While legal segregation has been banned for some time in many countries around the world, segregation still occurs through acts of social choices. The geography of those choices are evident in many urban neighborhoods where socio-economic classes, ethnic groups, and race often the main factors that segregate populations. Segregation, however, has been shown to transcend social and work space, where who we interact with online, offline, and where we work has a strong relationship to class, ethnic groups, and race.
Human Ecology and Segregation
Geographers have described human ecology, or our surrounding experiences and interactions, as shaping our sense of belonging in a place. Individuals who feel able to interact and express themselves more easily in a given place are more likely to feel a sense of belonging, leading them to make choices to be in that space. Over time, these selections can lead to segregation for people, as communities that become comfortable for some become less comfortable for others based on their sense of belonging.
Geography of Vacation Segregation
Interesting, while in daily lives, segregation is common, even on holiday a pattern of segregation is evident. A recent study using mobile phone data in Estonia showed that segregation increases when people choose to go on holiday destinations outside of their home city.
Positive and Negative Segregation
While segregation may appear as a negative, geographers do distinguish between more positive segregation, where populations of given groups concentrate in areas because they see these places as increasing their access to jobs and other social benefits, from negative segregation, where populations become excluded from socio-economic functions. In countries where ethnic or racial differences are less pronounced, segregation has been shown to occur based on other factors. In Korea, for instance, education has been show to be a strong reason for urban segregation in Seoul. While segregation show distinct patterns, today geographers differentiate forms of segregation as those that can have positive but also negative consequences.
