Age Structure

Age Structure

Like other postindustrial countries, Japan faces the problems associated with an aging population. In 1989, only 11.6 percent of the population was sixty-five years or older, but projections were that 25.6 percent would be in that age category by 2030. That shift will make Japan one of the world's most elderly societies, and the change will have taken place in a shorter span of time than in any other country.

This aging of the population was brought about by a combination of low fertility and high life expectancies. In 1993 the fertility rate was estimated at 10.3 per 1,000 population, and the average number of children born to a woman over her lifetime has been fewer than two since the late 1970s (the average number was estimated at 1.5 in 1993). Family planning was nearly universal, with condoms and legal abortions the main forms of birth control. A number of factors contributed to the trend toward small families: late marriage, increased participation of women in the labor force, small living spaces, and the high costs of children's education. Life expectancies at birth, 76.4 years for males and 82.2 years for women in 1993, were the highest in the world. (The expected life span at the end of World War II, for both males and females, was fifty years.) The mortality rate in 1993 was estimated at 7.2 per 1,000 population. The leading causes of death are cancer, heart disease, and cerebrovascular disease, a pattern common to postindustrial societies.

Public policy, the media, and discussions with private citizens revealed a high level of concern for the implications of one in four persons in Japan being sixty-five or older. By 2025 the dependency ratio (the ratio of people under fifteen years plus those sixty-five and older to those aged fifteen to sixty-five, indicating in a general way the ratio of the dependent population to the working population) was expected to be two dependents for every three workers. The aging of the population was already becoming evident in the aging of the labor force and the shortage of young workers in the late 1980s, with potential impacts on employment practices, wages and benefits, and the roles of women in the labor force. The increasing proportion of elderly people in the population also had a major impact on government spending. As recently as the early 1970s, social expenditures amounted to only about 6 percent of Japan's national income. In 1992 that portion of the national budget was 18 percent, and it was expected that by 2025, 27 percent of national income would be spent on social welfare.

In addition, the median age of the elderly population was rising in the late 1980s. The proportion of people aged seventy-five to eighty-five was expected to increase from 6 percent in 1985 to 15 percent in 2025. Because the incidence of chronic disease increases with age, the healthcare and pension systems, too, are expected to come under severe strain. The government in the mid-1980s began to reevaluate the relative burdens of government and the private sector in health care and pensions, and it established policies to control government costs in these programs. Recognizing the lower probability that an elderly person will be residing with an adult child and the higher probability of any daughter or daughter-in-law's participation in the paid labor force, the government encouraged establishment of nursing homes, day-care facilities for the elderly, and home health programs. Longer life spans are altering relations between spouses and across generations, creating new government responsibilities, and changing virtually all aspects of social life.
