United States. More than just information about diseases is available: mortality and natality, exercise, marriage, injury, and access to health care are included. NCHS fast facts page (www.cdc.gov/nchs/fastats/) makes beginning research relatively straight forward. Additionally most NCHS and CDC web pages have access to an A to Z topic list at the top of the page.
