The population census is not just a government affair, nor is it the task of an employee who performs his duty and ends the matter; it is a national work that benefits the citizen before any other party, and for this reason, every "correct information" provided by the citizen today can be part of a better decision tomorrow, whether it is about a school needed in an area, a health center, a road, a transportation network, housing, or infrastructure and public services.
The importance of the census lies in providing a comprehensive, accurate, and updated database on the population, housing, and their geographical and age distribution. A state that does not know the number of its "population, their distribution, and characteristics" may not be able to plan realistically. Planning for education, health, transportation, housing, and infrastructure certainly requires accurate information to know where the need is increasing and where the nature of the population and their needs are changing.
