Recent studies show that temporary workers postpone family formation transitions, but it remains unclear whether this effect is due to the lower income or the stronger perceptions of job insecurity that go with a temporary contract. To address this question, we link data from a large-scale survey among Dutch employees to longitudinal population register data on marriage and first births. Logistic regression models estimate the effects of temporary employment on marriage and first birth, and mediation analyses assess to what extent these effects are explained by income and perceptions of job insecurity. Results show that temporarily employed women delay first birth. There is also some evidence that temporarily employed men postpone marriage and first birth. These effects are partly explained by income, which increases marriage and first birth rates among men and women alike. Perceptions of job insecurity generally had little effect on family formation, although higher marriage rates were found among women who experienced affective job insecurity. Overall, this shows that it is their low income rather than their feelings of insecurity about future employment that explains why temporary employees postpone family formation.

临时就业和家庭组建：收入或不安全效应？

最近的研究表明，临时工推迟了家庭组成的过渡，但尚不清楚这种影响是由于收入较低还是临时合同带来的工作不安全感更强。为了解决这个问题，我们将荷兰雇员的大规模调查数据与婚姻和头胎的纵向人口登记数据联系起来。逻辑回归模型估计临时就业对婚姻和头胎的影响，中介分析评估这些影响在多大程度上可以用收入和对工作不安全感的看法来解释。结果表明，临时就业的妇女推迟第一次生育。还有一些证据表明，临时就业的男性推迟结婚和第一次生育。这些影响部分可以用收入来解释，这增加了男性和女性的结婚率和首次生育率。对工作不安全感的看法通常对家庭形成几乎没有影响，尽管在经历过情感工作不安全感的女性中发现了更高的结婚率。总体而言，这表明是他们的低收入而不是他们对未来就业的不安全感解释了为什么临时雇员推迟了家庭组建。
