TDR takes great care to provide complete citations for all sources used in compiling our data so that our clients may in turn cite these sources appropriately. All TDR databases cite surveys published by the National Center for Health Statistics (NCHS) in Hyattsville, Maryland. In addition, the Incidence and Prevalence Database (IPD) provides Article Reviews based primarily on publications from the peer-reviewed medical literature.

For details on citing NCHS databases, consult "How to Cite NCHS Publications” at the NCHS website.
