How old are you classified as a youth by the United Nations? What about middle age?

The United Nations World Health Organization has defined a new age group:

Young people under 44 years old, middle-aged people aged 45-59 years old, young people and elderly people aged 60-74 years old, elderly people aged 75-89 years old, and longevity people over 90 years old.

Before 1994, the international classification standard of population problems was three age groups: children from zero to 14; 15 to 64 years old is the labor force population; The elderly are over 64 years old (China is 60 years old).

Extended data:

1. In ancient times, according to the physiological characteristics of men's growth process, life was roughly divided into nine stages in ten years. They are "young", "weak", "strong", "old", "cave" and "period" respectively.

According to the new age classification determined by the World Health Organization, the upper age limit of young people has been raised to 44 years. From 1995 to 2000, the estimated world youth population increased from10.26 million to10.66 million, and its proportion in the global population decreased from 18. 1% to 17.6%. With the aging of the world population, it is predicted that by 2050, the proportion of young people in the global population will continue to drop to 13.2%, and the total number of young people aged 15-44 will be165438+76 million.
