Family formation trends and patterns of women's work trajectories in South Korea: determinants and cohort differences

We use sequence analysis on data from the Korean Labor & Income Panel Study (1998-2019) to investigate trajectories of women's labour market participation in the eight years after first childbirth. We pay special attention to the type of employment through which mothers participate in the labour market, distinguishing between regular full-time employment, non-regular employment, self-employment, and non-employment. After creating employment sequences, we use cluster analysis to reveal patterns of employment trajectories and average marginal effects derived from multinomial logistic regression to identify women's characteristics on the distinct trajectories. We find that women of younger cohorts are less likely to solely focus on family and childcare in the years after childbirth. However, their chances of steady work in regular jobs did not increase. Instead, they are more likely to be on unsteady pathways, combining childcare with regular or non-regular jobs. Our results suggest that increases in females' employment might be partly attributed to mothers' higher probability to obtain precarious non-regular work.
