So here's the headline: More people are moving to Manhattan than before the pandemic. This is true. But an even more accurate description might be that New York City was losing people before the pandemic and it is still losing people. But things have rebounded since the lows of the pandemic and it is now losing less people. Here are two charts from Bloomberg:
This is generally good news since the increased exodus (to places like Miami) led some to believe that one of the most important global cities in the world was now dying. I never thought that was the case. But there's no arguing against the fact that the fastest growing cities in the US are the ones with more affordable housing and fewer constraints on new development.
These are a set of diagrams taken from a recent WSJ article talking about how, "the pandemic changed where Americans live." I know that this is a topic that gets a lot of air time (both here on the blog and elsewhere), but these diagrams do a good job of showing the flow of people, as well as how things may have changed/accelerated since 2018.
These diagrams also remind me of the work of Charles Joseph Minard. A French civil engineer, Minard is best known for his contributions to the field of information graphics, and in particular his flow maps. His most famous piece of work -- which I happen to have hanging at home -- is his depiction of Napoleon's losses during the Russian campaign of 1812.
The map itself is from 1869 and is packed full of information. It shows the number of Napoleonic troops as they left for Moscow, the distance they traveled, the outside temperature (the French weren't properly prepared for the cold), latitude and longitude, the direction of travel, and the location of the troops relative to specific dates.
The point of the diagram was really to show how disastrous this campaign was for Napoleon. The thick beige band on the left is showing over 400,000 troops setting out. But by the time they reached Moscow -- which, by the way, had been abandoned before their arrival -- only about 100,000 troops were left.
The thin black bar on the bottom is showing how many troops ultimately remained and returned at the end of the campaign -- the number was only about 10,000. So the vast majority of Napoleon's troops perished. Supposedly over half either starved or froze to death.
Some 150 years later, and we are still using flow charts to clearly depict the movement of people and things.
I can't open Twitter these days without seeing someone in the tech industry talking about moving or talking about someone who just moved to either Austin or Miami. "What's the best neighborhood in Miami for startups? My friend just moved to Edgewater. Where did so-and-so move?"
Here's a recent article from the WSJ talking about how accelerated tech-fueled growth is straining Austin. And below is a set of charts (from the article) comparing home prices in Austin and San Francisco. (Reminder, the California-to-Texas migratory pattern recorded the highest number of "net movers" last year.)
But in reading through the article, I am reminded that the challenges facing Austin are not entirely unique. Growing cities all around the world are being put in a position where they need to decide whether they want to remain car-oriented and relatively low-density, or if they want to make the shift toward more transit-oriented urbanism.
It's admittedly not easy, both politically and practically speaking. It's hard to rewrite deeply entrenched built form. But Austin is naturally looking at what happened in San Francisco, where restrictions on new development are thought to be partially (largely?) responsible for the city's unaffordable housing.
According to the same WSJ article, voters in Austin turned down two previous transit proposals. One was in 2000 and the other was in 2014. There was concern over too much urbanization. There was concern it would induce more people to move to the city. And there was concern that it would threaten the city's low-rise single-family homes.
But this year a transit plan was approved that includes three new rail lines, one of which will tunnel through downtown. Provided that Austin can effectively pair this with more housing, more uses, and more density -- which is generally what you need to make transit work -- then it may be well on its way to crossing, if you will, the chasm of urbanity.
