How to know the total number of residents and the age distribution of the population in a residential area?

To understand the total number of residents and the age distribution of the population in a community, the following methods can be adopted:

1. Visit the residential property: the property will keep records of all households in the residential area, so that you can know how many households there are in this residential area and the age range of the heads of households. Through the age range of the head of household, we can indirectly know the total number of residents and the age distribution of the population in this community.

2. Survey statistics: For those who want to know more about the population of each household, they can take the form of household survey and record the population and age of each household one by one. This method may take more time and effort, but it is very effective for obtaining accurate data.

3. Refer to relevant reports: If there are some relevant research reports or census data, you can refer to these reports to understand the total number of residents and the age distribution of the population in this community.

It should be noted that no matter which way you obtain data, you need to respect personal privacy and abide by relevant laws and regulations.
