Was the Nuclear Family a Historical Accident, Asks David Brooks

Through the early parts of American history, most people lived in what, by today’s standards, were big, sprawling households. In 1800, three-quarters of American workers were farmers. Most of the other quarter worked in small family businesses, like dry-goods stores. People needed a lot of labor to run these enterprises. It was not uncommon for married couples to have seven or eight children. In addition, there might be stray aunts, uncles, and cousins, as well as unrelated servants, apprentices, and farmhands. (On some southern farms, of course, enslaved African Americans were also an integral part of production and work life.)

Steven Ruggles, a professor of history and population studies at the University of Minnesota, calls these “corporate families”—social units organized around a family business. According to Ruggles, in 1800, 90 percent of American families were corporate families. Until 1850, roughly three-quarters of Americans older than 65 lived with their kids and grandkids. Nuclear families existed, but they were surrounded by extended or corporate families….

Over the course of the 18th and 19th centuries, industrialization and cultural change began to threaten traditional ways of life. Many people in Britain and the United States doubled down on the extended family in order to create a moral haven in a heartless world. According to Ruggles, the prevalence of extended families living together roughly doubled from 1750 to 1900, and this way of life was more common than at any time before or since.
