Cities are technological artifacts, the largest technology we make. Their impact is out of proportion to the number of humans living in them. As the chart above shows, the percentage of humans living in cities averaged about one or two percent for most of recorded history. (The chart’s Y axis is a logarithmic scale of percentage.) Yet almost everything that we think of when we say “culture” arose within cities. After all, the terms “city” and “civilization” share the same root. But the massive citification, or urbanization, that characterizes the technium today is a very recent development. Like most other charts depicting the technium, not much happens until the last two centuries. Then populations booms, innovation rockets, information explodes, freedoms increase, and cities rule.
