I heard that there were supplemental questions asked on the 1940 Census. Will I find information about my family in the supplemental questions?
The supplemental questions were asked for the people listed on two lines on each page of the census schedules (about a five-percent sample of the census). The supplemental schedule asked:
- The place of birth of the person's father and mother;
- The language spoken in earliest childhood home;
- If the person was a veteran;
- If the person was a child whose father was a veteran;
- If the veteran served in a specific war or in peacetime military service;
- For persons 14 years old or older, if the person had a Social Security number or had deductions for Federal Old Age Insurance or Railroad Retirement made in 1939;
- The person's usual occupation (not just what they were doing the week of March 24-30, 1940, when the census was taken); and
- For all women who were or had been married, if the woman had been married more than once, her age at first marriage, and the number of children born.
