Congress mandated that another unemployment census be conducted in 1937.
This special census was voluntary; postal carriers delivered a form to every residential address in the country and those who were unemployed were expected to fill it out and mail it back.
This special census is noteworthy because it was an opportunity for Census Bureau to experiment with statistical sampling.
Two percent of households were delivered a special census questionnaire whose results were used to test the accuracy of the larger census.
Age at First Marriage
A question that was new to the 1930 census that is useful to genealogy research was the age of the person at their first marriage.
This information can be cross referenced with other records to gain more useful information about the family.
Although some the family status of some people may have changed during the year, they were expected to list their status as of the day that the census began.
For example, if a child was born in Alaska after October 1, 1929, he or she should not be listed on the 1930 census.
Historical Considerations of the 1930 Census
Effects of World War I
Due to boundary changes that occurred during World War I, some people weren’t sure how to record their country of origin because the status of the country had changed.
Countries that were affected by the boundary issue were Austria-Hungary, Germany, Russia, Turkey and Bulgaria.
Enumerators were instructed to write down the city, state, province or region of birth for the resident or their parents if the resident or their parents were born in any of the effected countries.
The 1930 census listed Native American (referred to as “Indian”) inhabitants of reservations within the schedules for the general population.
However, each Native American’s parental records were recorded differently. On the mother’s side, tribe was recorded. On the father’s side, degree of Indian blood was recorded.
Reporting Births & Deaths
Children that were born between the official start date of the census and the actual day of enumeration were not included.
Individuals that were alive on the official start date of the census but deceased by the actual day of enumeration were included.
Servicemen were not recorded with their families in the 1930 census; they were treated as residents of their duty posts. If you’re looking for someone in the military, you should not assume they will be listed in their home town.
