This is the report of a Commonwealth seminar held in Mauritius in January 1975. At the seminar representatives from twelve island member states met to examine the dimensions of pluralism and its implications for development, with particular reference to island communities. Participants at the seminar, which was organised under the Commonwealth Youth Programme, included a wide range of personnel associated with youth work as well as young people themselves, and an attempt was made to explore ways in which young people might contribute towards integrating and furthering the development of their societies. This report will be of value to youth and community development workers throughout the Commonwealth and especially those in plural societies.
