Sprawl since the 1970s
During the last several decades of the twentieth century, cities across the world have had a prodigious growth both in population and land area. Where historically only a few cities anywhere reached a population of a million people, by the end of the twentieth century, China alone had more than thirty cities with a million people—many of them places that few people in the Western world have ever heard of. The largest metropolitan areas today, places like Tokyo-Yokohama, New York City, and Mexico City now number over 20 million people and sprawl across vast territories, incorporating in their urbanized area freeways, shopping centers, industrial parks, subdivisions, airports, and many previously separate urban entities. The most affluent of these, for example, the region from Tijuana in Mexico to Santa Barbara in Southern California, can extend for over one hundred miles, contain more inhabitants, and boast a larger economy than all but a few nations.1
