POPULATION AGING PHENOMENON
Abstract:
There were 600 million people aged 60 and over in 2000; there will be 1.2 billion by 2025 and 2 billion by 2050. Today, about two thirds of all older people are living in the developing countries; by 2025, it will be 75%. In the developed countries, the very old (age 80+) is the fastest growing population group. Women outlive men in virtually all societies; consequently in very old age, the ratio of women/men is 2:1. As populations age and live longer, chronic diseases become increasingly prevalent. Older persons with complex pathologies and conditions will require multiple sources of care to meet their health care needs. They will need to depend on a health care delivery systems that can adequately address and reliably serve their multiple needs.
