The Census took place on 27 March 2011 and provides statistics on every resident in the UK regarding their home and work. The information is entirely confidential so that no individual can be identified.
The information collected is used by the county, district, and borough councils, health authorities and other organisations to plan for the provision of public services.
The ONS has released estimates showing the population of England and Wales has increased by more than 3.7 million since 2001.
Latest information includes:
- ward data
- population density
- average ages
- ratios of elderly people who require support.
Further release dates are provided in a timetable available in the document below.
Output Areas were created after the 2001 Census and are the lowest geographical unit at which census estimates are provided. They are designed to have similar population sizes and, as far as possible, contain similar types of households. Output Areas are amalgamated to form Lower Super Output Areas and Middle Super Output Areas.
Where possible the ONS has tried to maintain the existing boundaries following the 2011 Census. However, some changes have taken place since 2001, mainly due to population changes where new development has taken place. The 'Boundary geography briefing note' document below explains how these changes affect West Sussex.
