Throughout US history, economic growth has typically spurred an “enormous reallocation of population.” Here is a graph from a recent New York Times article called: What Happened to the American Boomtown?

The argument, here, is that restrictions on development have made it so that the most prosperous cities are actually the slowest growing cities in terms of population. Here is a chart, from the same article, comparing population growth to average annual pay:

And here is an excerpt:

But these productive places aren’t growing as fast now as economists believe they should — and as they would if they didn’t impose so many obstacles on new development. Since the 1970s, land use restrictions have multiplied in coastal metros, making it harder to build in, say, San Jose, Calif., than in Phoenix. And the politics of development have become tense, too. In the Boston suburbs, the Bay Area, Brooklyn and Washington, people who already live there have balked at new housing for people who don’t.

We often talk about the impact of land use restrictions on supply and overall housing affordability. But here is an argument that it could also be impacting upward mobility.

I was listening to The Urbanist (Monocle Radio) last night while I was making dinner and there was a segment on Moscow’s “illegal retail kiosks.” These are small scale retail structures that were built without formal planning permissions and so the city decided to demolish them. 

There was lots of backlash. Photos here.

Now, I’ve never been to Moscow. So I can’t really comment on the attractiveness and usefulness of these kiosks. But I suspect that these illegal retail kiosks, many of which seem to have been located around metro stations, contributed quite a bit to the city’s urban vibrancy. Retail is hard to get right. It doesn’t work everywhere.

All of this got me thinking about our tendency to sterilize and overplan cities. I’m not saying that planning is bad. It’s not. But I do think we should acknowledge that we don’t know everything about the future and that human ingenuity will undoubtedly unlock new things we never thought would be beneficial.

So how do we plan for the unplanned? Perhaps it starts with accepting the off-center. Here’s a quote from Anthony Bourdain (it’s all over the internet, but I can’t seem to find the original blog source):

I think that troubled cities often tragically misinterpret what’s coolest about themselves. They scramble for cure-alls, something that will ‘attract business,’ always one convention center, one pedestrian mall or restaurant district away from revival. They miss their biggest, best, and probably most marketable asset: their unique and slightly off-center character. Few people go to New Orleans because it’s a ‘normal’ city — or a ‘perfect’ or ‘safe’ one. They go because it’s crazy, borderline dysfunctional, permissive, shabby, alcoholic, and bat shit crazy — and because it looks like nowhere else. Cleveland is one of my favorite cities. I don’t arrive there with a smile on my face every time because of the Cleveland Philharmonic.

There’s value at the margins.

The Wall Street Journal recently published this article talking about how the young and educated are flocking to high-density urban areas all across the United States. Here’s a set of charts from the article:

There are many people who will point out – probably rightly – that despite the “return to cities” that we are currently seeing, the world is still suburbanizing. But, it doesn’t appear to be suburbanizing in quite the same way as it did for prior generations. There’s also a socioeconomic shift taking place.

As an example, and to drive home the point that it’s not just the expensive coastal cities that are seeing rising home prices, the WSJ article focuses quite a bit on Ohio City – a neighborhood in Cleveland. Here’s what has been happening:

In the Ohio City neighborhood, the median income skyrocketed to $93,000 from $23,000 since 2006, according to Ohio City Inc., a local nonprofit development group. Median home values shot up 800% since 2000 to $270,000, according to Ohio City Inc. Median rental prices in downtown Cleveland as a whole jumped 47% from late 2010 to late 2015, according to the Center for Population Dynamics at Cleveland State University.

These are pretty dramatic increases – though $270,000 feels cheap to someone from Toronto. Still, it speaks to a trend. You and I both know that Ohio City isn’t the only neighborhood seeing those sorts of numbers.
