The tenth and final city is "Suburbia Redefined." These communities are the suburban frontier of the GTA, forming a ring around the older mature suburban cores of Brampton, Mississauga, Richmond Hill, Milton, Markham, Pickering and others. These communities are home to about 16% of the GTA, or just under one million people, and have largely been built since 2001. While just 2% of the housing stock are apartments, single detached housing makes up just 63%. This means that the most recent wave of suburban development includes a lot of townhouse and semi-detached housing stock. This new generation of suburban development is also much more diverse than past suburban waves. Over half of residents are immigrants, and 72% of residents identify as racialized, far higher than any other "cities" in suburban GTA. These neighbourhoods also share the highest percentage of family households with the City of Hedged Communities (81%). While homeownership is (relatively) affordable compared to other parts of the GTA, these neighbourhods have the highest average monthly rent ($1690) and one of the higher levels of renter stress, with 47% of renters putting more than one-third of their income towards housing costs.
