Final answer:
Urban industrial families underwent significant changes during the Industrial Revolution, with shifts in gender roles, family size, and family organization.
Step-by-step explanation:
Urban industrial families underwent significant changes during the Industrial Revolution. With the shift from rural to urban areas, families became nuclear units consisting of parents and children, leading to a sense of isolation. Gender roles also changed, as previously women played important roles in agricultural or trade-based family businesses, but with industrialization, men and women started working separately in factories. In terms of marriage and family organization, industrialization led to a shift from the home being the workplace to families no longer being primary agents of production. Lastly, the urbanization brought about changes in family size and composition as people moved from rural to urban areas in search of job opportunities in factories.
