The terminology of the PFC Thesaurus is based on the literature collected and stored in POPINFORM by the Population Information Program. In the selection of terms and phrases, every effort was made to coordinate the vocabulary with MeSH, FMT and the PFP Thesaurus. Numerous other references were consulted for terms, definitions and scope notes including the Karolinska's Human Reproduction Thesaurus, the United Nations' Multilingual Demographic Dictionary, Dorland's Medical Dictionary, the OECD Macrothesaurus, and the International Demographic Data Directory of the International Statistical Programs Center of the U.S. Bureau of the Census.
