If you grew up in one of Northern Virginia’s suburban counties, such as Prince William, or in any of Virginia’s metro areas, you likely grew up with the impression that growth is as certain as the seasons. For decades, many counties in Virginia have grown relentlessly, constructing thousands of homes each year to house new […]

There is a lot of buzz amongst urbanists and demographers about the increasing gravitation of young adults towards 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 […]

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 […]

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 […]

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 […]

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 […]

When it comes to interactive data visualizations, I am a junky. I don’t mean the dime-a-dozen country maps showing the favorite baby name/band/movie/current fad for each state. I mean the kind that present information in a way that surprises me, even when I am relatively familiar with the data […]

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 […]

Last week, the Bureau of Labor Statistics released results from the 2013 American Time Use Survey. This survey, administered every year for the last decade, asks respondents–selected from people who have recently completed the Current Population Survey–to keep a diary of how they spent their time for a full 24 hour period. These data allow us to understand something about […]

No it’s not a party line.  It’s an almost perfectly straight line running north-south along 16th Street, passing through the White House, and then continuing along the Potomac River to the south.  It divides two very different sides of the DC area.These graphs are a cross-section of the DC area that looks at how the […]
