Explanation: Census is the systematic collection of information about members of a particilar population. The national population census is the process of knowing the number of people in a country. It is very important to know the total population as it affects almost all the decisions that would be made in the country.
In the US, a system called apportionment is used to determine representation in congress whereby number of residents in each state determines how many seats they have in the house of representatives.
The census also ensures each community, constituency and state get their fair share of federal funding for schools, hospitals, roads and other infrastructure.
Through total number and demography, census is instrumental in inflencing tax policies. It helps in management and distribution of resources for maximum benefit of the country as a whole.
