Urban Issues

The Alternate Clean Transportation Expo held in Long Beach earlier this month was a spectacular display of engineering ingenuity by Natural Gas Vehicle providers. The event's theme was that America’s self sufficiency in natural gas has decoupled our energy resources from petroleum prices. But the consensus among the gathered engineers and scientists was to look beyond the current prices of petroleum alone, and consider that domestic self sufficiency includes keeping jobs at home.  read more »

Are compact cities healthy cities? One argument for compact cities is that they are good for our health.  The New Zealand Public Health Advisory Committee in 2008, for example, cited four principles for healthy urban planning based on the density of development: urban regeneration, compact growth, focused decentralisation, and linear concentration.  The aim is less time in cars and more use of active transport.  read more »

Perhaps the most surprising development in urban areas over the past year was the ascendancy of Delhi to rank second in the world in population, following only Tokyo – Yokohama. Based upon the new United Nations population estimate, the 7th annual edition of Demographia World Urban Areas places Delhi's population at 22.6 million.  read more »

For nearly a generation, the information sector, which comprises everything from media and data processing to internet-related businesses, has been ballyhooed as a key driver for both national and regional economic growth. In the 1990s economist Michael Mandell predicted cutting-edge industries like high-tech would create 2.8 million new jobs over 10 years.  This turned out to be something of a pipe dream.  read more »

Detroit, not only in the US but across the globe, has become the poster child for urban decay.  The city lost 25% of its population between 2000-2010, and over half its population since 1950.  Over 90,000 houses stand empty, and many neighborhoods have been completely abandoned.   read more »

A new census leads us to ask how population has changed, but usually discussion is focused on changes since the last census. But even more interesting is to appreciate the vaster changes over a greater sweep of time, for example: the fifty years since 1960, when the United States had 179 million people, toward the end of the post-war Baby Boom.  read more »

Beauty is in the eye of the beholder. And most people who drive through blocks of industrial urban neighborhoods in Queens County, New York find them ugly, depressing, and sometimes dangerous. I spend a great deal of time in these kinds of neighborhoods, and to the shock and surprise of many - especially my close friends and family - I find them just as interesting and usually more exotic than the overly-planned communities touting the new urbanism popping up all over the country.  read more »

For years, demographers have been predicting that the population of Japan would begin to decline. The  census of Japan, conducted every five years, however, still continues to show slight population growth, with 288,000 people having been added between 2005 and 2010. This growth was so small that the nation of Japan added fewer people than seven US metropolitan areas (Dallas-Fort Worth, Houston, Washington, Atlanta, Riverside-San Bernardino, Phoenix and Raleigh) and less than the Toronto metropolitan area over the same period of time.  read more »

This year’s survey of the best cities for jobs contains one particularly promising piece of news: the revival of the country’s long distressed industrial sector and those regions most dependent on it. Manufacturing has grown consistently over the past 21 months, and now, for the first time in years, according to data mined by Pepperdine University’s Michael Shires, manufacturing regions are beginning to move up on our list of best cities for jobs.  read more »

Dramatic shifts in population growth across the United States in the last decade should surprise no one. Some patterns are continuing trends of earlier decades, but other patterns show substantial change.  I show these changes in three ways, first a conventional choropleth map coloring counties by broad classes from high losses to moderate and high percent gain, second a map in which absolute gains and losses are depicted by proportional symbols, with colors showing the rate of change, and third, a look a counties that experienced either extreme loss and gain.   read more »
