Use of the Urban Core Index to analyze residential mobility: the case of seniors in Canadian metropolitan regions

The present research intends to fill gaps identified in the current literature in the classification of the urban environment (i.e. city vs. suburbs), something that is important in urban and transportation planning, especially in the context of seniors. It does so first by proposing an urban/suburban classification that takes into account multiple census variables to provide a richer yet fine-grained and standardized classification of urban and suburban census tracts - the Urban Core. The Urban Core is then compared with the more common classification of the Inner City, that is based on age of housing. The proposed definition is then applied to examine if recent behavior of seniors has been consistent with the contention that they will increasingly move to the city - something that has been suggested in the media and grey literature. This is done by examining disaggregate data from four Canadian censuses on households moving to the Urban Core or suburbs, by age group. This is done initially graphically, and then logistic regressions are used to analyze how the effect of being a senior on moving to the Urban Core has evolved over the four censuses, while controlling for other socio-demographic variables. As such, using the proposed definition of the Urban Core, analysis suggests that seniors have been increasingly moving away from the Urban Core, behavior that is inconsistent with a hypothesis of a return to the city for seniors in the future.
