What caused the structure of the family to change?Here is an example from the western world. In the early 1900s in the United States the divorce rate (i.e., the percent of legal endings compared to the number of marriages) began to rise, and the birthrate (i.e., the number of births per 100 or 1000 people) began to decline; in other words, couples stayed married for fewer years, and they had fewer children. Women often chose to get an education and take jobs outside the home. Decades later, the same things began to occur other industrialized countries, Today, they are happening in many of the developing nations of the world as well.
