During the summer of 1975, a census survey of the membership of the Creek Nation was conducted to collect data on various selected social, educational, and economic characteristics of the tribal membership. Data were collected and analyzed on the household and individual family members residing in those households at the time. Data were obtained on: the household's geographic location by county, township, range, and section; household income; housing status (financing, renting); house structure (rooms, heating system, bathroom facilities, water source); tribal language usage; voter registration; social services utilized by the household; education; institutional enrollment; tribal affiliation; degree of Indian blood; employment patterns; occupational skills; job stability; job location relative to home residence; and organizations and persons used in emergencies. Using Creek Indian people who were familiar with the Nation, data were collected in eight counties: Creek, Hughes (including Seminole) McIntosh, Muskogee, Okfuskee, Okmulgee, Tulsa, and Wagoner (including Rogers and Mayes). Of the 1,888 households drawn from a master list, 1,225 usable questionnaires were returned for computer analysis. As requested by Creek Nation officials, this report presents only percentages and frequencies by category within each variable. Data for each variable are repeated three times under the following formats: all membership or households combined; urban vs. rural; and county-by-county. (NQ)
