From a Stewart Brand presentation, via Tim O’Reilly:
O’Reilly Radar > A World Made of Cities (
1):
Every week in the world a million new people move to cities. In 2007 50% of our 6.5 billion population will live in cities. In 1800 it was 3% of the total population then. In 1900 it was 14%. In 2030 it’s expected to be 61%. This is a tipping point. We’re becoming a city planet.
One of the effects of globalization is to empower cities more and more. Communications and economic activities bypass national boundaries. With many national governments in the developing world discredited, corporations and NGOs go direct to where the markets, the workers, and the needs are, in the cities. Every city is becoming a “world city.” Many elites don’t live in one city now, they live “in cities.”
Massive urbanization is stopping the population explosion cold. When people move to town, their birthrate drops immediately to the replacement level of 2.1 children/women, and keeps right on dropping. Whereas children are an asset in the countryside, they’re a liability in the city. The remaining 2 billion people expected before world population peaks and begins dropping will all be urban dwellers (rural population is sinking everywhere). And urban dwellers have fewer children. Also more and more of the remaining population will be older people, who also don’t have children.
I conjured some with a diagram showing a pace-layered cross section of civilization, whose components operate at importantly different rates. Fashion changes quickly, Commerce less quickly, Infrastructure slower than that, then Governance, then Culture, and slowest is Nature. The fast parts learn, propose, and absorb shocks; the slow parts remember, integrate, and constrain. The fast parts get all the attention. The slow parts have all the power.
I found the same diagram applies to cities. Indeed, as historians have pointed out, “Civilization is what happens in cities.” The robustness of pace layering is how cities learn. Because cities particularly emphasize the faster elements, that is how they “teach” society at large.
Interestingly, the lesson of the 2004 US election was not about red states vs blue states or “moral values” but about urban vs rural voters. Progressive, tolerant, diverse values are more likely to be found in cities (as well as in the people who live there).
I haven’t read this through but that section jumped out at me, especially as I remembered the election analysis/post-mortem.
