Sport consumer behavior researchers have developed a robust understanding of how and why people consume sport, and the consequences of consumption. There has been little reflection, however, on the settings or populations used to study consumers and develop theory. In acknowledging the importance of diversity, equity, and inclusion to advance both theory and practice, the authors conducted a scoping review of diversity in sport consumer behavior research, focusing on four sport management journals. The review revealed a widespread lack of diversity, with most studies focusing on men’s sport in highly commercialized settings. Furthermore, study participants often identify as White men, middle-aged or young, educated, and with at least some disposable income. Leveraging an institutional work lens, the authors address taken-for-granted norms that may have contributed to these trends and propose solutions.
