Close to 70% of housing in Denmark is within a cooperative housing scheme. Anyone buying a house or an apartment pays for the right to use that unit, and their payment covers a share of the wealth of the cooperative itself. The tax structure is designed to keep these units affordable, protecting the residents financially and from homelessness. As people across the socio-economic spectrum can be sharing a co-op, connections can be built between retired workers, young students, doctors, policemen, artists, and so on. Co-operative housing can be found everywhere in the city.
