Nonprofits face increasing pressure to compete in the market, while they must maintain their civic commitment. Focusing on the arts and cultural sector, this study conducts the first large-scale, comprehensive empirical measurement of nonprofits’ engagement in various roles. The article uses a previously validated 18-item role index to categorize nonprofits as primarily engaged in either civic or market functions, so that a subsequent regression analysis can identify the common characteristics of civically active nonprofit arts service organizations. The data come from (a) qualitative interviews with leaders of arts nonprofits, (b) a random national sample of more than 900 arts nonprofits, and (c) Internal Revenue Service (IRS) tax returns of the sample nonprofits. The findings suggest that civically active arts nonprofits have diverse networks, recognize civic engagement as the industry norm, and are consciously aware of their nonprofit status. The results suggest how nonprofits can balance their equally important market- and civic-oriented functions.
