In industrialized countries, there are often residential squats and also political squatting movements, which can be anarchist, autonomist or socialist in nature, for example in the self-managed social centres of Italy or squats in the United States. Oppositional movements from the 1960s and 1970s created freespaces in Denmark or squatting village in the Netherlands, and in England and Wales, there were estimated to be 50,000 squatters in the late 1970s. Each local situation determines the context: in Athens, Greece, there are refugee squats; Germany has social centres; in Spain there are many squats.
