About this webinar

This seminar introduces the Residential Mobility Exposome File (ReMEF), a newly developed analytical resource linking long-term residential postal code histories to multi-domain environmental exposures — air pollution, built and green space, and thermal stress — over up to 25 years, within the Canadian Census Health and Environment Cohort (CanCHEC).

The presentation begins with an overview of the file's construction and a snapshot of the cohort profile, highlighting its potential to support natural experiments that leverage residential mobility to examine cumulative, multi-domain exposures and disparities over time, including their relationship to population-level health outcomes. Two ongoing applications of the ReMEF will be presented.

The first, an environmental justice application, explores differential ambient air pollution exposure trajectories among racialized and non-racialized populations in Canada. The second, a core environmental epidemiology application, examines multi-domain environmental exposures and non-accidental mortality, using residential mobility as a quasi-experimental design.

Together, these applications illustrate the value of the ReMEF as a foundation for future collaborative research in environmental health disparities, exposure trajectory analysis, and mortality outcomes research.
