But the big factor that doesn’t seem to be well-understood is simple population math. College attendance has climbed over the years to the point where an overwhelming majority of American young people will enroll in college of some kind at some point. This makes college enrollment extremely sensitive to fluctuations in the number of young people available. The generation currently in college or recently out of it is one of the largest this country has managed to produce. It’s no wonder there was a spike in enrollment, recession or no, back in 2008-09 if one looks at the number of Americans who were just reaching 18-19 years of age. Since then those numbers have fallen sharply and will continue to fall more slowly for the foreseeable future as the U.S. birth rate hovers below replacement (on a positive note, most of that decline is attributable to a precipitous decline in teen pregnancy).
Here is the United States’ population by age from 2010-2013.
An article at the Urbanophile gives us a helpful graphic explaining the old and new “Donut” conceptions of the city. In the “Old Donut,” we have an impoverished central city with a ring of thriving suburbs around it.
An example of that model appears in this graph, which shows the percentage of adults over 25 with college degrees in the Charlotte, NC metro area in 1990. The x-axis is distance from the center of downtown.
There is a lot of buzz amongst urbanists and demographers about millennials’ preference for urban areas. We’ve found evidence to support this narrative in some areas of Virginia, including indications that they may be staying even after having kids.
But there’s also a lot of talk about baby boomers retiring and moving into cities. Maybe this is happening in other parts of the U.S., but it’s certainly not the case in Virginia. On the contrary, they appear to be heading for the hills. In fact, despite Forbes Magazine naming Virginia its 5th best state to retire in, Virginia does not appear to attract many retirees in general.
Virginia is aging quickly, as can be seen on the map below. From 2000 to 2010, the median age in the Commonwealth rose from 35.7 to 37.5. In some localities, it rose by as many as 5 or 6 years in just that 10-year period. But most of that is due to a gradual decline in birthrates, not older people moving in. From 2000 to 2010, migration accounted for only a slight (1-2%) increase in the population of age groups around retirement age, and that increase was smaller than the state’s overall growth rate.
Local governments across the country have come under increasing fiscal strain in recent years, with several being forced to declare bankruptcy. The problems range from pension programs and decaying infrastructure to falling revenues from industrial and sales taxes as manufacturing gets offshored and shopping happens online. In Virginia, cities are further constrained by annexation laws that prevent them from expanding with their metropolitan area and gaining revenue from greenfield development or wealthier suburbs.
Recently, the Bureau of Labor Statistics published a map of industry sectors with the highest employment by state over the past couple of decades. The map shows clearly America’s shift from manufacturing to retail to healthcare. Retail trade has led in Virginia since 1996, even as the rest of the states have been taken over by healthcare.
In his 2014 State of the Union address, President Obama called on Congress to “give American a raise” by increasing the federal minimum wage. For the second year in a row he argued “that in the wealthiest nation on earth, no one who works full time should have to live in poverty”. Even with the presidential priority of raising the Federal minimum wage, the 2014 House bill was voted down. In spite of this, many states and cities have opted to raise the basic hourly wage independent of the federal government.
Raising the minimum wage will impact employers and employees alike, and through them the larger society. While fewer than three percent of US workers* earn the minimum wage (or less), 18 percent earn less than $10.10/hour (the amount proposed by the President). Understanding how an increased minimum wage will affect individuals first requires examining common arguments about low-wage workers.
Like many people, I’ve been inclined to explain Virginia’s decades of explosive population growth in terms of migration and the Federal government’s expansion in Northern Virginia. While that’s certainly part of the equation, “natural increase” has actually driven most of the growth, just as it has across the country. Natural increase simply means more people are born than die in a year. Even in Northern Virginia and Hampton Roads, natural increase is the largest generator of population growth. But “natural increase” does not mean that we are having lots and lots of babies. In fact, it has much more to do with the fact that we had a lot of babies a while back and since then people started living a lot longer.
You hear, on this blog and elsewhere, about the “aging population,” but I wanted to show exactly what that means. Here’s the one gif you need to see to understand population growth in Virginia:
Recently, I’ve been comparing a number of traits of metropolitan areas based on distance from the core. Here I’m looking at the average densities of each metro area as you travel outwards from the center, calculated using census blocks and 2010 short-form census data. I’ve graphed them in groups of three. Cities with a strong core will have high densities on the left (near the center) that fall off as you travel outwards. Cities whose densities fall off quickly on the right have clearer edges, while those that taper off slowly are more spread out. Click on the graphs to view them full screen.
First are the three major metro areas. Note that the Northern VA graph includes only Virginia census blocks, not the rest of the DC area. Northern VA has the largest population by far, with fairly high densities even several miles into the suburbs. Richmond has the smoothest curve. I used downtown Norfolk as the core for Hampton Roads, but the area’s polycentricity is obvious.
