This research uses a longitudinal data set of commuting behavior to test the nature and strength of the association between residential change and employment location. Do households minimize commuting distances when they change residences and what are the differences for one-worker and two-worker households? The analysis utilizes descriptive measures of distance and time to work for pre- and post-residential relocations and develops estimates from a probability model of work-place attraction. We extend earlier research on commuting distances by using a multimodal rather than a monocentric city, by specifically considering the commuting responses of two-worker households and by formally estimating a model of the response to commuting distances. The findings indicate that both one- and two-worker households with greater separation between workplace and residence make decreases in distance and time. Overall, as other studies have shown, women commute shorter distances and are more likely to minimize commuting after a move than are men. The probability model fits the likelihood of decreasing distance with greater separation and provides a more exact specification of the connection between residence and workplace than previous analyses of this relationship.
