Census registration is individual and direct. From the perspective of investigation methods, in principle, personal data should be directly reported by the parties. However, in the actual survey, not everyone can self-declare, for example, infants or young children or people who are on a business trip, travel, or are not at home at the time cannot self-declare, and each household should designate a person who is familiar with the situation to truthfully declare on behalf of the family.

Due to births, deaths, migrations, etc., the population is subject to change at any time, so the census must be based on a specific point in time, and the census must be conducted simultaneously across the country.
