The Best Map Ever Made Of America’s Racial Segregation

October 17, 2014

Last year, a pair of researchers from Duke University published a report with a bold title: “The End of the Segregated Century.” U.S. cities, the authors concluded, were less segregated in 2012 than they had been at any point since 1910. But less segregated does not necessarily mean integrated–something this incredible map makes clear in vivd color.

The map, created by Dustin Cable at University of Virginia’s Weldon Cooper Center for Public Service, is stunningly comprehensive. Drawing on data from the 2010 U.S. Census, it shows one dot per person, color-coded by race. That’s 308,745,538 dots in all–around 7 GB of visual data. It isn’t the first map to show the country’s ethnic distribution, nor is it the first to show every single citizen, but it is the first to do both, making it the most comprehensive map of race in America ever created.

White people are shown with blue dots; African-Americans with green; Asians with red; and Latinos with orange, with all other race categories from the Census represented by brown. Since the dots are smaller than pixels at most zoom levels, Cable assigned shades of color based on the multiple dots therein. From a distance, for example, certain neighborhoods will look purple, but zooming-in reveals a finer-grained breakdown of red and blue–or, really, black and white.

“There are a lot of moving parts in this process, so this can cause different shades of color to appear at different zoom levels in really dense areas, like you see in NYC,” Cable explains. “I played around with dot size and transparency for a while and settled on the current scheme as being adequate.” You can read more about Cable’s methodology here, but it comes down to this: When you’re dealing with 300 million dots at varying levels of zoom, getting the presentation just right is as much an art as a science.

Looking at the map, every city tells a different story. In California, for example, major cities aren’t just diverse, they’re integrated to a great degree, too. We see large swaths of Sacramento dotted variously with reds, blues, oranges, greens and browns. Los Angeles is more distinctly clustered, but groups still bleed into one another.

In the Midwest, though, the racial divide can be shockingly exact. In Chicago, bands of whites, blacks, and Latinos radiate out from the city center like sun beams. In St. Louis, a buffer of a few blocks separates a vast area of largely black citizens from another of white and Asian ones. In Detroit, the most segregated city in America according to one recent study, there’s no buffer at all. We see how 8 Mile Road serves as the dividing line between two largely homogenous swaths–one predominantly white and one predominantly black.

Looking at the Southeast, a wide, faint band of green represents the Black Belt, a region originally named for the dark soil in Alabama and Mississippi that eventually came to describe the greater region shaped by plantation agriculture. And while the West looks awfully barren, the density of cities like Los Angeles, Dallas, and Houston gives us a sense of why those states are actually so populous.

Responding to the Duke University study last year, experts were quick to expound on the complexities of the issue. Housing desegregation, one pointed out, is not a magic bullet for equal opportunity. Another made clear that blacks remained more segregated from whites than Latinos or Asians. Here, at least, Cable’s given us a chance to see how things stand today in greater detail than ever before.

Where We Went, State By State

Last August, the New York Times released a set of interactive charts illustrating domestic migration by state since 1900. This series came to mind while we were thinking about talent retention and attraction. This tool, based on data from the US Census, charts state of birth versus state of residence of the US population for more than 100 years. Alternatively, you can view where people living in a state came from.

Understanding the migration patterns of a community can provide a framework for the design of a talent management strategy. Though state-level data does not lead directly to a detailed approach, it can help illustrate a state’s top talent “trading partners” and serve as a preliminary tool for recruitment. The flow of residents can also reveal patterns of economic change.

For example, comparing TIP Strategies’ two home states, Washington and Texas, reveal different dynamics of growth in each state. In recent decades, Texas has dramatically increased its non-native population, while simultaneously retaining 82% of its native population. Those who leave the Lone Star state are often drawn to other parts of the West and South. This is a change from decades earlier when Oklahoma was the primary target of Texas’s out-migration.

By contrast, Washington, like all western states, has attracted migrants for over 100 years. It retains a high percentage of natives–70 percent–but more than 50 percent of its population in 2012 was born elsewhere. Washington’s deep connection to the West Coast can be seen in the view of its diaspora which reveals that the vast majority of those who do leave the state remain in the West, a pattern which has held for more than 100 years.


Story Maps Illustrate Metro Area And County Population Change

The Census Bureau [recently] released two interactive thematic maps on population change.
These ‘Story Maps’ provide insight on emerging trends in population change across the country,” said Jason Devine of the Census Bureau’s Population Division.

The first map allows data users to explore the difference a decade has made in patterns of population change in metropolitan and micropolitan statistical areas across the country. This is possible through swiping between two interactive maps – one covering the 2002-2003 period, the other 2012-2013.

The second map permits users to determine the extent of population growth in each county between 2012 and 2013, and to quickly identify the primary source of that population change (such as natural increase or net migration).

Restless America: State-to-State Migration In 2012

Migration flows in the United States

Click here for interactive map.
Approximately 7.1 million Americans moved to another state in 2012. That’s over 2.2% of the U.S. population. The United States has a long history of people picking up and moving their families to other parts of the country, in search of better livelihoods. That same spirit of mobility, a willingness to uproot oneself, seems alive and well today based on the visualization of migration patterns above.
The visualization is a circle cut up into arcs, the light-colored pieces along the edge of the circle, each one representing a state. The arcs are connected to each other by links, and each link represents the flow of people between two states. States with longer arcs exchange people with more states (California and New York, for example, have larger arcs). Links are thicker when there are relatively more people moving between two states. The color of each link is determined by the state that contributes the most migrants, so for example, the link between California and Texas is blue rather than orange, because California sent over 62,000 people to Texas, while Texas only sent about 43,000 people to California. Note that, to keep the graphic clean, I only drew a link between two states if they exchanged at least 10,000 people.
I saw a few interesting things in this graphic:
• First, there are more people leaving California than there are arriving there. 566,986 people left the Golden State in 2012, for states like Texas, Nevada, Washington, and Arizona, presumably for the lower cost of living.
• New York also shows more people leaving than arriving. The most popular destination for New Yorkers is Florida. My hunch is that these are retirees. The next most popular destinations are New Jersey and Pennsylvania. More likely these folks are leaving pricey New York City for more affordable suburbs in neighboring states.
• Migrants are flocking to Florida. Interestingly the state contributing the most migrants to Florida is neighboring Georgia. Texas, New York, and North Carolina are the next largest contributors.
• Texas is the second-largest destination for migrants. Over 500,000 people moved to Texas in 2012. People tend to come from the Southeast, Southwest, and the West, with the biggest contributor being California. 62,702 Californians packed up and moved to the Lone Star state in 2012.
• Most people leaving DC tend to stay in the area, opting for Virginia or Maryland. The economy of DC, centered around the federal government, seems to discourage more distant migrations.
• The migrants who leave two very cold states, Maine and Alaska, have very clear preferences. Their most popular destinations are Florida and California.

Office And Administrative Support Occupations Make Up Nearly 16 Percent Of U.S. Employment, May 2013

In May 2013, office and administrative support was the largest occupational group, making up nearly 16 percent of total U.S. employment. The next largest groups were sales and related occupations and food preparation and serving related occupations, which made up about 11 and 9 percent, respectively. Seven of the 10 largest occupations were in one of these three groups.

The smallest occupational groups included legal occupations and life, physical, and social science occupations, each making up less than 1 percent of total employment in May 2013.
The highest-paying occupational groups were management, legal, computer and mathematical, and architecture and engineering occupations. Most detailed occupations in these groups were also high paying. For example, all 19 computer and mathematical occupations had average wages above the U.S. all-occupations mean of $46,440, ranging from $50,450 for computer user support specialists to $109,260 for computer and information research scientists.
The lowest-paying occupational groups were food preparation and serving related; farming, fishing, and forestry; personal care and service; building and grounds cleaning and maintenance; and healthcare support occupations. Annual mean wages for these groups ranged from $21,580 for food preparation and serving related occupations to $28,300 for healthcare support occupations. With few exceptions, the detailed occupations in these groups had below-average wages. For example, occupational therapy assistants and physical therapy assistants were the only healthcare support occupations with mean wages above the U.S. all-occupations mean.
Among 665,850 employed persons in the District of Columbia in May 2013, there were about 3,370 political scientists—accounting for 50.6 out of every 10,000 jobs in the District of Columbia. In all of the United States there were 5,570 political scientists employed out of a total of 132,588,810 employed people—meaning less than 1 (0.42) out of every 10,000 jobs in America were political scientists. The ratio that compares the concentration of employment in a defined area (in this case, the District of Columbia) to that of a larger area (the United States) is referred to by the Bureau of Labor Statistics as the “location quotient.”

Click here for interactive version
The location quotient of political scientists in the District of Columbia is 50.6 divided by 0.42 (the location quotient of political scientists in the United States), which equals about 120.5—indicating there are about 120.5 times as many political scientists per 10,000 total employed people in the District of Columbia as in the United States as a whole.

Practitioners’ Forum: What Does the Future of Jobs Mean for Your Community?

January 30, 2012

Over the past two months, we have been engaged in a conversation about the future of jobs with economic development practitioners at the TEDC and IEDC conferences.
Now, we’d like to create an open forum to continue this dialogue beyond the conference setting. In the comments section of this post, you’re invited to respond to the following questions, or pose additional questions for your peers.
How will the “future of jobs” change how you approach economic development?
What mechanisms have you created to support corporations and freelance workers in your community?

Below you’ll find a video of Jon’s recent IGNITE presentation from IEDC’s Leadership Summit in San Antonio. The IGNITE structure allows speakers 5 minutes total to present in the form of 20 slides, with 15 seconds per slide. A brief overview of the presentation follows the slide show.

The Future of Jobs from GIS Planning on Vimeo.

This is a discussion about the future of jobs. The idea of what a job is has changed throughout history (and continues to change). Farmers and craftsmen have always had trades, or livelihoods. Since the industrial revolution, a fundamental shift in the nature of jobs has occurred; individuals are employed by entities (corporations) and in return for their labor (9-5), they are compensated (wages) and receive benefits (healthcare, etc.). When unemployment is high, as it has been in the aftermath of the recent recession, we must ask ourselves who should create jobs: the public sector? the private sector? Can the economy continue to grow, even if jobs are not being created? (answer: yes).
The economy grows when value is created. Corporations can create value by increasing productivity (but not necessarily increasing employment), and independent contractors can create value outside of a traditional employee-employer relationship. If we take this thought experiment to its logical extreme, could there be corporations without people on the horizon? Will trade guilds become an organizing structure for independent contractors in a variety of professions?
If jobs are no longer the most useful or accurate measure of economic development success, how can practitioners best promote economic vitality in their communities? Are there mechanisms by which cities, regions, and states can offer resources to corporations and freelancers that will support their ability to create value, regardless of hiring trends or employment status?
We invite you to participate in this conversation in the comments section below.
