We investigate in municipality with houses where we always live in regardless of giving report of resident certificate.

Q
Even if national census does not investigate all the members, is sample investigation not all right?

Even if result of national census is based for population prediction in "legal population" including delimitation standard of single-seat constituencies of member of the House of Representatives and calculation standard of decision, tax allocated to local governments of the member of the Local Assembly fixed number and the future, it is used. Therefore, we grasp accurate population by complete survey, and it is necessary to make reliable statistics.

A

It is necessary to get the actual situation of the residence of people and household definitely to push forward local administration appropriately.

However, we do not report immediately even if we move house and one lives with leaving resident registration for the parents' house and goes to university, and entrance shiteitarinado, Basic Resident Register and the actual situation may be different apart from family in taking up job leaving his family behind and hospitalization, facility.
For example, it is necessary people and commuting that actually live in the area to grasp number of people going to school exactly when it assumes measures at the time of disaster. It may be said that data of national census are suitable than Basic Resident Register as statistics becoming standard of administrative administration in line with the life actual situation from such a point of view.

We list only of man and woman, 4 information of Address and limited information called full name and relation of family nurturer in Basic Resident Register on full name, the natal date and, for example, cannot get statistics information about various actual situation of population grasped in national census including difference of the number of the employees according to industry, occupation, daytime population and night population from Basic Resident Register.
In addition, as for "my number", the use, offer except range established in law is prohibited. As the use is accepted only for administrative procedure of social security, tax, anti-disaster measures for the time being, we cannot use in national census.

National census is complete survey to perform targeting at all people living in Japan. When person who is subjects of survey is missing alone, is right; do not collect the statistics.
