The 1910 census questionnaire was similar in design to that used in 1900. The most notable change was the late addition, at the behest of Congress, of a question concerning a person's "mother tongue." It was so late, in fact, that questionnaires for the census had already been printed. Information on "mother tongues" was to be added into "nativity" columns 12, 13, and 14. The following information, listed by column number, was gathered from each resident:

Indian Population Schedule
Enumerators of American Indians living on reservations or in family groups outside of reservations used a special modified schedule for the 1910 census which included an extra page of questions. Columns 1 through 32 were almost identical to the general population schedule. The only difference is that enumerators were instructed to mark "Ration Indian" in column 18 for occupation for those American Indians who did not work and were wholly dependent on government support. Those who work and received some support were to have their occupation listed, followed by the letter "R." Enumerators asked those listed on the Indian population schedule the following additional questions, listed by column number:
33. Tribe of this person
34. Tribe of this person's father
35. Tribe of this person's mother
36. Proportion of this person's lineage that is American Indian
37. Proportion of this person's lineage that is white
38. Proportion of this person's lineage that is black

41. If this person is living in polygamy, are his wives sisters?
42. If this person graduated from an educational institution, which one?

An American Indian was considered "taxed" if he or she was detached from his or her tribe and was living in the white community and subject to general taxation, or had been alloted land by the federal government and thus acquired citizenship.

45. Is this person residing on his or her own land?

Enumerators were to mark "Civ." (for "civilized") if the person was living in a log, frame, brick, or stone house, etc. and "Abor." (for "aboriginal") if the person was living in a tent, tepee, cliff dwelling, etc.
