In America, older people rarely live with their adult children. But in many other cultures

children are expected to care 【C1】______ their aged parents. In some parts of Italy, the percentage of adult children who 【C2】______ with their parents 【C3】______ 65% to 70%. in Thailand, too, children are expected to look after their elderly parents; few Thai elderly live 【C4】______ . What explains these differences in living arrangements across cultures？ Modernization theory 【C5】______ the extended family to low levels of economic development. In traditional societies, the elderly live with their children in large extended family units for economic reasons. 【C6】______ with modernization, children move to urban areas, 【C7】______ old people after in 【C8】______ rural areas. Yet modernization theory can't 'explain why such households were never common in America or England, or why families in fully modernized Italy 【C9】______ a strong tradition of intergenerational living. Clearly, economic development alone cannot explain 【C10】______ living arrangements.

Another theory associated intergenerational living arrangements with inheritance 【C11】______ . In some cultures, the stem family pattern of inheritance overtakes. 【C12】______ this system, parents live with a married child, usually the oldest son, who then 【C13】______ their property when they die. The stem family system was once common in Japan, but changes in inheritance laws, 【C14】______ broader social changes brought 【C15】______ by industrialization and urbanization, have 【C16】______ the usage. In 1960 about 80% of Japanese over 65 lived with their children; by 1990 only 60% 【C17】______ — a figure that is still high 【C18】______ American standards, but which has been 【C19】______ steadily. In Korea, too, traditional living arrangements are 【C20】______ : the percentage of aged Koreans who live with a son declined from 77% in 1984 to 50% just 10 years later.
