Social distance describes the distance between different groups in society and is opposed to locational distance. The notion includes differences such as social class, race/ethnicity, gender or sexuality, but also the fact that the different groups mix less than members of the same group. The term is often applied in cities, but its use is not limited to that.
In the sociological literature, social distance is conceptualized in several different ways.
It is possible to view these different conceptions as "dimensions" of social distance, that do not necessarily overlap. The members of two groups might interact with each other quite frequently, but this does not always mean that they will feel "close" to each other or that normatively they will consider each other as the members of the same group. In other words, interactive, normative and affective dimensions of social distance might not be linearly associated.
Social distance was also used in a different meaning by anthropologist and cross-cultural researcher, Edward T. Hall, to describe the psychological distance which an animal can stand to be away from its group before beginning to feel anxious. This phenomenon can be seen in human babies and toddlers who can only walk or crawl so far from their parents or guardians before becoming anxious and quickly returning to the safe space. The babies’ social distance is quite small.
Hall also notes that this concept of social distance has been extended by technological advances such as the telephone, walkie talkie, and television, among others. Hall’s analysis of social distance came before the development of the internet, which has expanded social distance exponentially. Social distance is now even expanding beyond our planet as we send people into outer space on space missions and even personal trips to space.
