The facts about the urban exodus.

"Urban deconcentration is the most dominant and consistent feature of population movement in Britain nowadays.... The scale of urban out-migration varies over time, some types of people and places are more fully represented in the urban exodus than others, and the net figures hide the fact that quite sizeable numbers of people move in the opposite direction.... The research was based largely in 1991 Population Census data on people who changed address within Great Britain during the year preceding Census night, focusing mainly on migration between local authority districts grouped according to their degree of 'urbanness' and their distance from the main metropolitan centres."
