Undersøgelser af Barrett (1976) i Toronto og af Lyon og Wood (1971) i London viste, at uanset deres begrundelse for at flytte var eftersøgningen efter ny bolig hverken objektiv eller grundig; de fleste husstande gennemgik kun et par steder i et kort tidsrum.
Studies by Barrett (1976) in Toronto and by Lyon and Wood (1971) in London found that irrespective of their reasons for residential moves, searches were neither objective nor thorough; most households analysed only a few locations over a short period of time.
