Birth Date Estimator
Estimate a birth year from a recorded age on a census or other dated record.
Census ages are often estimates. Always check slightly wider ranges (e.g. +/-2 years) when searching for birth records.
Why Estimate?
Historical records often list an age rather than a birth date. Because you don't know if the person's birthday had happened yet in that year, the birth year is usually ambiguous.
