Three maps on this plate illustrate by census division, as of 1951, the percentage of population: under 20 years of age, 20-64 years of age, and over 64 years of age. Each of these maps is accompanied by a pie chart showing the percentage distribution by province and territory. The two remaining maps show urban and rural sex ratios using the number of males to 100 females by census division as of 1951. The rural sex ratio map is accompanied by a chart showing the ratio of males to 100 females by province and territory. As well, a chart accompanies the urban sex ratio map and shows the ratio of males to 100 females for chief urban centers. A set of age-sex pyramids that show the 1951 percentage distribution of males and females by quinquennial age groups for Canada, each province and the territories are also included.
