How (and Why) Online Dating Experiences Differ across American Cities

Abstract

Social scientists have long shown that city-level differences in patterns of assortative mating, marriage rates, and non-marital childbearing are associated with labor market conditions and partnering opportunities. But it is difficult to observe the interactions that give rise to romantic outcomes in different places. As a result, we know little about whether, how, and why romantic experiences differ across cities. In this talk, I present results from a new study that uses rich activity data from a large, U.S. dating website to explore how population composition interacts with mate-seeking behavior to shape men and women's online romantic experience. Building on insights from psychology and behavioral ecology, I focus on two distinct classes of behavior: choice/preferences and competition. I show that mate seekers in different U.S. cities have divergent strategies for mate pursuit: they differ in their preferences, pickiness, and intensity of competition. In the final section, I focus on individuals who appear to change markets, to assess whether and how changing contexts is associated with a change in strategies for mate pursuit. This study represents a novel quantitative effort to show how men and women's mate-seeking behaviors differ systematically with their opportunities.
