The 2011 rural-urban classification tool for locating and displaying the rural-urban classification for Output Areas.The 2011 rural-urban classification (RUC2011) allows for a consistent rural/urban view of datasets. A suite of classifications has been produced for use at a variety of geographic levels. RUC2011 is a revised version of the classification produced after the 2001 Census. It was created by the Department of Town and Regional Planning at the University of Sheffield on behalf of a government working group.RUC2011 of OAs, the most detailed classification, is the base from which all other classifications are produced.OAs are treated as ‘urban’ if they were allocated to a 2011 built-up area with a population of 10,000 people or more, while all remaining OAs are classed as ‘rural’. The urban and rural domains are then subdivided into six broad settlement types. The classification also categorises OAs based on context, that is whether the wider surrounding area of a given OA is sparsely populated or less sparsely populated. RUC2011 of OAs contains 10 classes - for more details see the user guide
