To meet the needs of the Ministère des Affaires municipales et de l’Habitation, the Institut de la statistique du Québec designed and produces a composite index in order to measure, on a regular basis, the economic vitality level of municipalities, Aboriginal communities, unorganized territories, and regional county municipalities (RCMs).
This economic vitality index consists of the geometric mean of normalized variables for three indicators: the rate of workers, the median total income of individuals, and the average annual population growth rate over five years. Each of these indicators represents an essential dimension of vitality, respectively the labour market, living standards, and demographic dynamics.
The economic vitality index was produced every year from 2002 to 2014. Since then, it is updated every two years by the Institut de la statistique du Québec.
