Many American cities, described commonly as urban cores, are functionally more suburban and exurban, based on urban form, density, and travel behavior characteristics. Data from the 2010 census shows that 42.3 percent of the population of the historical core municipalities was functionally urban core (Figure 1). By comparison, 56.3 of the population lived in functional suburbs and another 1.3 percent in functionally exurban areas (generally outside the urban areas). Urban cores are defined as areas that have high population densities (7,500 or per square mile or 2,900 per square kilometer or more) and high transit, walking and cycling work trip market shares (20 percent or more). Urban cores also include non-exurban sectors with median house construction dates of 1945 or before. All of these areas are defined at the zip code tabulation area (ZCTA) level, rather than by municipal jurisdiction. This is described in further detail in the “City Sector Model” note below.

The very centers of urban cores in many major metropolitan areas are experiencing a resurgence of residential development, including new construction in volumes not seen for decades. There is a general impression, put forward by retro–urbanists and various press outlets that the urban core resurgence reflects a change in the living preferences of younger people – today’s Millennials – who they claim are rejecting the suburban and exurban residential choices of their parents and grandparents.
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 fortunes of U.S. core cities (municipalities) have varied greatly in the period of automobile domination that accelerated strongly at the end of World War II. This is illustrated by examining trends between the three categories of “historical core municipalities” (Figure 1). Since that time, nearly all metropolitan area (the functional or economic definition of the city) growth has been suburban, outside core municipality limits, or in the outer rings of existing, core municipalities.
Today, more than any time, arguably, since the Great Depression, the prospects for improved housing outcomes are dimming for both the American middle and working classes. Not only is ownership dropping to twenty-year lows, there is a growing gap between the amount of new housing being built and the growth of demand.
Philadelphia was America’s first large city and served as the nation’s capital for all but nine months between the inauguration of George Washington is the first president in 1789 and the capital transferred to Washington, DC in 1800. Before the early 1900s, the United States Census Bureau had not developed a metropolitan area (labor market area) concept. However, the website peakbagger.com has attempted to define earlier metropolitan areas based on concepts similar to those used today. In the case of Philadelphia, this is important, because it was somewhat unique in having virtually adjacent, highly populated suburbs that make comparisons of municipal populations (the only population data available) misleading.
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.
There is an increasing recognition – at least outside the academy, planning organization and urban core developer groups – that the spatial expansion of cities or suburbanization represents the evolving urban form of not only the United States and virtually all of the high income world but also across the developing world, whether middle income or third world.
In recent years, Mexico has made substantial economic progress. Per capita income (purchasing power parity) in Mexico exceeds that of all the “BRIC” nations (Brazil, Russia, India, and China) except resource-rich Russia.
The 2013 annual metropolitan area population estimates by the US Census Bureau indicate a continuing and persistent dominance of population growth and domestic migration by the South. Between 2010 and 2013, 51 percent of the population increase in the 52 major metropolitan areas (over 1 million population) was in the South. The West accounted for 30 percent of the increase, followed by the Northeast at 11 percent and eight percent in the North Central (Midwest).
The American Public Transportation Association (APTA) is out with news of higher transit ridership. APTA President and CEO Michael Melaniphy characterizes the new figures as indicating “a fundamental shift going on in the way we move about our communities.” Others even characterized the results as indicating “shifting consumer preferences.” The data shows either view to be an exaggeration.
In a hard fought election campaign, voters in the city of Tigard appear to have narrowly enacted another barrier to light rail expansion in suburban Portland. The Washington County Elections Division reported that with 100 percent of precincts counted, Charter Amendment 34-210 had obtained 51 percent of the vote, compared to 49 percent opposed.
Despite planning efforts to restrict it, the Bay Area continues to disperse. For decades, nearly all population and employment growth in the San Jose-San Francisco Combined Statistical Area has been[…]
The term “Greater New York” was applied, unofficially, to the 1898 consolidation that produced the present city of New York, which brought together the present five boroughs (counties). When consolidated, much of the city of New York was agricultural. As time went on, the term “Greater” came to apply to virtually any large city and its environs, not just New York. By 2010, Greater New York had expanded to somewhere between 19 million and 23 million residents, depending on the definition.
