The breadwinner model is a paradigm of family centered on a breadwinner, "the member of a family who earns the money to support the others." Traditionally, the earner works outside the home to provide the family with income and benefits such as health insurance, while the non-earner stays at home and takes care of children and the elderly. The breadwinner model largely arose in western cultures after industrialization occurred. Before industrialization, all members of the household—including men, women, and children—contributed to the productivity of the household. Gender roles underwent a re-definition as a result of industrialization, with a split between public and private roles for men and women, which did not exist before industrialization.
