I first met Monika Jaroszonek in 2017, right before she started RATIO.CITY. Since then she has developed some pretty incredible tools for the city building space.
Yesterday the company published this interactive visualization looking at development potential across the City of Toronto. The mapping looks for the following:
Land that has a Mixed Use, Apartment or Regeneration designation in the City of Toronto’s Official Plan
Land that is located within a Provincially designated Urban Growth Centre
Land that is located within 500m of a Major Transit Station
The tool then ranks each development site – AAA, AA, A – according to how many of the above criteria it meets.
It also flags land that it refers to as “Missed Opportunity.” These are lands located within 500m of a Major Transit Station, but that are designated as Neighbourhoods (considered stable) or Employment (whole other discussion).
Based on this filter, about 5.6% of the City’s land is a “Missed Opportunity” and about 1.2% is AAA.
When you look at the visualization, that is one of the first things you will probably notice; a lot of our transit infrastructure is currently underutilized as a result of land use policies.

The United Nations recently released its 2015 version of World Population Prospects. It looks as if they put out and revise this report every 5 years.
The Economist then took some of their data and assembled it into the following charts:

One interesting takeaway is that population growth continues to centralize in the region’s core. Since 2010, 60% of the region’s population growth has taken place in the five boroughs of New York City, and in particular it has occurred in neighborhoods with strong rail transit.
There has also been a slowing in terms of the number of residents leaving New York City. Historically, people moved to the city in their 20′s and left in their 30′s. That trend is slowing.
I suspect this has to do with a combination of factors, including the shift toward a city-centered knowledge economy; the desire for walkability and urban amenities; the phenomenon of people getting married later in life (if at all); and so on.
The people who do leave the city are also more likely to leave for other parts of the U.S. than other parts of the region. This has led to a decline in the number of prime age (25-54 years old) workers in the suburbs.
Check out the Metro Region Explorer, here. There’s a lot of good stuff in there.
It’s obviously extremely difficult to predict what will happen in the world by 2100, but to the extent that forecasting is possible, the world’s population is expected to reach somewhere around 11.2 billion people. Today it’s 7.3 billion.
The bulk of this growth is expected to happen first in Africa, and then in Asia. By 2100, Africa’s share of the global population is expected to grow to 39% and Asia’s share is expected to decline to 44%.
If you’ve been following population trends, most of this shouldn’t come as a surprise to you. The meaningful population growth happening in the world today is happening in the developing world.
That’s why architects, such as Rem Koolhaas, have been studying cities like Lagos (Nigeria) since the late 1990s and early 2000s. Below is a photo from a book/research project that I love called Mutations (2000). I pulled it from my bookshelf this morning.

It’s interesting to think about what all of this will mean for the global economy and for global governance.
The United States is about to be alone when it comes to advanced economies with a globally competitive population. Europe is shrinking, which leads me to believe that a strong EU is likely important. And we now have lots of megalopolises with big populations, but with very low income levels.
Nigeria is the largest economy in Africa, but per capita income is somewhere around $3,000.
