The article describes residential mobility in México City and finds evidence of a collocation process between jobs and housing. The methodology employed is based on a series of statistical analyses including a log-log regression of residential mobility flows between municipalities, as well as a binomial logistic model that predicts the probability of changing residence with given changes of job location. We conclude that together with the socioeconomic characteristics of residents that move, there is a clear influence of the place of work on the choice of housing location. We conclude that residential mobility can be seen as a social equilibrium mechanism that acts as a response to changes in urban structure.
