What are the ages of people? How to divide the age group of people

Calendar age: People's calendar age increases equally with the passage of time, no matter how good you are at maintenance, and no matter how well you understand life, in the face of the growth of calendar age, anyone's years are "helpless flowers to fall".

Physical Age: Due to genetic factors and differences in maintenance, people with the same calendar age will have very different physical appearances and ages.

Biological age: people's biological age is not necessarily the same, some people are old and sick; Some people are immortal and youthful.

Mental age: People are not equal before their mental age. Some young people are much older psychologically, sluggish, conservative, and rigid; Some people are still childlike even in their twilight years, and it is rare to be nonsense, "Lao Ji is in the middle of his life, and his ambitions are thousands of miles."

Social age: Social age is directly proportional to people's accumulation of experience, knowledge, and talents. Some people are old, but they are naïve and ridiculous in doing things; Some people are "small and big" and calculating.

A wide range of activities, experienced, knowledgeable, talented, eloquent, thoughtful, and resourceful are the hallmarks of a high age in society.

How should the age groups of human beings be divided?

For example, what is the division between young and middle-aged and old?

The United Nations World Health Organization has conducted a detailed study and evaluation of the global human body, especially the quality and average life expectancy of the human body have been re-measured, and new regulations have been made for the division of human ages

Minors: 0 to 17 years old;

Young people: 18 to 65 years old;

Middle-aged: 66 to 79 years old;

Seniors: 80 to 99 years old.

The aging period of human beings has been postponed for many years, which is mainly due to the study of people's mental health and anti-aging awareness, with the continuous extension of human lifespan, so the division of this age group is also constantly extended.

There are four main age groups in China, namely the youth group, the young and middle-aged group, the middle-aged group, and the elderly group. Internationally, it is usually divided according to the division of 0 14 years old, 15 64 years old, and 65 years old.

There are four types of human ages, do you know which four they are?

According to the new age segment, a person's life is divided into six age groups:

Newborn) - 6 years old for infants;

12 years old for children;

6. > 69 years old is the elderly.

<> divided into four age groups in China by age, namely youth group (under 29 years old), young and middle-aged group (30-39 years old), middle-aged group (40-49 years old) and middle-aged and elderly group (over 50 years old).

Childhood is under 12 years old, and over 12 years old is called the juvenile general horn age.

At the age of 20, the weak crown is a young man, and some people think that after 18 is a young man. When he stands at 30, he enters middle age, and when he is not confused at 40, he is called the prime of life. 50 and knowing the destiny of heaven, of course, is considered old.

60 flowers, 70 ancient rare, 80, 90 years old, 100 years old.

Internationally, the population is usually grouped unequally from 0 14 years old, 15 64 years old, and over 65 years old, which are called juvenile population, prime population, and elderly population, and the juvenile population coefficient is calculated based on the total population.

The coefficient of the population in the prime of life and the coefficient of the elderly population are also calculated based on the number of the population in the prime of life, that is, the dependency coefficient = (juvenile population + elderly population) The population in the prime of life, and the population in the age group of 15 to 24 years old is also called the youth population in the world.
