These data consist of a sample of the legitimate live births occurring in the United States in 1972. To gather the data, a sample of birth certificates was selected and questionnaires were mailed to the mothers, their physicians, and the hospitals where the births took place. The purposes of the survey were to assess the accuracy of birth certificates, to examine trends in births compared to earlier years, and to enlarge the range of information included in the vital registration system.
