This study explores the factors associated with economic gender gaps emerging in marital and post-divorce life, using the fourth survey of the National Family Research of Japan (NFRJ18). The survey design is comparable to the preceding three surveys (NFRJ98, NFRJ03, NFRJ08), allowing us to describe long-term trends. The primary variable considered was annual equivalent income, to determine respondents' living standard. The findings are as follows. (1) Equivalent income is lower for women than for men. (2) This gender gap is mainly attributed to the differences among divorced people. (3) The gender gap among divorced people narrowed in the early 2000s, but has widened recently. (4) Four factors have strong effects on gap creation: education, regular employment, co-residing with children, and remarriage. (5) These effects are broadly consistent with the results from the NFRJ98-NFRJ08 data, but some changes are observed in NFRJ18. These findings can be located in the debate on the social institution of marria ge and divorce, contributing to how they create inequality and which reform is effective to eliminate the gender gap.
