This article contributes to research on co-production in non-profit organizations. By comparing co-production in public, for-profit, and non-profit organizations, similarities and differences between types of organizations are identified. The empirical material is delimited to homes for the elderly in Sweden, collected by a questionnaire, and combined with secondary data. In terms of main results, most analyses revealed neither any differences in the co-production of welfare between types of organizations nor correlations with size of the homes. However, the differences that were identified indicate that managers and residents in non-profit homes value and participate in co-production to a higher degree than managers and residents in public and for-profit homes. These results support assumptions and results from previous research, including the finding that co-production in different types of organizations varies, and that co-production could be more widespread in non-profit organizations.
