The goal of this study was to develop a demographic profile of food co-op shoppers and to assess the relationship between policy importance ratings and two measures of shopper involvement. A survey measuring co-op shopper demographic characteristics, ratings of co-op environment and ratings of the importance of 13 co-op policies was completed by 283 food co-op shoppers in the fall of 1983 at the Food Conspiracy Co-op in Tucson Arizona. Overall, the strongest distinction between working members and non-members was a tendency for members to spend more at the food co-op. The two groups were similar demographically and similar in their ratings of the quality of food co-op atmosphere. Both groups rated range of co-op policies as important factors in store selection. These co-op policies were equally important to both members and non-members, and the importance ratings were largely unaffected by length of involvement with the organization.
