There are only two cities that have had the distinction of being named the most populous city in the United States.

The first city to hold the title was Philadelphia, as the City of Brotherly Love was estimated to be the biggest city in the country at the time of the signing of the Declaration of Independence.

However, by the time of the first U.S. Census in 1790, New York City had surpassed Philadelphia by a few thousand residents – and the Big Apple has stayed the largest in the country ever since.

From Then to Now

Today’s infographic comes to us from Liberty Cruise, and it ranks the 10 most populous cities in the United States for every decade since 1790.

To start, let’s take a look at what the list looked just after the first U.S. Census in 1790:

RankCityPopulation (1790)
#1New York City, NY33,131
#2Philadelphia, PA28,522
#3Boston, MA18,320
#4Charleston, SC16,359
#5Baltimore, MD13,503
#6Northern Liberties Township, PA9,913
#7Salem, MA7,921
#8Newport, RI6,716
#9Providence, RI6,380
#10Marblehead, MA5,661

It’s pretty surreal to think that some of the biggest cities in the late 18th century hosted no more than 6,000 residents.

It also may be a surprise to many that Rhode Island – a state that ranks 50th in size and 44th in population today – held two of the largest towns in the nation at the time: Newport and Providence.

The Modern List

Jump forward over 200 years, and New York City has not lost its top spot.

It helped that NYC was able to absorb Brooklyn – one of the country’s other largest cities – into its boundaries in 1898. Other major cities saw similar merges happen over the years, with Philadelphia absorbing Northern Liberties Township, for example.

Here is a list of the most populous U.S. cities in 2017 (est.):

RankCityPopulation (Est. 2017)Population (2010 Census)Change
#1New York City, NY8,622,6988,175,133+5.47%
#2Los Angeles, CA3,999,7593,792,621+5.46%
#3Chicago, IL2,716,4502,695,598+0.77%
#4Houston, TX2,312,7172,100,263+10.12%
#5Phoenix, AZ1,626,0781,445,632+12.48%
#6Philadelphia, PA1,580,8631,526,006+3.59%
#7San Antonio, TX1,511,9461,327,407+13.90%
#8San Diego, CA1,419,5161,307,402+8.58%
#9Dallas TX1,341,0751,197,816+11.96%
#10San Jose, CA1,035,317945,942+9.45%

In contrast to the NYC of today, the 1790 population looks more like a Long Island suburb.

This rapid urbanization is mainly thanks to Industrial Revolution, which triggered a massive migration to cities, allowing New York to grow 26,000% in total population.

Here’s how the population distribution of New York City’s five boroughs has changed over time:

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

Rural counties across the U.S. are losing residents as large cities and the coasts are growing. This map shows U.S. population change by county.

Published

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.

#19South DakotaLincoln County44,82858,80731%
#2VirginiaLoudoun County312,311406,85030%

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.

Invisible Stars: Mapping America’s Rural Light Pollution

This unique map subtracts population from nighttime light output, giving us a unique perspective into America’s rural light pollution hot spots.

Invisible Stars: Mapping America’s Rural Light Pollution

From the bright lights of Times Square to the high-powered flood lights of a suburban Walmart, we expect our cities to give off a certain amount of light pollution. Even though our view of the universe is largely blotted out around city centers, there’s a measure of comfort in knowing an inspiring view of a starry night is only a short drive away.

Increasingly though, economic activity in America’s rural spaces is casting a glow into the sky, and now four out of five people in North America cannot see the Milky Way at night.

Today’s map, from geographer and journalist, Tim Wallace, is a different perspective on light pollution in the United States. The map was created by subtracting population from light output, which highlights areas that throw off more light than predicted given their population density.

On this style of map, it isn’t the glowing metropolitan centers of New York and Los Angeles that stand out, but regions like the oil-rich corner of South Dakota or the final leg of the Mississippi River. Let’s zoom in and investigate what’s happening in these unexpected illumination zones.

Oil & Gas

Some of the most prominent patterns on the map appear in regions where shale oil is being extracted.

In a relatively short amount of time, America became the largest oil producer on the planet. One of the major factors that fueled record production for shale oil producers was the proliferation of multi-well pad drilling — when multiple wells are drilled from a single drill site. From the air, it’s easy to spot these well formations spreading across the landscape, but the effect is even more pronounced at night.

At times, oil production is so strong that drillers flare the excess natural gas. In North Dakota alone, there are nearly 14,000 producing wells, and the resulting flares are what create the distinctive grid patterns on the map.

One of the brightest areas per capita in the country is Loving County, Texas. The county has around 100 residents, but more than 6,000 drilled wells.

Industrial Activities

Another point of interest on the map is Louisiana’s “petrochemical corridor”, running between New Orleans and Baton Rouge. An overhead view of Southern Louisiana in the daytime will be punctuated by the “ribbon farms” flanking the Mississippi River — a nod to the region’s history of French settlement.

At night though, a different scene emerges. Over 100 sprawling petrochemical facilities run by companies like Dow Chemical and Union Carbide dot the landscape, a patchwork of highly-illuminated plots.

Commercial Sprawl

Some types of infrastructure are typically located away from the city center. Airports, power stations, and racetracks, for example, need a lot of space and aren’t the most popular neighbors.

Another type of facility has been replacing farmland in recent years — logistics hubs. Many of the bright spots on the map outside cities show the warehouses and sortation centers that feed our growing demand for e-commerce.

economic logistics sprawl

In the example above, companies like Amazon, Home Depot, Dollar Tree, and Ikea have all clustered their facilities in the sparsely populated farmland south of Joliet, Illinois. This trend is repeated around the country, resulting in the “halos” of light that ring most cities on the map.

Flipping the Switch on Light Pollution

Though light isn’t toxic or overtly damaging to the natural landscape, it can still have a serious impact on wildlife, as well as blunting the beauty of the night sky.

The good news is that light is one of the easiest forms of pollution to prevent. New technologies and lighting techniques aren’t just good for our night skies, they’re generally more energy efficient as well.

Just as economic incentive lured buildings and infrastructure to America’s natural spaces, it may be energy efficiency that helps us return more of the night sky to its natural state.
