The standard certificates have been the principal means for achieving the uniformity in information on which national vital statistics are based. The U.S. Bureau of the Census developed the first standard certificates for the registration of vital events—births and deaths—in 1900. To date there have been 11 revisions of the Standard Certificate of Live Birth, 10 revisions of the Standard Certificate of Death, 7 revisions of the Standard Report of Fetal Death (formerly Stillbirth), 3 revisions of the Standard Certificates of Marriage and of Divorce or Annulment, and 1 revision of the Standard Report of Induced Termination of Pregnancy.
