Leger Marketing’s new poll is the largest national energy-environment-economy survey done to date and uses accepted techniques for keeping error margins well below five per cent. The work was done in mid-2010. The random sample of 3,032 Canadians was 48-per-cent male and 52-per-cent female. Of the total, 19 per cent were 18 to 34 years old, 28 per cent 35-39, 33 per cent 50-64, and 20 per cent 65 or older. Geographically, 63 per cent of poll participants lived in the central Canada region of Ontario Quebec, seven per cent in the Atlantic provinces and 30 per cent in the West. Graduates of post-secondary education programs were 37 per cent of the sample. On the income scale, 28 per cent had annual earnings below $50,000, 27 per cent were in the $50,000-$90,000 bracket, and 26 per cent had $90,000 or more.
