Administrative History
Registration of births in New York State outside of New York City began January 1, 1881, under supervision of the State Board of Health (now Department of Health). A birth certificate issued by a local registrar of vital statistics contained accurate, verifiable information on an individual's name, and date and place of birth. That information was useful for legal proof of age. A 1913 law made a certified copy of a birth certificate "prima facie evidence of age," for purposes of school attendance and employment certificates ("working papers") issued to minors.
