## 1930

For the 1930 census, the population questionnaire was basically the same as it had been in 1910 and 1920.

The biggest change was in racial classification.  Enumerators were instructed to no longer use the "Mulatto" classification.  Instead, they were given special instructions for reporting the race of interracial persons.

A person with both White and Black lineage was to be recorded as Black, no matter fraction of that lineage.  A person of mixed Black and American Indian lineage was also to be recorded as Black, unless he was considered to be "predominantly" American Indian and accepted as such within the community.

A person with both White and American Indian lineage was to be recorded as an Indian, unless his American Indian lineage was very small and he was accepted as white within the community.  In fact, in all situations in which a person had White and some other racial lineage, he was to be reported as that other race.  Persons who had minority interracial lineages were to be reported as the race of their father.

For the first and only time, "Mexican" was listed as a race.  Enumerators were to record all persons who had been born in Mexico or whose parents had been born in Mexico and who did not fall into another racial category as "Mexican."

Enumerators collected the following information, listed by column number:
