Federal Censuses of 1850 to 1940 Census Birth Year Reference
Below, you will find a chart containing the approximate birth years for age listings on the census. Please remember, that before 1850 the census information on age was vague. To read this chart: first, find the census year then locate the age shown in the census. Note that in 1900, the algorithm used by the enumerators often produced a one year error in birth year.
