Assortative Mating and the Industrial Revolution: England, 1754-2021

Using a genealogical database of 447,000 people in England 1600-2025, as well as 1.7 million marriage records 1837-2021, Professor Gregory Clark of the University of Southern Denmark and his co-author estimate assortment by social status in marriage. They find the underlying correlation of status between groom and bride in England is remarkably high at 0.8, and unchanged 1754-2021. Even before formal education and occupations for women, grooms and brides matched tightly on educational and occupational abilities. In this Quantitative History Webinar, Gregory will show further that women contributed as much as men to most child outcomes. This implies strong marital sorting substantially increased the variance of social abilities in pre-industrial England. Other pre-industrial marital systems typically involved much less marital sorting. Thus, the development of assortative marriage in north-west Europe may help explain the location and timing of the Industrial Revolution, through its effect on the supply of those with upper-tail abilities.
