< Back to Work

The 2021 census switched to NOC 2021, which moved middle managers out of the management category and into the category of the field they manage. Category 0 is far smaller in 2021, and the other categories grow, for that reason alone.

Percentages cover the labour force aged 15 and over who worked since January of the year before the census. People who have not worked in that time have no class of worker, occupation or industry and are left out.

These estimates come from the long-form questionnaire, which was distributed to a 25% sample of private households. They are subject to sampling variability and may differ from a full enumeration. Read more

To protect confidentiality, Statistics Canada randomly rounds census counts up or down to a multiple of 5 or 10. Totals are rounded independently of their parts, so sub-totals may not match the total and percentages may not add up to 100%. Read more
