 The relational dimension of community has to do with the nature and quality of relationships in that community, and some communities may even have no discernible territorial demarcation, as in the case of a community of scholars working in a particular specialty, who have some kind of contact and quality of relationship, but may live and work in disparate locations, perhaps even throughout the world.Other communities may seem to be defined primarily according to territory, as in the case of neighbourhoods, but even in such cases, proximity or shared territory cannot by itself constitute a community; the relational dimension is also essential.Factor analysis of their urban neighbourhoods questionnaire yielded two distinct factors that Riger and Lavrakas (1981) characterized as "social bonding" and "physical rootedness", very similar to the two dimensions proposed by Gusfield.
