Mental map variability: A migration modeling problem

Mental map variability is important when viewed in a migration prediction context. Models that link aggregate mental maps of residential desirability to migration have limited predictive value because mental maps vary among socioeconomic groups and migrants often have very different socioeconomic characteristics than the general population within a source region. Residential desirability also varies with both the distance to and the intensity of awareness for alternative destinations. Utility can be increased by disaggregating the mental maps of potential migrants on the basis of accessibility to potential destinations, socioeconomic status, and awareness levels for alternative locations.The author wishes to acknowledge the thoughtful comments of Professor Richard Jones on an early draft of this paper. The assistance of Ms. Gail Leithauser who tabulated much of the data also proved most helpful.
