This study uses National Sports and Society Survey (N = 3,993) data and regression analyses to investigate the racial/ethnic diversity of sport participation experiences, perceptions of the impact of one’s athletic experiences, and beliefs about the effectiveness of sports in bringing different racial/ethnic groups together. We find that people overwhelmingly believe that sports bring different racial/ethnic groups together. Also, most individuals believe that their athletic experiences improved their understanding of people of other races and backgrounds. Although racial/ethnic diversity in sport seems to matter, subjective perceptions of the effects of one’s athletic experiences on understanding people of other races and backgrounds are more closely connected to one’s general beliefs about sports bringing different racial/ethnic groups together.
