According to the new United Nations World Population Prospects: The 2015 Revision, the population of the world is projected to rise from 7.3 billion in 2015 to 11.2 billion in 2100. This represents a 53 percent increase. However, over the period, population growth will moderate substantially. This is indicated by the annual growth rate the first year (2015 to 2016), at 1.1 percent, compared to the last year (2099 to 2100) at 0.1 percent. Annual population growth is projected to decline 90 percent from the beginning of the period to the end (Figure 1).

For decades, California’s housing costs have been racing ahead of incomes, as counties and local governments have imposed restrictive land-use regulations that drove up the price of land and dwellings. This has been documented by both Dartmouth economistWilliam A Fischel and the stateLegislative Analyst’s Office.

America’s cities (metropolitan areas) changed radically since the dawn of World War II. At that point, cities were dominated by their core municipalities (central cities), around which people traveled much greater percentages by transit and lived in much higher densities. Automobile oriented suburbanization had increased rapidly in the 1920s, but was slowed by the economic upheavals of the 1930s.

Still Moving to Texas: The 2014 Metropolitan Population Estimates
by Wendell Cox March 30, 2015Texas continues to dominate major metropolitan area growth. Among the 53 major metropolitan areas (with more than 1 million population), Texas cities occupied three of five top positions in population growth, and four of the top 10 (Figure 1).

The headline line in the Sunday St. Louis Post-Dispatch asked “Are St. Louis Area’s Home Prices too Low?” This is could not possibly have appeared describing any major metropolitan area of Australia, New Zealand, or the United Kingdom. Nor will newspapers in Vancouver, Toronto, Calgary, Portland, Seattle, Boston, New York or in any of the overpriced markets of California decry low prices any time soon.

A few years ago, the satirical publication, The Onion ran an article under the headline “98 Percent of US Commuters Favor Public Transit for Others.” The spoof cited a mythical press release by the American Public Transit Association (APTA), in which Lance Holland of Anaheim, California said “Expanding mass transit isn’t just a good idea, it’s a necessity,” Holland said. “My drive to work is unbelievable. I spend more than two hours stuck in 12 lanes of traffic. It’s about time somebody did something to get some of these other cars off the road.”

America is getting older, as medical science prolongs life expectancy and the fertility rate hovers at or even below the replacement rate. One metric for gauging the nation’s aging is the median age – the age at which one half the population is younger and the other half is older. In 2000, the median age in the United States was 35.3. By 2013, the median age had increased to 37.5.

Americans continue to favor large houses on large lots. The vast majority of new occupied housing in the major metropolitan areas of the United States was detached between 2000 and 2010 and was located in geographical sectors associated with larger lot sizes. Moreover, houses became bigger, as the median number of rooms increased (both detached and multi-family), and the median new detached house size increased.

The newly released American Community Survey data for 2013 indicates little change in commuting patterns since 2010, a result that is to be expected in a period as short as three years. Among the 52 major metropolitan areas (over 1 million population), driving alone increased to 73.6% of commuting (including all travel modes and working at home). The one mode that experienced the largest drop was carpools, where the share of commuting dropped from 9.6% in 2010 to 9.0% in 2013. Doubtless most of the carpool losses represented gains in driving alone and transit. Transit grew, increasing from a market share of 7.9% in 2010 to 8.1% in 2013 in major metropolitan areas; similarly working at home increased from 4.4% to 4.6%, an increase similar to that of transit (Figure 1). Bicycles increased from 0.6% to 0.7%, while walking remained constant at 2.8%.

There is a general perception that the densest US cities are in the Northeast, where downtowns tend to be bigger and inner city densities are higher. However, cities have become much larger geographically, and also include the automobile oriented lower density suburbs that have developed since World War II. In fact, most of the densest major urban areas are in the West.

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.
