Using data from the TYP (Taiwan Youth Project) panel survey, we examine factors associated with early marriages in Taiwan and the subsequent risks for negative outcomes in family life and career trajectories. About 7% of Taiwanese people marry early, that is, before the age of 28 years. Among those who marry early, more than 60% report the birth of a child within the first 8 months of marriage (i.e., they form postconception “shotgun” marriages). Compared with the never married respondents, individuals in both preconception and postconception early marriages are likely to come from families of low socioeconomic status. Nonworking young adults and those experiencing parental divorce or parental death during adolescence are at higher risk of entering postconception marriages than those remaining single. Particularly for nonemployed young people and those from lower socioeconomic status background, early marriage means taking on adult responsibilities in a disadvantaged state.
