This book emerges from the work of Soillse's Islands Gaelic Research Project (IGRP) conducted between 2015 and 2017. Soillse was a research collaboration, established between founding members – the University of the Highlands and Islands, the University of Aberdeen, the University of Edinburgh and the University of Glasgow – to provide a much enhanced research capacity to inform public policy towards the maintenance and revitalisation of Gaelic language and culture. This publication provides contemporary data and analysis of the societal and spatial extent of Gaelic speakers and Gaelic speaking in the remaining vernacular communities in Scotland. The survey modules examined: census demolinguistics; preschoolers' language practice; teenager data; three indicative communities and speaker typologies, providing qualitative and quantitative information on community, family, school and individual language acquisition and practice.
