Demographics

For more than 15 years, New York State has led the country in domestic outmigration: for every American who comes to New York, roughly two depart for other states. This outmigration slowed briefly following the onset of the Great Recession. But a new Marist poll released last week suggests that the rate is likely to increase: 36 percent of New Yorkers under 30 are planning to leave over the next five years.  read more »

A new Brookings Institution report provides an unprecedented glimpse into the lack of potential for transit to make a more meaningful contribution to mobility in the nation's metropolitan areas. The report, entitled Missed Opportunity: Transit and Jobs in Metropolitan America, provides estimates of the percentage of jobs that can be accessed by transit in 45, 60 or 90 minutes, one-way, by residents of the 100 largest US metropolitan areas.  read more »

The Auckland Council’s great vision is to make Auckland one of the world’s most livable cities. Yet the outcome of its currently proposed plans will be a city which is second best for most Aucklanders.

Some 60% to 80% of residents of New World cities state a clear preference for a single family home with its own backyard. In Victoria state, where Melbourne is located, 70% of the population, for example, preferred a single family home according to one government study. There have been similar findings from US based groups like the National Association of Realtors.  read more »

The “global city” is one of the dominant themes related to  urban success today.  In this model, cities serve both as huge agglomerations of top specialized talent and also as “control nodes” of the global economy serving as key sites for the production of financial and producer services demanded by the new globalized economy. In her seminal book on the subject, Saskia Sassen noted New York, London, and Tokyo as the paradigmatic examples of the global city.  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 »

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 »

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 »

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 »
