In Canada today no single ethnocultural group makes up a majority of the population. Increases in the number of immigrants, especially people from Third World nations, continue to accelerate Canada's ethnocultural heterogeneity. A new descriptive term "visible minority," is now used to describe persons who are non-white, and distinct from the British, French, Aboriginal Peoples, and other ethnics who formerly comprised the majority in Canada. In the Canadian context, "ethnics" have usually been either immigrants or the descendents of immigrants whose origins were countries other than the British Isles or France. As part of the 1981 Census, Canadians were asked to identify the ethnic or cultural group they or their ancestors belonged to before coming to Canada using the 1981 demographic and socioeconomic profiles of the following groups of Canadian residents: (1) Black and Caribbean; (2) Chinese; (3) Czech and Slovak; (4) Dutch; (5) Filipino; (6) German; (7) Greek; (8) Italian; (9) Japanese; (10) Jewish; (11) Polish; (12) Portuguese; (13) Scandinavian; (14) South Asian (Indo-Pakistani); (15) South East Asian (Indo-Chinese); (16) Ukrainian; and (17) Yugoslav. Demographic data for each group are presented separately and percentages are given comparing the groups to the entire Canadian population in terms of location, age structure, mother tongue, occupation, labor force participation, income and education.
