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.
