A census is a way of getting information about every member of a population. It is usually used for a population of people, but can be used to mean a population of animals. Both the United States and United Kingdom have a census every 10 years, or decade. But in Australia, Canada, Japan[1] and New Zealand they have it every 5 years.

A census produces a large database and sometimes new information technology, such as the use of punched cards for data, has been invented to handle it.
