The major applications of copper are electrical wire (60%), roofing and plumbing (20%), and industrial machinery (15%). Copper is used mostly as a pure metal, but when greater hardness is required, it is put into such alloys as brass and bronze (5% of total use).
Population Distribution, 2006. According to the 2006 census, the population of Canada was 31 612 897 on May 16, 2006. This map shows the population distribution, based on the population density and the population counts of census dissemination blocks. A dissemination block is generally an area the size of a city block bounded by intersecting streets. There are 478 831 blocks across Canada.
There were 5,780,900 Canadians 65 and older on July 1. That compares to an under-15 population of 5,749,400. In percentage terms, 16.1 per cent of Canadians were in the 65-and-over group in July, with under-15s accounting for just 16 per cent of the population.ut by international standards, Canada's population of 65-and-overs is still relatively small, and lower than any other G7 nation. In Japan, for example, 26 per cent of the population is over age 64. The bulge of aging baby boomers isn't increasing evenly across Canada, however.
