Segregation can also be caused by social factors that become evident as they happen, but are not necessarily government sanctioned. This could be things like informal ghettos, or simply rich neighborhoods. In terms of land capital, over time in a given area, humans will settle down and buy or take land. Some privileged people will acquire better land (that is, more arable, proximate to potential capital, more pleasing views). Demand for these nicer habitats drives up prices, and areas deemed “better” based solely on geography become inherently exclusionary in their population makeup.
