You could say social and geographic mobility. As I said, it takes a little effort to get past the academic language. Socio spatial mobility is the ability of people to move into a higher social and / or economic class by getting a better job, or learning a new way of life, in a new part of the country or indeed new country. People who live in sink council estates generally also have a poor education, poor quality neighbours, poor housing and poor job opportunities. They are either unaware of opportunities elsewhere or are unequipped to take them. These circumstances tend to run in families through the generations but are not, by and large, genetically determined.
