How to understand demographic variables?

Demographic variables: including gender, age, nationality, education, health, income and relative status.

Such as birth rate, death rate, average reproductive age of women and so on. Cohort analysis is a continuous observation and analysis of a group of people who have a certain demographic event (such as birth, marriage and childbirth) at the same time. Further considering the limitations of the actual queue method, demography has also developed and applied the hypothetical queue analysis method.

Simultaneous analysis and cohort analysis are two basic statistical analysis methods unique to demography. Synchronous analysis is mainly to measure and describe population phenomena or events in a certain time and space, and explain their frequency and level. Most demographic indicators in demography belong to the same period.

Its characteristic is that the population events in a certain period are regarded as the corresponding events of the same population in different periods. Life table, birth table and marriage table, which play a special role in demographic analysis, are all compiled in this way, and special indicators such as population net productivity and average generation interval are also calculated on this basis.
