Why does the census have to go to households? Is this a "legal" break-in?

/kloc-children under the age of 0/6 can apply for identity cards on a voluntary basis, regardless of age. Because children are still in the long physical stage, their appearance will change with their growth, so unlike adults, the validity period of children's ID cards is short, only five years.

Only people over 16 years old must apply for identity cards according to the regulations. Therefore, only counting ID cards can get some personnel data information. In addition, some people have not obtained hukou, such as black hukou and no ID card. Although these people are few in number, they still exist.

Precautions:

Determine the county and district public security organs as responsible members of the local government census institutions, and strengthen the intervention of public security departments below the county and district level in the urban community census. Community police act as census instructors, organize and lead census takers into households, solve the problem that census takers cannot enter households, and fundamentally improve the quality and efficiency of census takers.

In densely populated communities, it is necessary to solve the problem of insufficient strength of film police as census instructors in time, and the county public security organs should come forward to coordinate, order the property management departments of residential quarters within their jurisdiction to actively cooperate with the census, hire property management personnel or property security personnel as temporary census instructors, lead enumerators to households, and complete the census tasks in their communities in a timely and effective manner.
