Every ten years the Government undertakes a census, which collects a wide range of information on population, health, ethnicity, lone parents, households, and the economic status of residents.

The Census is the largest single statistical exercise undertaken by government and remains the most important source of information on the size and nature of the population. For many years, the Census has been relied upon to underpin national and local decision making. The Census is widely acknowledged as playing a fundamental and unique role in the provision of comprehensive and robust population statistics.

Background on the Census is available on the ONS Website: The Story of the Census
