United Kingdom Census 2011

United Kingdom Census 2011

The most recent census of the United Kingdom, known as the 2011 census, took place on 27 March 2011, a decade after the previous census. It was conducted on the same day in England and Wales, Scotland and Northern Ireland to ensure coherence and consistency. The Office for National Statistics (ONS) is responsible for the census in England and Wales; the General Register Office for Scotland (GROS) is responsible for the census in Scotland and the Northern Ireland Statistics and Research Agency (NISRA) is responsible for the census in Northern Ireland.

The Office for National Statistics (ONS) is the executive office of the UK Statistics Authority, a non-ministerial department formed in 2008 and which reports directly to Parliament. ONS is the UK Government's single largest statistical producer of independent statistics on the UK's economy and society, used to assist the planning and allocation of resources, policy-making and decision-making. ONS designs, manages and runs the census in England and Wales. In its capacity as the national statistics office for the United Kingdom, ONS also compiles and releases census tables for the United Kingdom when the data from England and Wales, Scotland and Northern Ireland are complete.

First results from the 2011 Census, in the form of age and sex, and occupied households estimates for England and Wales and Northern Ireland were released on 16 July 2012. The first results for Scotland were released on 17 December 2012. The first United Kingdom wide results were also published on 17 December 2012. Subsequent releases were made and are planned throughout 2013 and more specialist themed data will be published from 2013 onwards.
