United States – According to the U.S. Census Bureau, the number of people aged over 65 will be more than double by 2040 from 506 million in 2008 to 1.3 billion.

According to this study, the elderly will outnumber children below 5 years of age in the next 10 years. It would be a first in the history of Humanity. The rapidly aging global population would increase the number of people over 65 years old by 160% by 2040 and those over 80 years by 233%.

The baby-boom generation, including all births after the war, is becoming the papy-boom generation. The large number of children born since 1945 is aging well and medical advances are conducive to better health. But in parallel, the fertility rate has declined, children born today do not renew the generations that precede them.

If this aging affects the developed countries like Europe and the United States, developing countries like Asia and Latin America are also victims of this phenomenon. If Europe is the continent with most “old”, Africa is the youngest.

In Asia, China, where there is one child policy, shelters the greatest number of elderly: 106 million in 2008. However, proportionally, Japan has the large number of older people, with 22% of inhabitants over 65 years age.
