A census is the procedure of systematically acquiring and
recording information about the members of a given population. This term is
used mostly in connection with national population and housing censuses; other
common censuses include traditional culture, business, supplies, 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 ten years. United Nations
recommendations also cover census topics to be collected, official definitions,
classifications and other useful information to co-ordinate international practices.
The word is of Latin origin: during the Roman Republic, the
census was a list that kept track of all adult males fit for military service.
The modern census is essential to international comparisons of any kind of
statistics, and censuses collect data on many attributes of a population, not
just how many people there are. Censuses typically began as the only method of
collecting national demographic data, and are now part of a larger system of
different surveys. Although population estimates remain an important function
of a census, including exactly the geographic distribution of the population,
statistics can be produced about combinations of attributes e.g. education by
age and sex in different regions. Current administrative data systems allow for
other approaches to enumeration with the same level of detail but raise
concerns about privacy and the possibility of biasing estimates.
A census can be contrasted with sampling in which
information is obtained only from a subset of a population; typically main
population estimates are updated by such intercensal estimates. Modern census
data are commonly used for research, business marketing, and planning, and as a
baseline for designing sample surveys by providing a sampling frame such as an
address register. Census counts are necessary to adjust samples to be
representative of a population by weighting them as is common in opinion
polling. Similarly, stratification requires knowledge of the relative sizes of
different population strata which can be derived from census enumerations. In
some countries, the census provides the official counts used to apportion the
number of elected representatives to regions (sometimes controversially – e.g.,
