Organic solidarity, according to Durkheim, was a form of society based on interdependence through differences, such as that resulting from the division of labour or urbanisation. Hillier addressed the spatial dimension of this concept by stating that organic solidarity requires an integrated and dense space, where co-presence or proximity is realised. See: Mechanical solidarity.
