Definition
Average population at each time point in a certain period
The average population is a comprehensive indicator that comprehensively reflects the general level of the total population in a certain period.Theoretically, the accurate calculation method of the average population should be the sum of the daily population, divided by the corresponding calendar days.The smaller the time interval, the more accurate the average population.However, in actual statistical work, it is impossible to obtain daily population figures.Therefore, the average population referred to in statistics is the approximate value of the average population calculated on the premise that the population in this period changes evenly.For a long time, we have often carried out population statistics according to household registration, so we are calculating the per capitagross domestic productThe average registered population is mostly used for calculation.
