Dating Assortativity in Japan: Evidence from a Retrospective Survey

Abstract

We conduct a series of retrospective surveys to understand the evolution of dating assortativity in Japan. In the surveys, we ask about age, income, and employment type of our respondents and their dating partners. We find that the age assortativity has increased over the past ten years or so among age groups 25-29 and 30-34. The income assortativity has been stable, but we find some evidence for an increasing trend for the employment-type assortativity among regular employees.
