In the specific calculation process, generally, all the people who have reached the legal school age in a region (for example, in China, they are generally 6-7 years old) are taken as the base, and according to their respective education stages, the sum of their years of education is calculated according to a certain weight, and then divided by the total population of this region, the average years of education in this region can be obtained.
The specific weight is usually as follows:
* College degree or above is calculated as 16 years.
* high school 12 years.
* Nine years of junior high school.
* 6 years of primary school.
* Illiteracy is 0 years old.
It should be noted that this calculation assumes that everyone can get the years of education at each stage after completion, but in fact, different people may have different years of education for various reasons. Therefore, this method can only provide a rough measurement result, and more detailed social investigation and research are needed if more accurate data are to be obtained.
