Philadelphia

Jean Gottman in 1961 coined the term megalopolis (Megalopolis, the Urbanized Northeastern Seaboard of the Unites States) to describe the massive concentration of population extending from the core of New York north beyond Boston and south encompassing Washington DC. It has been widely studied and mapped, including by me. (Morrill, 2006, Classic Map Revisited, Professional Geographer).  The concept has also been extended to describe and compare many other large conurbations around the world.

Maybe it’s time to see how the original has fared?   And what has happened to other metropolitan complexes in the US, most notably Los Angeles, San Francisco, Chicago and should we say Florida?  read more »

The 2010 Census results were mostly bleak for cities, especially for those who believed the inflated hype about the resurgence of the city at the expense of the suburbs.  Despite claims of an urban renaissance, the 2000s actually turned out to be worse than the 1990s for central cities.  The one bright spot was downtowns, which showed strong gains, albeit from a low base.  The resurgence of the city story seemed largely fueled by intra-census estimates by the government that proved t  read more »

In defiance of the conventional wisdom in the national media and among most planning professionals, Americans continue not only to prefer, but to move into single family detached houses. Data from the 2010 American Community Survey indicates that such housing attracted 79.2% of the new households in the 51 major metropolitan areas (over 1,000,000 population) over the past decade.  read more »

Black population changes in various cities have been one of the few pieces of the latest Census to receive significant media coverage.  The New York Times, for example, noted that many blacks have returned to the South nationally and particularly from New York City.  The overall narrative has been one of a “reverse Great Migration.”  But while many northern cities did see anemic growth or even losses in black population, and many southern cities saw their black population surge, the real story actually extends well beyond the notion of a monolithic return to the South.  read more »

The state of New Jersey virtually defines suburbanization in the United States.  New Jersey is not home to the core of any major metropolitan area but, major portions of the nation's largest metropolitan area (New York) and the fifth largest metropolitan area (Philadelphia) are in the state (See map). These two metropolitan areas comprise 17 of the state's 21 counties. Another county (Warren) is in the Allentown, Pennsylvania metropolitan area, while Atlantic (Atlantic City), Cumberland and Cape May are single-county metropolitan areas.  read more »

For a decade now U.S. city planners have obsessively pursued college graduates, adopting policies to make their cities more like dense hot spots such as New York, to which the "brains" allegedly flock.

But in the past 10 years "hip and cool" places like New York have suffered high levels of domestic outmigration. Some boosters rationalize this by saying the U.S. is undergoing a "bipolar migration"--an argument recently laid out by Derek Thompson in The Atlantic.  read more »

The first decade of the new millennium was particularly hard on the US economy. First, there was the recession that followed the attacks of 9/11. That was followed by the housing bust and the resulting Great Financial Crisis, which was the most severe economic decline since the Great Depression.  read more »

On a recent whirlwind through Pennsylvania, I thought of James Carville, who popularized the notion that “It's Philadelphia on one side, Pittsburgh on the other, and Alabama in the middle.” It’s a clever line, but between the Ohio and Delaware rivers he is missing a great American tapestry: the wreck of the Penn-Central, United flight 93’s final frantic moments, the social history of the Johnstown flood, and whether a state of steel and coal is past or present.  read more »

On schedule, the annual ritual occurred last week in which the Census Bureau releases population and migration estimates and the press announces that people are no longer moving to the Sun Belt. The coverage by The Wall Street Journal was typical of the media bias, with a headline “Sun Belt Loses its Shine.” In fact, the story is more complicated – and more revealing about future trends.

Domestic Migration Tracks Housing Affordability: There have been changes in domestic migration (people moving from one part of the country to another) trends in the last few years, but the principal association is with housing affordability.  read more »

Cuyahoga County Treasurer Jim Rokakis, who is based in Cleveland, estimates that new census numbers might show Cleveland's population to be 325,000, a whopping 153,000 drop in 10 years! That would be an average of 15,000 people leaving Cleveland every year.

That’s 1,250 people jumping ship every month,

312 people fleeing the wreckage every week,

45 people evacuating every day, or

2 people running out of Cleveland every hour, 24/7, the whole year, for 10 straight years.  read more »
