A couple of months ago I took the blog for a visit to the airport to check out historical passenger data and see what’s happened since COVID. Today I want to return, both to provide an update and to pull YVR Passenger data (enplaned & deplaned pdf) together with BC CDC Flight Exposure data (full pdf), providing a check on air travel’s contributions to spreading COVID.
We now have over six months of pandemic conditions in Vancouver and crime data to (roughly) match. We also have all kinds of claims about crime flying around, sometimes pushed by the police (VPD) themselves, only heightened by click-seeking reporters and the vote-seeking politicians. So we should probably check into the data. Long story short: there’s scant evidence of a crime wave showing up in the VPD crime data.
People move. That includes people who end up getting counted as homeless. How should we interpret what homeless counts tell us about these people?
To an important extent, this question brings us back to fundamental interpretations of who gets counted. Is being counted as “homeless” interpreted as a social problem: the lack of enough accessible housing? Or is it being interpreted as a person problem: identifying the “homeless” as fundamentally different from housed people?

Do people select cities from diverse alternatives? Or do cities select residents from diverse flows of people?
The answer is pretty much: both. Continue reading
So, what’s happening at the airport these days?
Here in Vancouver (or more specifically, Richmond), I discovered that YVR actually posts some of their data. This is great! I’m going to look at their recent passenger data to get a sense of two things. First, how much air travel into and through Vancouver has grown in recent years. Hello globalization! Second, how much air travel into and through Vancouver has shrunk in recent months. Hi there world-wide pandemic! Continue reading
I’m currently enjoying Desmond Fitz-Gibbon’s Marketable Values: Inventing the Property Market in Modern Britain. It’s a fascinating book on how British real estate was transformed from estates granted and traded in private transactions bound by custom (think of landed nobility but also the Commons pre-enclosure) into something that could be bought and sold at auction and described in terms of a market, mostly over the course of the late 18th and 19th Centuries.
I was curious about this book for lots of reasons, not least because it seemed British property practices often spread to colonies, as in Canada. But as described by Fitz-Gibbon, this was actually a two-way street, and experiences in real estate at the peripheries of Empire also often informed practices back in England. Continue reading
Why do people move? I’ve taken up this question in a series of recent posts (some co-authored), and though the available data to address the question remains sparse, it’s getting richer all the time. Today I want to compare three different sources of information, highlighting how much it matters just how we ask people about their reasons for moving. Continue reading
Sometimes we talk about cities as if they’re settlements, where people become fixed to place. But in fact, if you track movements of people, cities look more like rivers. People churn through the urban landscape. Net migration numbers are really useful in some contexts, but also obscure the full extent of this churning. Fortunately, BC Stats has numbers that attempt to break down actual flows of people through regions. We can break out Metro Vancouver (a.k.a. Greater Vancouver) and see just how many people we think might be flowing through. Here’s a little graphic I made to highlight this churn, while I continue playing around with the best way to present it. Continue reading

When people want to live in your city, how many should you let in? On the one hand, this is a moral question. Do you have an obligation to people who don’t already live here? On the other hand, it’s a moot question. At least in Canada, cities don’t have the power to control migration. Continue reading

In our previous post on COVID mortality in context, we tried to place COVID deaths, as recorded so far this year, in the context of expected deaths from previous years. There have been a lot more developments since that post. And unfortunately a lot more deaths too. Continue reading
