Census

A census is the process of systematically obtaining and recording data about the members of a specified population. This term is used mostly in linking with national population and housing censuses; other common censuses include traditional ethos, business, supplies, agricultural, and traffic censuses. It is also a collection of information from all elements in the population or a ‘complete enumeration’ of the people. We practice a census when we want accurate information for many sectors of the population. Such a survey typically requires a very large sample size and often a census offers the best solution.

Advantages of Census:
The advantages of a census are that:

  • Data for small areas may be obtainable, assuming satisfactory answer rates are achieved.
  • Data for sub-populations may be obtainable, assuming satisfactory comeback rates are achieved.
  • (Because of the above reasons) detailed cross-arrangements may be thinkable.
  • The estimates are not subject to sampling fault.
