The official unemployment statistic is entirely unreliable because people drop out of the labour force if good jobs with a level of convenience are not available. In the deep recession of the 1990's the City of Toronto labour force lost 11.15% of workers to this in four years. That is there was an additional 11.15% hidden unemployed on top of the official unemployment, at least, in just four years.
The 11.15% figure comes from a custom run on Statistics Canada labour force survey data that the City of Toronto keeps. At the peak in March 1990 the labour force was 69.6% of adults while four years latter in Feb. 1994 it was 61.84%. The arithmetic is the 11.15%. The figure clearly shows how volatile the labour force is - some 11.15% of the population found alternate means of support such that they could do other things.
The official unemployment in Canada currently is 8% or so. This is entirely unreliable as labour markets are so soft everywhere and there will be "hidden unemployment".
I've post this idea before but the City of Toronto data is nice and graphic.
