"Extended families have never been the norm in America; the highest figure for extended-family households ever recorded in Americanhistory is 20 percent. Contrary to the popular myth that industrialization destroyed "traditional" extended families, this high point occurred between 1850 and 1885, during the most intensive period of early industrialization.
