Both the growth and the crisis stages of urban society in Madrid have produced dramatic transformations to its social structure. As a consequence, the intensity of residential segregation within this territory had a remarkable increase between 2001 and 2011.

As a result, the traditional peripheries in which these categories used to live have become the place where precariousness is concentrated.
