How people meet new friends changes throughout life in ways that change the potential for diverse friendships. This study presents results from the first U.S. survey with data on how respondents met their friends, specifically the two nonfamily friends they most often socialize with. The most common sources of new friendships shift across life from the dominance of schooling during youth, to the centrality of work in midlife, to neighbors and voluntary groups in later life. Educational homophily peaks for friendships made in midlife, and is strongest for friendships made in higher education and at work. Racial homophily generally declines as people age but is lowest for men in midlife, while decreasing later for women. Friendship sources largely account for life course changes in racial homophily, but not educational homophily. The racial homophily induced by friendship sources also changes as people age, but in different ways for women and men.
