The front cover of Engineering News-Record on March 12th, 2012 was about a technology survey conducted a few weeks earlier. Of 18 issues surveyed, the need for better software was mentioned most frequently. Under read more »
The recent release of the 2010 US census data on urban areas (Note 1) shows that Americans continue to prefer their lower density lifestyles, with both suburbs and exurbs (Note 2) growing more rapidly than the historic core municipalities. This may appear to be at odds with the recent Census Bureau 2011 metropolitan area population estimates, which were widely mischaracterized as indicating exurban (and suburban) losses and historical core municipality gains. read more »
The Recovery Blueprint is a multipart series of articles that offers suggestions on how to recover from the homebuilding recession.
Since the recession began, there haven't been any significant changes in how regulations could be improved to energize the housing market and foster innovation. Three areas where big regulation changes are needed? Environmental subsidies, density requirements, and zoning laws. read more »
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 »
Recently the Census Bureau released 2011 county and metro area population estimates that showed overall slowing population growth and particularly showing slow to halting growth in exurban counties.
Someone once said to me about Chicago’s Mayor Daley that if he did something you liked, he was a visionary genius leader, but if he did something you hated, he was a corrupt machine dictator.
That seems to be how too many urbanists view the Census Bureau. read more »
My April 9 Cross Country column commentary in The Wall Street Journal (California Declares War on Suburbia) outlined California's determination to virtually outlaw new detached housing. The goal is clear: force most new residents into multi-family buildings at 20 and 30 or more to the acre. read more »
Population growth in Australia is double the world average and the New South Wales Department of Planning has projected that the population of the Sydney region will increase by 57,000 people annually. How will these extra people be housed? The NSW Government follows the usual doctrines based on higher population densities. Its planning policy, known as The Metropolitan Strategy, works on locating some 70% of new dwellings within existing urban communities (in-fill) and 30% in new greenfield sites. read more »
The urban population of the United States is now 249 million, according to the 2010 Census, 81 percent of the total. This is impressive, and not all surprising for a large developed economy. Yet the urban population --- meaning cities, suburbs and exurbs --- is not everything. And in many ways for everything from food, resources and recreation, the urban areas still depend on the nearly sixty million who live in rural America read more »
The new 2011 Census Bureau county and metropolitan area population estimates indicate that Americans are staying put. Over the past year, 590,000 people moved between the nation's counties. This domestic migration (people moving within the nation) compares to an annual rate of 1,080,000 between the 2000 and 2009. Inter-county domestic migration peaked in 2006 at nearly 1,620,000 and has been falling since that time (Figure 1). read more »
