Census Birth Date Calculator
To use the birth date calculator:
  • Enter the date the census was taken
  • Enter the age of the person at census time
  • Click the Add to List button
  • Enter date/age pairs from other census years
  • The date range for each entry is listed, as well as the overall birth range

The Calculated Birth Range is the range of possible birth dates, based on the individual census entries.
