Thunder Bay's metropolitan area median total family income—below which half the households earned less and above which half the households earned more—was $68,476 in 2015, an increase of 8% since 2005.
That's according to a new batch of data out of the 2016 census which was released on Wednesday by Statistics Canada.
Household incomes in the five largest townships surrounding the city were significantly higher than the city proper's $66,163 in 2015.
They ranged from a median of just under $97,000 in both Oliver-Paipoonge and Shuniah at the top end to just over $87,000 in Neebing.
In Ontario, the median household income in 2015 was $74,287, an increase of less than 4% since 2005. That was the worst income growth rate among all provinces over that decade, reflecting a decline in manufacturing.
Elsewhere in northern Ontario, the median household income in 2015 was $61,814 in Sault Ste. Marie and $71,687 in Sudbury.
The Canadian median household income was $70,336.
The new data also shows Thunder Bay ranks in the top ten of Canada's census metropolitan areas for the proportion of its children who live in poorer households.
About 20 per cent of the area's children reside in low-income homes.
According to Statistics Canada, that is the eighth highest rate among the country's 35 largest urban centres.
Windsor tops the list with about 24 per cent, while Quebec City has the lowest rate, at just over 8 per cent.
The national average is 17 per cent.
