Demographics

Race and ancestry, or countries/peoples of origin, are popular topics, with large amounts of data attempting to help us understand the ethnic nature of the country. In this paper I attempt a summary description of the intersections of race, ancestry, and genome, at the state level, but I hasten to emphasize that the “findings” are tentative, highly uncertain, and based on astoundingly unreliable data. I hope some readers may point the way to better data or safer interpretations.  read more »

The massive, ongoing surge of migrants and refugees into Europe has brought up horrendous scenes of deprivation, along with heartwarming instances of generosity. It has also engendered cruel remembrances of the continent’s darkest hours. But viewed over the long term, this crisis may well be the prelude to changes that could dissipate, and even overturn, some of the world’s most-storied and productive cultures.  read more »

Japan reached "peak people" in 2011, when its population reached 127.4 million residents. From that point, all trends point to significant population losses. But, there is by no means unanimity on the extent of those population losses. Population projection is anything but an exact science, and Japan provides perhaps the ultimate example.

For generations the broad swath of America along the Great Lakes has been regarded as something of a backwater. Educated workers and sophisticated industries have tended to gather in the Northeast and on the West Coast, bringing with them strong economic growth.  read more »

As its former rivals in Asia and Europe slip into torpor and even decline, America, almost despite itself, is recovering its perch as the world’s bastion and predominant power. This is all the more remarkable given that our government is headed by someone who largely rejects traditional ideas about American exceptionalism, preferring to “lead from behind.”  read more »

If there’s one thing that’s a nearly universal anxiety among cities, it’s brain drain, or the loss of educated residents to other places. I’ve written about this many times over the years, critiquing the way it is normally conceived.

Since brain drain seems to be a major concern in shrinking cities, I decided to take a look at the facts around brains in those places. Looking at the 28 metro areas among the 100 largest that had objective measures of shrinkage – in population and/or jobs – between 2000 and 2013, I looked what what happened to their educational attainment levels.  read more »

The election of Barack Obama promised to inaugurate the dawn of a post-racial America. Instead we seem to be stepping ever deeper into a racial quagmire. The past two month saw the violent commemoration of the Ferguson protests, “the celebration” of the 50th anniversary of the Watts riots, new police shootings in places as distant as Cincinnati and Fort Worth, and renewed disorder, tied to a police-related shooting, in St. Louis last week.  read more »

In the fall of 2005, many saw in postdiluvial New Orleans another example of failed urbanization, a formerly great city that was broken beyond repair.Yet 10 years after a catastrophe that drove hundreds of thousands of its citizens away, the metro area has made an impressive comeback.  read more »

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.  read more »

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 economist William A Fischel and the state Legislative Analyst's Office.  read more »
