Positive assortative mating for education and social position has been widely reported in a number of countries, but very few studies have tested whether or not educational or social class homogamy is related to differential fertility.
This study examined the relationship between educational and social class assortative mating and fertility in a British national cohort.
The analyses were based on 7452 husband-wife pairs from the British National Child Development Study (NCDS).
The mean fertility was 3.22 children per couple; the number of children significantly increased from higher to lower social classes and from the more educated to the less educated. The extent of assortative mating for social class and educational level was related to fertility; as educational assortative mating decreased so did the average number of children, whereas the opposite trend was observed for social class. When assortative mating for education and social class were considered together, educational assortative mating was the more significant predictor of the number of children and educationally homogamous couples had higher fertility independent of their social class assortative mating.
The relationship between assortative mating and fertility for education and social class appeared to be acting in the opposite direction.
在许多国家，教育程度和社会地位的正向择偶已被广泛报道，但很少有研究检验教育或社会阶层的同质性是否与生育差异有关。
本研究探讨了英国一个全国性队列中教育程度和社会阶层择偶与生育之间的关系。
分析基于英国全国儿童发展研究（NCDS）中的7452对夫妻。
平均每对夫妻生育3.22个孩子；孩子数量从社会阶层较高到较低以及从受教育程度较高到较低显著增加。社会阶层和教育水平的择偶程度与生育有关；随着教育择偶程度降低，平均孩子数量也降低，而社会阶层则呈现相反趋势。当同时考虑教育和社会阶层的择偶时，教育择偶是孩子数量更显著的预测因素，教育同质的夫妻生育率更高，且独立于他们的社会阶层择偶情况。
教育和社会阶层的择偶与生育之间的关系似乎呈相反方向。
