A census<span> is the procedure of systematically acquiring and recording </span>information<span> about the members of a given </span>population. It is a regularly occurring and official count of a particular population.[1]<span> The term is used mostly in connection with </span>national population and housing censuses<span>; other common censuses include agriculture, business, and traffic censuses. The </span>United Nations<span> 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.</span>[2]<span>[3]</span>
