As more families choose cities, governments are returning to the drawing board

8 April 2014

Urban areas import the young and export the old, the theory goes, or went. For decades, young people have come to Virginia’s urban areas to go to university or work, often moving out again when their children require more space or education, or when they retire. But, since the mid 2000s, a demographic change has slowed the conveyor belt of movement in and out of cities. More young families are staying in Virginia’s urban areas to raise their children and enroll them in local schools, fueling the strongest population growth many of Virginia’s urban areas have experienced since the 1950s.

Though many young couples in the past have started families while they lived in urban areas, a good number would move to suburban counties before enrolling their children in school. In urban school divisions such as Arlington County and Fredericksburg, fewer than 60 percent of children born in 1999 showed up in first grade in 2005. The large number of young families moving into suburban school divisions caused many more children to enroll in first grade in counties such as Spotsylvania and Chesterfield than were born there six years earlier.2005 Ratio

Today, many parents are staying put in urban areas, thanks to stricter mortgage regulations that make it hard for buyers to get a loan, and a difficult labor market that makes it hard for anyone to be sure of a job. One-third as many homes were sold in 2012 as in 2005 in Virginia. During the same period, the Census Bureau’s American Community Survey shows that the number of Virginia families with children who live in a rented  residence has increased 15 percent.

Turning Population Projections into Development Projections

27 March 2014

The Weldon Cooper Center, under contract with the Virginia Employment Commission (VEC), developed and released in 2012 the most recent round of official state population projections for Virginia.  These projections, consistent with others commissioned or developed in the past by the VEC, focus primarily on trends in the number of people currently living in Virginia and expected to live in Virginia ten, twenty, and thirty years from now

It’s one thing to think about growth in terms of numbers of people, but another to think about it in spatial terms – as the growth of physical urbanized areas.  For a while now, I’ve been working on a GIS model that will do that.  I’ve posted it before on my own blog, but since then I’ve cleaned it up and made it follow our regional population projections more rigidly.

Here’s a land cover raster (an image showing what primarily covers each 15Mx15M square of land) of Virginia in 2006.  All developed land is in red.  It’s a great image of the shape of our metro areas.

A Closer Look at MSA’s and Commuting

19 March 2014

As Hamilton noted when posting the map of updated Virginia Metropolitan Statistical Areas, the MSA’s are calculated with commuting statistics.  If more than 25% of workers in a locality commute to a nearby metropolitan area, that county is considered to be closely linked to it.  This is a useful cutoff point, but like all cutoffs, it is completely arbitrary.  I mapped five of the state’s largest MSA’s to show the degree to which their surrounding counties are dependent on them.  This is important to understand since a significant part of Virginia’s “rural” areas are becoming increasingly exurban – dependent on nearby urban economies rather than agriculture or local industries.  Again, 25% is the cutoff for inclusion in the MSA (see Hamilton’s map linked above).  That includes all workers commuting to one of the core counties of the MSA.  The “core counties” are not explicitly listed anywhere that we’ve been able to find, but there is a definition and by working backwards from the commuting numbers it’s not too hard to figure out.

Ancestry: Who do you think you are?

13 March 2014

Largest Ancestry: 2000

Census-2000-Data-Top-US-Ancestries-by-County 2

This is one of my favorite demographic maps. It was produced by the Census Bureau to show the most commonly reported ancestry for each county in the United States in 2000. Even though the data is over 13 years old, the map remains very popular.

Since a follow-up map for 2010 has not been produced yet, I thought it would be more than worthwhile to create this map using Census American Community Survey data.

Largest Ancestry: 2010

Including Unreported

The methodologies used in making the 2000 and 2010 ancestry maps are similar, but there is one important alteration in the 2010 map. Ancestries that can be logically grouped together were combined so they might be better represented on the map. For example, Scandinavian ancestries: Norwegian, Danish, Swedish and Finnish, are very common in the Upper Midwest. Individually, they are the most popular ancestries in only a few counties, but when grouped together, Scandinavian is the most common ancestry in over 70 Upper Midwest counties.

Virginia’s immigrants: Where do they come from and where are they now?

4 March 2014

The foreign-born, or immigrants, comprise more than 10% of the Commonwealth’s population.  Most of them are between 25 and 44 years of age. This young cohort is highly active both in terms of production (working) and reproduction (having children). The adult foreign-born, for example, make up 15% of the Commonwealth’s workforce; and a fifth of all native-born children below the age of 18 have at least one foreign-born parent. More details are available here.

Contributions of the foreign-born population to multicultural diversity can be explored in several ways; where they come from and where they stay plays a key role in this story. A hundred years ago, most foreign-born people were from European nations; today almost 80% of immigrants to Virginia originate form Asia or Latin America. The top five countries of birth for the contemporary foreign-born population are El Salvador, India, Mexico, Philippines and Korea.  What is also of significance is where these immigrants choose to live within Virginia.

Slide2The distribution of foreign-born people among Virginia’s 11 metropolitan areas (MSAs) can be seen in the map above. Close to 70% of immigrants can be found in Northern Virginia alone, with Hampton Roads and Richmond hosting about 10% each. Among the smaller MSAs, Charlottesville leads the pack with nearly 20,000 foreign-born individuals, many of whom are students, faculty or staff at the University of Virginia.  The non-metro, mostly rural areas are home to less than 3 percent of the foreign-born.

The map below shows the percentage of each MSA population that is foreign-born. Again, Northern Virginia leads the way, with nearly a quarter of its population being immigrants. Harrisonburg and Charlottesville MSAs have a high proportion (nearly 9%) of foreign-born people, closely followed by Winchester and Richmond (7%), and Virginia Beach and Blacksburg (6%).

What are the young people up to these days?

27 February 2014

Much has been made of the living preferences and economic situation of millenials.  In the current economy, most localities can expect to lose almost all of their brightest young people to college towns.  Whether these localities are able to lure these college graduates back is another story, and an important one since (many argue) it’s during the free-and-easy years after college that most young people will start businesses, launch careers, and develop regional networks and allegiances.

In this post, I’ll take a closer look at the people who were in their 20′s during the 2010 census.  That’s people born between 1980 and 1990.  As one might expect, those 80′s babies were reasonably well-distributed when the prior census was taken in 2000.  At this point, the millennials were anywhere from 10 to 19 years old.  There was an uptick in college towns (18 and 19 year-olds), but it wasn’t huge.  In fact, that uptick helps to balance out the number of millenials who were undergraduates during the 2010 census (20 and 21 year-olds).

Ten years later, some of those kids are still in college or graduate school, some are young professionals, some are in the military, some are in prison, and some have young families with several kids.

Virginia’s 2013 Metro Areas

24 February 2014

Metropolitan Statistical Areas (MSAs) or Metro Areas are perhaps the most common way to define an urban region. Because many urban areas cross into multiple localities, such as in Hampton Roads, MSAs are frequently used in the public and private sector to understand an urban area and its suburbs. Despite the widespread usage of MSAs, it is actually very difficult to find an up-to-date map of Virginia’s MSAs, which is why I created this updated map following the 2013 definitions from the Office of Management and Budget.

Virginia Population Estimates: Growing More Slowly

28 January 2014

Every year, the Cooper Center produces the official population estimates for the commonwealth of Virginia. The estimates are based on changes since the 2010 census in housing stock, school enrollment, births, deaths, and drivers’ licenses. The estimates are used by state and local government agencies in revenue sharing, funding allocations, planning and budgeting.

Slower Growth Overall
This year’s estimates show that Virginia’s population grew by less than 1 percent between July 2012 and July 2013 to 8,260,405, the slowest growth since before the recession began. Between 2010 and 2013, Virginia’s population has grown 3.2 percent. While the number of births has fallen in recent years, the recent decline in Virginia’s growth rate was caused largely by fewer people moving into the state.
