Cheryll Case, Ryerson Grad, puts some numbers to the Yellowbelt

"The report comes from recent urban planning grad Cheryll Case, along with Tetyana Bailey. When they matched the city’s zoning boundaries with recent Census information, the researchers found that 30 neighbourhoods actually declined in population and another 65 were essentially frozen, gaining less than one person per kilometre despite the city’s 7.6 per cent population growth between 2001 and 2016."
