Insights from Scale, by Geoffrey West

To sustain open-ended growth in light of resource limitation requires continuous cycles of paradigm-shifting innovations.

Geoffrey West

I recently finished reading this book (official title is Scale: the universal laws of growth, innovation, sustainability, and the pace of life in organisms, cities, economies, and companies, whew!) published in 2017. Somehow, I missed it when it first came out; I found a reference to it in something else I was reading. West is a former President of the Santa Fe Institute and a distinguished nuclear physicist – in spite of that his book is relatively easy reading.

The general basis of the book is that there are properties of cities that scale in certain ways with population. In general, infrastructure scales sublinearly with population. As an example, if we graphed miles of roads vs population of cities from around the world we’d get a line that would curve down from a straight line. In other words, the larger the city the fewer miles of road per person (Mathematically, road miles scales with population raised to the ~0.85 power, 1 being linear).

However, some properties do scale linearly with population. For example, “the total number of establishments in each city regardless of what business they conduct turns out to be linearly proportional to its population size. Double the size of a city and on average you’ll find twice as many businesses. The proportionality constant is 21.6, meaning that there is approximately one establishment for about every 22 people in a city, regardless of the city size. Similarly, the data also show that the total number of employees working in these establishments also scales approximately linearly with population size: on average, there are only about 8 employees for every establishment, again regardless of the size of the city.”

On the other hand, socioeconomic properties scale superlinearly (curve up from a straight line, with exponent ~1.15). “The larger the city, the higher the wages, the greater the GDP, the more crime, the more cases of AIDS and flu [and covid, as we saw during the pandemic], the more restaurants, the more patents produced, and so on, all following the “15 percent rule” on a per capita basis in urban systems across the globe.” Both what’s good and what’s bad about cities, in one mathematical relation!

This seems to imply that population growth leads to socio-economic growth indefinitely. But, as West points out, growth can’t go on indefinitely. Similar to Moore’s Law for computer chips (doubling in power every two years), eventually you come up against some physical limitation that slows down growth. Unlimited growth inevitably leads to collapse…unless…

And that leads to what I see as the most important reason to read the book: West’s insights on growth, innovation and change. Innovation leading to positive change can enable continued growth. Thus, West posits a sort of symbiotic relationship among the three.

“Change and, by implication, innovation, must occur in order to continue growing and avoid collapse. Growth and the continual need to be adapting to the challenges of new or changing environments, often in the form of “improvement” or increasing efficiency, are major drivers of innovation.”

He also has a valuable insight about the rate of transformation. He points out that communities trying to fundamentally change and rise above their peers must temper their desire with the knowledge that positive transformation can be a very slow process. “Perhaps the most salient feature is how relatively slowly fundamental change actually occurs. Cities that were overperforming in the 1960s, such as Bridgeport and San Jose, tend to remain rich and innovative today, whereas cities that were underperforming in the 1960s, such as Brownsville, are still near the bottom of the rankings. So even as the population has increased and the overall GDP and standard of living have risen across the entire urban system, relative individual performance hasn’t changed very much. Roughly speaking, all cities rise and fall together, or to put it bluntly: if a city was doing well in 1960 it’s likely to be doing well now, and if it was crappy then, it’s likely to be crappy still.” This is an interesting sort of echo of the Law of Conservation of Community Momentum.

In the book, West concentrates on the overall trends. However, the real opportunities for fruitful investigation by the rest of us are the outliers to the trends.

What communities have leapfrogged their peers? How have they done it? New Orleans after Katrina seemed to have done this in several areas, e.g., education. But now NOLA seems to be backsliding – reverting to the mean or even worse, especially in violent crime. I think this book is essential reading for those interested in our communities – both for the hidden relationships it reveals and for the food for thought it provides.

I read this appreciation of George Orwell this morning. Well worth your time.

The Roaring Twenties (and beyond)

It’s tough to make predictions, especially about the future.— Yogi Berra

This is the time of the year when all of the crackpots with crystal balls (most of them cloudy or cracked as well) try to predict the future. I’m going to join that crowded club (some might say I’m a charter member!) but I’m going to focus on communities.

Right away, you know that any predictions are going to be fuzzy – our communities are too diverse in size, in culture and in structure for any prediction to be universally true. Thus, I will highlight relevant trends for the coming decade (and beyond) and in a later post I’ll try to project how these trends will impact communities and their resilience.

Let me set the stage by taking a quick look back at the decade just past (the Twittering Teens?). Globally, it likely was the best decade ever. For the first time less than 10% of the world’s population was mired in extreme poverty. Global income and wealth inequality – especially in Africa – was reduced. Infant and child mortality fell to record lows. Famine became all but extinct. Malaria, polio and heart disease are all in decline globally. Globally, life expectancy continues to rise (except for middle and lower class white men in the US). The world also is on a more sustainable path – in much of the first world the use of resources to make “stuff” declined; not only on a per capita basis but on an absolute basis. Look at how little raw bauxite goes into aluminum cans now compared to 50 years ago, for example. We need much less land for food production – one-third to produce the same amount of food than was needed 50 years ago. Not to mention dolphins back in the Potomac for the first time since the 1880’s!

However, in the developed world there has been a growing sense of unease. The cultural clash between populism and statism – between Big Everything and the Little Guy – has become downright vicious. Brexit and Boris; Bernie and the Donald; the Elite and the Deplorables are manifestations of societies in which Big Everything (government, business, unions…) is all about the numbers and seemingly has lost the ability to care about – or even listen to – individual people. As a result, we see more and more anti-social behavior: little things like people making U-turns in the middle of a four lane road; bigger things like preventing speakers we don’t like from speaking. This has led to near-gridlock on the national level, which is trickling down to many communities.

This cultural clash has been compounded by social media that have devolved into echo chambers. From where we live to where our kids go to school to who we interact with on Facebook and Twitter to what we watch on TV, too many of us are only hearing what we already believe from those like ourselves. Too few of us are willing to listen to thoughtful people who see things from a different perspective. As a result, we seem to be stumbling around the problems that surround us because our ideological red- or blue-tinted glasses keep us from seeing those problems and their possible solutions in proper perspective.

Perhaps one of the most important trends for communities center around population. Toward the end of this decade, and especially in the next, the Baby Boomers will start to exit the stage. They’ll take with them their pension liabilities and their health issues. If communities can survive the pension woes coming this decade, they’ll likely have more to spend in the 2030’s.

However, many communities will have a hard time doing that. The exodus from the high tax states (e.g., CA, NY, IL and NJ – the ones with likely the most unkept promises to retirees) will continue. Florida, Texas and the other southern states, and some of those in the western US, will experience growing pains as they try to accommodate the newcomers (Austin’s problem with homelessness – and the city’s non-solutions – sounds like something from California.). Immigration will add to these stresses.

College towns are likely to feel an even bigger pinch. The much smaller generations born after 1965 will lead to closures of many institutions of higher education (one study predicts one in six), or mergers (one study predicts one in five). If the push for free public education reaches fruition, private IHEs – relying as they do on tuition – will put in a vise. In turn, this will reduce the financial, human and social capital of their home towns.

Economically, the US will – at best – muddle through; the economies of much of the rest of the developed world are essentially stalled. Even China’s amazing growth seems to be slowing. There likely will be another recession within the next five years in the US (maybe sooner; Europe is probably already there), with the potential to rival the Great Recession in impact. However, the Federal Reserve and other central banks (with their near-zero to negative interest rates) and national governments (with their mountains of debt) will have even more difficulty responding to this one; recovery will be even slower. And it appears that the policies of the Federal Reserve and other central banks will continue to punish savers and inadvertently promote wealth inequality. The coming recession will reduce the apparent wealth at the top end, tbough. I intend to examine the “wealth gap” in a later post – closing it in a wise manner could have a huge impact on our communities.

A recession will likely accelerate two other trends: business consolidation and the growth of e-commerce. The growth of government regulations and the pressure of global competition has led to a situation in which every major industry is dominated by only a few companies. Credit Suisse estimates that by 2025 over one-fourth of all the malls in the US will be closed. E-commerce will make up to at least half of the retail economy by the end of the decade. Recession, business consolidation and e-commerce together spell big trouble for small businesses. After the Great Recession, job growth was dominated by intermediate and large companies for the first time; generally smaller businesses have been the driver of recovery. And small businesses are the lifeblood of the downtowns of many small and intermediate size communities. They’re the ones who sponsor youth sports teams; notices about community events are posted in their windows; they are often the anchors for the community’s sense of place.

Small businesses are also the entry point for most young people into the workforce. Spain, Greece and our own experience in the Great Recession point to disproportionate youth unemployment (This is also an unintended consequence of raising the minimum wage). Some of these youth will become isolated from their communities; with the potential for increased crime and drug use.

In fact, youth unemployment, in fact all employment will continue its inexorable change. As my friend Andy Felts is fond of tweaking me about, AI (and, more broadly, automation) will continue to erode the need for low-skilled workers. Past revolutions/evolutions in the nature of work have generally led to the need for roughly the same workforce in terms of numbers, but very different skill sets. Less farmland needed for food production and consolidation have led to fewer farms and farmers. We frankly don’t know what the advent of self-driving trucks and cars may mean for employment of cab and truck drivers, for example.

And perhaps the least recognized trend – the compression of time: the accelerating pace of change. Our communities are being assailed by demographic and social change, changes to their economic and environmental landscapes, and most of all changing expectations by their members. These are coming at communities faster and faster. As pattern seekers, our community leaders generally expect to have as much time to respond to these changes as they had “the last time,” but that expectation is no longer valid. To adapt to these changes requires both time and a willingness to take action. This places a premium on a community’s ability to foresee change and think strategically. I’ve written about this before, but I’ll explore this further in a later post.
