Cities have been pivotal role to improved living standards, because of the opportunities they facilitate. This is particularly evident over the past two centuries, as world urbanization has risen from 3 percent to over 50 percent, and to more than 80 percent in the United States.
Much attention has been given the increase in transit use in America. In context, the gains have been small, and very concentrated (see: No Fundamental Shift to Transit, Not Even a Shift). Much of the gain has been in the urban cores, which house only 14 percent of metropolitan area population. Virtually all of the urban core gain (99 percent) has been in the six metropolitan areas withtransit legacy cities (New York, Chicago, Philadelphia, San Francisco, Boston, and Washington).
The recently released 10th edition of Demographia World Urban Areas provides estimated population, land area and population density for the 922 identified urban areas with more than 500,000 population. With a total population of 1.92 billion residents, these cities comprise approximately 51 percent of the world urban population. The world’s largest cities are increasingly concentrated in Asia, where 56 percent are located.
Time Magazine’s Sam Frizell imagines that the American Dream has changed, in an article entitled “The New American Dream is Living in a City, Not Owning a House in the Suburbs.” Frizell further imagines that “Americans are abandoning their white-picket fences, two-car garages, and neighborhood cookouts in favor of a penthouse view downtown and shorter walk to work.” The available population data shows no such trend.
There was a time when downtown Los Angeles was the commercial center of Southern California. According to Robert Fogelson, writing in his classic Downtown: Its Rise and Fall (1880-1950)”nearly half” of Los Angeles residents went downtown every day in the middle 1920s. A time traveler from 1925 might think that to still be the case, with the concentration of tall buildings, and the frequent press reports about downtown’s resurgence.
