Agreement among economists on what constitutes Canada's middle class. It varies based on whether you look at family or individual income, provincial or national data, before or after tax. Here we look at median and total family income to get a sense of the range.

$69,860

The median total income for all Canadian families. That's the dead centre of all family total income earned in Canada in 2010, meaning half earned more than $69,860 and half earned less. (Source)

$60,000 - $85,000

The family income range that puts you in the middle quintile (one-fifth) of Canadian families (total income, 2009). (Source)

57

Percentage of all income earned in Canada that went to the middle 60 per cent of Canadian families in 1972. By 2006, that number had dropped to 53 per cent. That's what some people mean when they talk about the shrinking middle class: they're getting a smaller piece of the income pie. (Source)

20th century

The conceptualization of 'the new middle class'. In his day, sociologist C. Wright Mills distinguished it as educated, well-paid workers who were often in positions of authority. We know it better as the distinction between 'white collar' and 'blue collar' jobs. In short, the middle class is a social construct that keeps changing over time. (Source)

The Canadian Centre for Policy Alternative's Trish Hennessy has long been a fan of Harper Magazine's one-page list of eye-popping statistics, Harper's Index. Instead of wishing for a Canadian version to magically appear, she's created her own index -- a monthly listing of numbers about Canada and its place in the world. Hennessy's Index -- A number is never just a number -- comes out on the first of each month in rabble.ca.
