This Alberta Official Statistic describes the proportions of Aboriginal Identity population by Mother Tongue (English, French, Aboriginal Languages and Other Languages) for Canada, Provinces and Territories based on the 2011 National Household Survey. Between May and August 2011, Statistics Canada conducted the National Household Survey (NHS) for the first time. This voluntary, self-administered survey was introduced as a replacement for the long census questionnaire, also known as Census Form 2B. The NHS is designed to collect social and economic data about the Canadian population.
