ENTREPRENEURSHIP

Detailed explanation-1: -Population aging is largely caused by two demographic trends. Most obviously, people today are living longer than before. A second and less obvious cause of population aging is a decline in the birth rate.

Detailed explanation-2: -While this shift in distribution of a country’s population towards older ages – known as population ageing – started in high-income countries (for example in Japan 30% of the population is already over 60 years old), it is now low-and middle-income countries that are experiencing the greatest change.

Detailed explanation-3: -Starting in 2030, when all boomers will be older than 65, older Americans will make up 21 percent of the population, up from 15 percent today. By 2060, nearly one in four Americans will be 65 years and older, the number of 85-plus will triple, and the country will add a half million centenarians.

Detailed explanation-4: -The amount of aging the U.S. population will experience in the future depends on trends in mortality, fertility, and migration. In general, the lower the levels of fertility, mortality, and migration, the older the population will become.
