As I mentioned, there are many factors that can have an influence on the vitality of those languages. All specialists mentioned that speaking a language at home is certainly a critical domain, but as we know, it's not only speaking a language at home, but also it involves social networks. It involves visibility, status, and prestige.
When a language is spoken in the public domains, in the administration for instance—when you look at Inuktitut you know that those using Inuktitut at work do so mostly in government agencies for the administration, for the delivery of services. This certainly has an impact on the future and vitality of these languages; so not only being spoken at home but being visible in the public domain will certainly have an impact on the status and use of these languages.
