The Index of Economic Disparity: Measuring trends in economic disparity across Canadian Census Subdivisions and rural and urban communities

Territorial inequalities have long been a subject of study and concern in Canada. In the face of large structural changes such as industrial shifts and the decarbonization of our economies, there is an urgency to understand such inequalities and design effective policy interventions for those places facing persistent economic decline. This paper shares a novel composite index that measures economic disparity across Canadian Census Subdivisions (CSDs) using Census data from 2001 through 2016 and the 2011 National Household Survey. Named the “Index of Economic Disparity,” it is comprised of an equally weighted average of four sub-indices that assign percentile rankings for all CSDs based on whether they experience persistent and substantial decline in key economic areas: population, labour force outcomes, working-age share of population, and industrial diversity. The variation of outcomes across geographies—urban and rural—highlights the importance of place-based policies.
