The Martin Prosperity Institute here in Toronto just released a new research study called Segregated City: The Geography of Economic Segregation in America’s Metros.
The report looks at the physical sorting and separation of advantaged and disadvantaged groups within cities. And it did so across 70,000+ Census tracts in the US and in terms of 3 different dimensions: income, education, and occupation.
Here are the most segregated “large metros” in the US:

And here are some of their broader findings – taken verbatim from page 9 of the study (click here for the full report):
Economic segregation is positively associated with population size and density. It is also positively correlated to two other sets of factors that follow from metro size and density: how people commute to work and the breakdown of liberal versus conservative voters.
Economic segregation tends to be more intensive in high-tech, knowledge-based metros. It is positively correlated with high-tech industry, the creative class share of the workforce, and the share of college grads. In addition, it is associated with two key indicators of diversity, the share of the population that is gay or foreign-born, which tend to coincide with larger, denser and more knowledge-based metros.
Economic segregation is connected to the overall affluence of metros, with positive correlations to average metro wages, income, and economic output per capita.
Race factors in as well. Economic segregation is positively associated with the share of population that is black, Latino, or Asian, and negatively associated with the share that is white.
Economic segregation is associated with income inequality and even more so than with wage inequality. Its effects appear to compound those of economic inequality and may well be more socially and economically deleterious than inequality alone.
The research team also looked at how Canada’s 3 largest metros – Toronto, Montreal, and Vancouver – compare to those in the US in terms of segregation.
The finding was that Canadian cities are overall less segregated than US cities, but that it should still be considered an area of concern. The most segregated of Canada’s 3 largest metros was found to be Montreal.

My view is that our economy is going through a profound shift right now. We’re transitioning from the industrial age to the information age. And in its wake, we’re seeing a number of disruptions, one of which appears to be rising inequality and segregation.
That’s not to say that I think this transition is a bad thing (I don’t think it is), but I do think we should be carefully considering and designing our future.
I’ve spoken about global cities, such as New York and London, many times before on Architect This City. I’ve also talked about the rise of consumer cities. That is, cities with a high “urban amenity premium”, which could be great outdoor amenities or great restaurants, theatre and so on. These are places of consumption.
Sometimes global cities and consumer cities are one and the same. But there are also cities–such as Vancouver–where I view the urban amenity premium as outweighing their status as a global city. Vancouver, quite simply, is an awesome place to live and enjoy life. I almost went to UBC for grad school because of Whistler Blackcomb and the city itself.
Today, I’d like to introduce another type of city into the discussion mix: the necessary city. I heard about it here and, although it seems somewhat intuitive, I think it’s an important reminder that, even though a city may not be an alpha global city, it may be fulfilling a specific function for a particular industry or aspect of the global economy. It may still be a necessary city for your corporate headquarters.
For example, Houston is the city for energy companies. If that’s your business, you likely need a presence there. For fashion and luxury, it’s Paris. And if you’re in the auto industry:
The major global equipment manufacturers are widely dispersed, but when you look at leading global parts suppliers, they virtually all have their North American headquarters in Detroit – including the German, Japanese and Korean ones. Among them are companies like Robert Bosch, Denso, Yazaki and Hyundai Mobis. If you’re in the auto industry in America, you have to deal with Detroit. Unsurprisingly, Detroit boasts several nonstop flights to key Asian destinations.
In essence, we’re talking about cities making themselves necessary by becoming niche experts. And what I think is interesting about this concept is that it’s likely much more attainable for a lot of cities. Most cities will never become New York. And most cities will never be able to transform themselves into the next Silicon Valley.
But maybe those are the wrong economic development goals. It’s not about becoming the next, whatever; it’s about finding and owning a particular niche and making yourself absolutely necessary to the global economy.
