Something I find interesting looking into the polls is a seemingly huge over-correction for age in the polls.
For example, a new Leger poll from September 23 to 25 has the BCC at 45 and the NDP at 43 among decideds. However, this is despite the fact that in the unweighted data, the NDP is actually at 47% and the BCC at 40%, a 7 point lead for the NDP.
You can see that the weights for age are dramatically different, adding a lot of weight for younger voters and less weight for older voters. The adjustment goes from 44% of respondents being 55+ weighting it to 42%, 35% for 35-54 to 32%, and a big boost for 18-34 from 21% to 26%.
This would be fine if voter turnout was even across the age groups, but its not. In the 2020 election, 54% of voters were 55+, 29% in middle age and 17% for 18-34. They seem like they would have been better to have not weighted it at all, if they wanted to reflect voter turnout.
Anyways, just seems like a 9 point swing in voter intention based on weighting the demographics seems extreme. Would seem like polls are underrepresenting old people's polling, which some polls show are stronger with the NDP but others with the Conservatives.
