NARA M595. Most rolls include the English and/or Indian name of the person, roll number, age or date of birth, sex, and relationship to head of family. Beginning in 1930 the rolls also show the degree of Indian blood, marital status, ward status, place of residence, and sometimes other information. Only persons who maintained a formal affiliation with a tribe under Federal supervision are listed on these census rolls. There is not a census for every reservation or group of Indians for every year.
