Growth and Decline: Visualizing U.S. Population Change by County

Visualizing U.S. Population Change by County (2010-2018)

The American Heartland continues to feed the growth of urban centers — not only with its agricultural products and natural resources, but with its people as well.

Across the nation, coastal urban centers are adding new citizens, while rural counties are seeing their populations decline. Outside of this general trend, fracking has created some rare pockets of growth in rural areas, while coal mine closures have had the opposite effect.

Today’s map comes to us from Reddit user jinkinson, and it maps U.S. population change by county from 2010 to 2018, using data from the U.S. Census Bureau.

Uneven Growth

From 2010 to 2018, the total United States population increased by 6% from 308,745,538 to 327,167,434. However, it’s clear that not all counties participated in this uptrend.

There are 3,142 counties counted as part of this map (Puerto Rico and U.S. territories excluded). Of these, 1,489 experienced positive growth, while 1,653 saw a decline.

Which Counties are Growing the Fastest?

America’s economy has grown for over a decade, but that growth increasingly concentrates in 1% of the nation’s counties.

In fact, just 31 counties were responsible for 32.3% of the U.S. gross domestic product (GDP) in 2018, according to data from the Bureau of Economic Analysis.

Although economic concentration tells part of the story, a view of changing population patterns can help us see where physical growth is happening across the country.

At the top of the list is McKenzie County, North Dakota, which experienced a growth of 114% in its population from 2010 to 2018. This is due to the shale gas industry that flourished in the area. Interestingly, all of North Dakota’s active oil and gas rigs are in just four counties: McKenzie, Dunn, Williams, and Mountrail, three of which make the top 20 list above.

The fracking boom also fueled growth in Texas, where six counties made the list.

However, immediate economic success built on fracking sands and sensitive commodity prices may not be sustainable over the longer term. In fact, counties from a previous energy era are already seeing what happens when demand dries up.

Which Counties are Declining the Fastest?

If you look at a map of coal operations in the U.S. and compare it to the list of declining counties below, a stark pattern appears.

Half of country’s coal miners work in just 25 counties, and as mines close there are fewer economic opportunities available in those areas.

While coal counties have grim figures due to the changing domestic energy story, it’s Alexander County in Illinois that tops the list with a 26% decline in population over the time period.

In fact, the harsh reality is that 93% of Illinois’ counties have seen a decrease in population between 2010-2018.

Illinois tops the list with the most people leaving its counties, while areas such as the District of Columbia and Delaware experienced no declines.

What happens to a state where the majority of its counties are losing residents?

The Big Picture

Americans are seeking out opportunity where it resides: in the cities. The pursuit of fracking oil and gas created opportunities in regions beyond the coast or traditional urban centers.

However, the long term trend of concentration of people on coasts and in major urban centers will continue to impact infrastructure spending, labor mobility, and economic activity. America no longer derives the majority of its economic success from rural counties and industries.

It is unclear how rural counties will fare as their denizens continue to dwindle. What is clear is that the few that rely on natural resources for success will continue to experience the ups and downs of volatile commodity markets.

Ranked: The 10 Most Expensive Cities in the World

From Osaka to New York, we look at a global ranking of the 10 most expensive cities, and how those rankings have changed over the last year.

Published

The Most Expensive Cities in the World

Where personal wealth is concerned, there are two sides to every story.

The first of which is the amount of money a person earns, and the other is what they choose to spend their money on. The latter is influenced by the cost of living in the city where they reside—an ever-changing metric that is driven by a wide variety of factors, such as currency, population growth, or external market movements.

Today’s graphic visualizes the findings from the 2020 Worldwide Cost of Living report and uses data from 133 cities to rank the most expensive cities in the world.

Note: Report research was conducted towards the end of 2019, before the COVID-19 outbreak.

Asia Dominates the Ranking

Globally, the cost of living has fallen by an average of 4% over the last year, with much of the movement up and down the ranking being driven by currency fluctuations.

The locations with the highest cost of living are largely split between Europe and Asia. For the second time in the report’s 30-year history, three cities are tied as the top spot—Singapore, Hong Kong, and Osaka.

Source: EIU. New York City is index baseline (score = 100). Ties in index score values are denoted by (t).

Osaka is a newcomer to the top spot, climbing four places over the last year to join cost of living heavyweight champions, Singapore and Hong Kong. As Japan’s third-largest city, Osaka is a major financial hub and a breeding ground for emerging startups, with relatively low real estate costs compared to Singapore and Hong Kong.

Three European cities (Paris, Zurich, and Geneva) sit atop the most expensive city rankings, compared to seven cities only 10 years ago. Similarly, 31 of the 37 European cities have seen a decrease in cost of living overall—largely as a result of the Euro or local currencies losing value relative to the U.S. dollar.

Finally, the top 10 is rounded out with two cities from the United States (New York, Los Angeles) and one from Israel (Tel Aviv).

The Cheapest Cities

While East Asia is home to many of the world’s most expensive cities, South Asia hosts the largest grouping of cities with the lowest cost of living.

#125🇮🇳 IndiaBangalore404
#122(t)🇮🇳 IndiaNew Delhi421

Source: EIU. New York City is index baseline (score = 100). Ties in index score values are denoted by (t).

Three Indian cities dominate the cheapest cities ranking due to a combination of low wages and high levels of income inequality, preventing any price increases.

Meanwhile, political and economic turmoil is a common denominator among the cheapest cities outside of South Asia. For example, the Syrian Civil War resulted in an economic collapse, leading to high inflation and a downward spiral in value for the Syrian pound.

A Spanner in the Works

The COVID-19 pandemic is estimated to cost the global economy up to $2 trillion in 2020, so while governments attempt to boost the economy, many are concerned about higher inflation rates spreading across the world.

With a recession becoming more likely, uncertainty around real estate prices will heighten for every city, regardless of their cost of living ranking.

As we navigate chaotic and uncertain times, the next cost of living survey could look very different to today—the most important question will be how permanent the damaging effects of the pandemic will be.

Visualizing the Footprint of Highways in American Cities

Highways improved mobility for the average American, ingraining the automobile into the urban fabric of American cities, for better and worse.

The Impact of Highways

Footprint of Highways in American Cities

Visualizing the Footprint of Highways in American Cities

Driving on the open road is a defining feature of the American experience, made possible by coast-to-coast highways. It defined a generation of life and ingrained the automobile into the urban fabric of American cities, for better and worse.

Today’s animations show how highways reshaped the downtown cores of six American cities and created new patterns of urban life. But first, some background information on the creation of the interstate system.

The Interstate Highway System

The U.S. Interstate System was created on June 29, 1956, when Dwight Eisenhower signed the Federal-Aid Highway Act. It would eventually run 46,876 miles, cost $521 billion and take 36 years to complete.

Map of the US Interstate System

From San Diego to Bangor, the interstate highway system connected Americans and opened up the country to commerce and geographic mobility like never before, but for all its benefits, this new transportation network ripped through established patterns of urban and town life, creating a new era of urban development.

The Legacy of Highways: The Suburbs and Inner Cities

The vast geography of continental America helped to entrench personal mobility and freedom into American society. Highways and automobiles accelerated this lifestyle and even changed the shape of entire cities.

According to Prof. Nathaniel Baum-Snow of the University of Toronto, between 1950 and 1990, the population of central cities in the U.S. declined by 17% despite a population growth of 72% in larger metropolitan areas during the same period. Baum-Snow posits that, had the interstate highway system not been built, central cities’ populations would have increased 8%.

Firms followed the workers to the suburbs, but the highways system also created additional benefits for these firms. Cross-country road access freed manufacturing from ports and downtown rail hubs, while allowing economies to operate across larger distances, altering the dynamics of typical urban economies.

Faced with this new reality, inner cities struggled in years to come.

Inner Cities

The introduction of highways created an increase in the supply of land for development through faster commutes to outlying areas. In 1950, half of all jobs were located in central cities. By 1990, less than one-third of urban jobs were located in the core of American cities.

“Not TV or illegal drugs but the automobile has been the chief destroyer of American communities.” Jane Jacobs, Author The Death and Life of Great American Cities

Benefits of new development accrued to the outer areas while the construction of the highways in inner cities displaced largely low-income communities, segregated neighborhoods, increased the amount of air and noise pollution, devalued surrounding properties, and removed access to jobs for those without a car, further concentrating poverty.

Before and After: Six American Cities

A bird’s eye view of six American cities reveals what was and what is now. By overlaying existing highways over the neighborhoods they replaced, it becomes clear how much interstate construction drastically altered America’s urban landscape.

Oakland
Public opposition to the construction of I-980 was so strong that developers abandoned the project in 1971, only to complete it over a decade later.

Miami Highway
The I-95 carved through Miami’s largely black Overtown neighborhood. The construction of a single highway cloverleaf resulted in 20 square blocks being demolished, displacing over 10,000 people in that community.

Providence Highway
The I-95 comprised unconnected segments between 1957 and 1965 through the densest urban areas in a deliberate effort to prevent premature suburbanization and to revitalize the downtown core.

Cincinnati Highway
The I-71 cuts downtown Cincinnati off from its waterfront and a massive freeway interchange forced the destruction of dozens of blocks west of downtown.

Detroit highway construction
Freeway construction transformed Detroit between 1951 and 2010. Previously, its downtown had been surrounded by a high-density street grid. Today, it’s totally encircled by freeways.

Rochester Highway
Rochester is one of many cities opting to undertake freeway removal projects.

As the dotted line above shows, the “moat” surrounding downtown is slowly being removed. The city used reclaimed land from the Inner Loop freeway to construct three mixed-use developments that include below-market-rate units.

The Future of Urban Living: Do Highways Matter?

A new era of living is reconsidering the impacts of these highways on urban centers. As property values rise and existing housing stock is pressured, there are growing concerns over the environmental impacts of suburban life. As a result, urban planners and residents are looking to revitalize city cores and re-purpose land occupied by burdensome slabs of highway concrete.

Since 1987, there have been more than 20 urban highway segments removed from downtown cores, neighborhoods and waterfronts, mostly in North America. The pace of removals has picked up significantly and an additional 10 highways are now planned for removal in the United States.

During the COVID-19 pandemic, American cities have seen their traffic plummet. Rush-hour trips into cities are taking nearly half the time while some are not even commuting at all.

While this situation is likely temporary, it is offering a moment for reflection of how cities operate and whether the car should be at the center of urban planning.
