This dataset includes data from the 2011 Census released by the Office for National Statistics (ONS)

Notes and Definitions

1. The main population base for outputs from the 2011 Census is the usual resident population as at census day (27 March 2011).

Although the population base for enumeration included non-UK short-term residents, these are not included in the main outputs from the 2011 Census, but are analysed separately. All outputs, unless specified, are produced using only usual residents of the UK.

2. For 2011 Census purposes, a usual resident of the UK is anyone who, on census day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

3. Further information about the census estimates, including details about the methodology and other definitions used, how other population sub-groups are counted, Output Area maintenance and other geographic information, are available on the ONS website at


ONS as the executive arm of the UK Statistics Authority has a legal obligation not to reveal information collected in confidence in the census about individual people and households. The confidentiality of all census results, including the counts in this release, is protected by a combination of a variety of disclosure protection measures.

2011 Rural-Urban Classification

The outputs are based on a rural-urban classification of output areas.

Output areas are treated as urban if they were allocated to a 2011 built-up area with a population of 10,000 or more people. The domains are sub-divided into broad morphological types based on the predominant settlement component.

Long term health problem or disabilityJan 2011

Long-term health problem or disability A long-term health problem or disability that limits a person's day-to-day activities, and has lasted, or is expected to last, at least 12 months.

This includes problems that are related to old age. People were asked to assess whether their daily activities were limited a lot or a little by such a health problem, or whether their daily activities were not limited at all.

EthnicityJan 2011

Ethnic group classifies people according to their own perceived ethnic group and cultural background.

ReligionJan 2011

This is a person's current religion, or if the person does not have a religion, 'no religion'. No determination is made about whether a person was a practicing member of a religion. Unlike other census questions where missing answers are imputed, this question was voluntary, and where no answer was provided the response is categorised as 'not stated'.

MigrationJan 2011

People who moved in the year preceding the census. Net migration within the UK subtracts the number of people who have moved into the area, from elsewhere within the UK, from the number of people who have moved out of the area, to elsewhere within the UK. It does not include people who have moved to or from outside the UK.

People who were resident in the area one year ago, but have moved to outside the UK are not counted.

Provision of unpaid careJan 2011

A person is a provider of unpaid care if they look after or give help or support to family members, friends, neighbours or others because of long-term physical or mental ill health or disability, or problems related to old age. This does not include any activities as part of paid employment. No distinction is made about whether any care that a person provides is within their own household or outside of the household, so no explicit link can be made about whether the care provided is for a person within the household who has poor general health or a long-term health problem or disability.
