We proposed (Giguère, 2013), for francophone communities outside Québec (FACMS), a jurisdictional pattern that illustrates supply and demand for health services in French as a function of a critical mass of Francophones that reflects the linguistic vitality of these communities. We corroborate this pattern through statistical procedures of which one identifies a strong association between supply/demand (a ratio) and factors that represent linguistic coherence for the two official languages communities. This result is coherent with the linguistic vitality framework proposed earlier (Giguère, 2013) and the field work of Forgues, Bahi, and Michaud (2011) and the language behaviour and cultural autonomy models of Deveau, Landry and Allard (2009), Landry, Allard and Deveau (2007, 2008) and Landry (2012). We carry out simulations for the development of health services in French for FACMS in the context of a national framework which is coherent with these empirical and theoretical foundations. This modeling suggests two distinctive but complementary strategic approaches to stimulate the development of health services in French.
