The surprising math of cities and corporations

"Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities — that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city's population. In this mind-bending talk from TEDGlobal he shows how it works and how similar laws hold for organisms and corporations."

While corporations rise and fall, it is quite rare for a city to entirely fail as an economic system.  Huge cities have some negative consequences, but the networks that operate in the city function more efficiently on economies of scale in a way that offsets the negatives.  Increasing a city's population will continue to improve the economies of scale (larger cities have higher wages per capita, more creative employment per capita, etc.).  However, this growth requires major technological innovations to sustain long-term growth.

Not surprisingly the DNA of cities is a follow-up of human DNA and understanding this will explain and predict how the body of a city will develop!

SRA's curator insight, April 16, 2:10 AM

The idea that cities are just organisms that are satisfying the laws of biology is interesting. Especially because Physicist Geoffrey West brings the idea of Scalability which by definition is, the ability of a system, network, or process to handle a growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth. What’s mind blowing to me is that the system that is referred to here is human interaction.  We create these cities through our interaction and experience. With a growth rate of 1,000,000 people every year the math adds up to an agreeable 15% rise in income levels, patents, and super creative people every year which is undoubted a win for civilization and society. But with that we must keep in mind also this means a 15% increase in things like deadly disease, crime, poverty, and ecological issues leading to further degradation of our planet. This unbounded growth means the system is destined to collapse. The math behind cities doesn't lie if we don’t prepare cities have a fate to die like every other organism in Biology. So it is up to us to create and innovate to sustain this growth and avoid the collapse. But we must do so at a forever increasing pace. Which subsequently is also part of another system predetermined to collapse. What I mean is what happens when we cannot innovate fast enough to sustain this growth?

Visualizing Regional Population Statistics

It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.


This is an excellent video for population and demographic units, but also for showing regional and spatial patterns within the global dataset (since terms like 'overpopulation' and 'carrying capacity' inherently have different meanings in distinct place and when analyzed at various scales). It is also a fantastic way to visualize population data and explain the ideas that are foundational for the Demographic Transition Model.

This video describes and explains how we got to a population of 7 billion people so fast

It also uses water to demonstrate it.
