You said 50% of people earn less than 29,700. Ie 50% earn more. That is exactly the definition of median, the amount where 50% earn less, 50% more.
I didn't say anything about 50%. You did.

You're haven't given a fig for low income cutoff - surely not 29700, ie 50% Seems to me if you use the term middle, low and high, you'd assign 1/3 of the earners to each category.
I did give a figure for low income cut-off:
Winnipegger Winnipegger:
Statistics Canada:
Low income cut-offs before and after tax by community and family size, 2011 constant dollars$1:
Community size: Population 500,000 and over - Low income cut-offs before tax: $23,298
That last quote is pulled from a table.
This makes middle class, for cities with population over half a million, to be: $23,298 to $80,400. That is total family income, so for married couples that's the total of both incomes.
Of course the $80,400 figure comes from the CBC table. That story was published in September. The Statistics Canada web page from December said $84,100. Again, I'm using the low income cut-off as the lower bound for "middle class", and the cut-off for the upper 10% as the upper bound. "Median" is just half way between whatever bounds you choose. Considering the top 0.01% of income earners have such ridiculously high income, any calculation of "median" would be badly skewed. "Mean" means average; that would be calculated by adding up declared income for everyone who submitted an income tax return, and dividing the sum by the number of returns. Any plot of income will be a bell curve. The vast majority will be in the middle. I think using the low income cut-off as the lower bound is reasonable. What would you use as the upper bound? Top 10%, 5%, 1%?
