<P> A census is the procedure of systematically acquiring and recording information about the members of a given population . The term is used mostly in connection with national population and housing censuses ; other common censuses include agriculture , business , and traffic censuses . The United Nations defines the essential features of population and housing censuses as `` individual enumeration , universality within a defined territory , simultaneity and defined periodicity '' , and recommends that population censuses be taken at least every 10 years . United Nations recommendations also cover census topics to be collected , official definitions , classifications and other useful information to co-ordinate international practice . </P>
