The Mouvement des caisses populaires acadiennes will celebrate its 75th anniversary in 2011. During its history, the organization has evolved to encompass a current membership of close to 200,000, accumulated assets worth 2.5 billion dollars and an organizational structure set up to support the Caisses’ services. Forever changing, the concept of vitality helps communities in minority situations to achieve a greater understanding of what they need to survive and thrive in distinct and active ways. Analyzing an organization’s contribution to vitality is a seldom-used research approach. The analysis results emphasize that the Mouvement contributes to the vitality of New Brunswick’s Francophone and Acadian communities by its results, assets, cooperative values and socio-economic implication.
