  • What Is Old?In the U.S. and much of the world, old age has come to be defined as beginning at age 65.As the number older people increase there are changes in the organization of society. Societies react differently to older than to younger people, producing the social changes that accompanying population aging.

  • How Many Older People Are There?As of 2004, there were 462 million people in the world aged 65 and older, according to United Nations estimates.The older population accounts for 7% of the total world population but this percentage varies from one part of the world to another.

  • Number of Older People is Growing Rapidly

  • Where are the Older Populations?As of 2000, 14.7% of Europes population was 65 and older.It is projected that by 2050 that will have risen to 27.9%.By 2050 we can expect that 10% of the population in every region of the world except sub-Saharan Africa will be aged 65 and older.

  • Where Are the People Who Are 65 and OlderEurope had more than 100 million older people in 2000.By 2025, Europes older population will number nearly 150 million.There will likely be nearly a quarter of a billion in Eastern Asia, and more than 150 million in south central Asia (which includes India).

  • Physical AgingPhysiological changes that take place tend to be steady but gradual through adulthood into old age.The more complex the bodily function, the more rapid its rate of decline.Individuals age at different rates, and different tissues and systems within one person may also age at different rates.

  • Physical AgingAging brings with it a lowered ability to respond to stress.Aging brings a diminished ability to resist disease.

  • Modernization:Status of the ElderlyThe status of older persons was relatively high in premodern, agrarian societies.Things began to change as societies modernized and people began to live longer. A high level of mortality increases the odds that a younger person will be able to inherit the family business, or move into a position in society vacated by the deaths of other people.
