This report draws on data from the 2021 Census of Population, alongside previous census cycles to identify changes over time in the linguistic profile of Indigenous language speakers living in a Census Metropolitan Area (CMA) or Census Agglomeration (CA). In addition, supplementary statistics using the 2022 Indigenous Peoples Survey, which asks questions on the importance of Indigenous languages, were also included. Finally, 12 CMAs and CAs were selected for focused analysis, in order to highlight the specific linguistic communities in these areas.
