Sidewalk Labs is currently building out a platform called Replica that will support them in their development plans here in Toronto. Replica is:
“a user-friendly modeling tool that uses anonymized mobile location data to give planning agencies a comprehensive portrait of how, when, and why people travel in urban areas.”
Here is a preview of the Replica dashboard showing a section of Main Street in Kansas City. I hope the animated GIF shows up for you.

The platform uses a combination of mobile location data (~5% of the population) and on-the-ground checks, typical stuff like manual traffic counts and transit boardings.
The goal is to understand in real-time who is using a street, as well as how (driving? cycling?) and why (going to work?).
Their introductory blog post obviously stresses the importance of personal privacy, but I am curious how they determine where people are going.
I suppose if they pair journeys with destinations (and the durations at those destinations) they can make reasonable assumptions around the why.
I think the benefits to all of this are clear. But does any or all of this worry you from a privacy standpoint?
The Guardian recently published this reminder that the real population growth in the world today is happening in Asia and Africa. The article is called, “The 100 million city: is 21st century urbanisation out of control?” Much of the data is from this 2016 paper by Daniel Hoornweg and Kevin Pope, which projected the populations of the world’s biggest cities by 2100.
The standout example is that of Lagos, Nigeria, which went from under 200,000 people in the 1960s to an estimated 20 million people today. Though, I would imagine that the ubiquity of informal settlements makes it difficult to come up with an accurate number.
Still, it is one of the world’s top 10 largest cities and, by 2100, it may be the largest city in the world. The Guardian described the population as young, fertile, and increasingly urban. The median age in Nigeria is 18 and the fertility rate for the content is 4.4 births per woman.
I am mentioning all of this today because I think it grants some perspective. This is an immense city building challenge, not only because of the unprecedented growth rate, but also because it remains largely poor. Lagos, a city, may add more than 2.2x the population of Canada, a country, during the balance of this century.

The City of London Corporation recently published a report called “The City as a Place for People”, which talks primarily about itself and how great London is as a magnet for talent.
But as self-serving as it may be – the report is timed to be ahead of this year’s MIPIM – there appears to be some data and interviews backing up the claims.
58% of “institutional investors” said that London is the best European city for business. Dublin was next at 22%.
A separate survey of 2,568 “corporate decision makers” in Europe revealed that 21% of respondents felt that London was the best European city for business, followed by Paris (13%) and Frankfurt (7%). When asked which city had the best talent pool, the responses were fairly similar.
Also included in the report is a rendering of the City’s skyline by 2026. These are always fun to see. Here is a screen grab:
