Animated Video: The History of U.S Counties
Did you know that there are 3,142 different counties in the U.S. today?
Going as far back as the 1600s, English settlers arriving in the New World envisioned counties as a means of accessible government—a county seat was meant to be within a day’s buggy ride for every citizen.
While the role of counties in local government has remained significant in modern times, their boundaries have changed drastically over the years.
This animated map by Alexander Varlamov visualizes the history of U.S. county borders, and how these jurisdictions have evolved over time.
Before diving in, it’s important to note a few county-equivalents that function similarly but go by different names:
- Boroughs/Census areas: Alaska is made up of 19 boroughs, but the majority of its landmass is not included in them. Rather, it’s officially labeled by the Alaskan government as the unorganized borough.
- Parishes: Instead of counties, Louisiana uses the term parishes because of its French and Catholic heritage.
- Independent cities: These are cities that operate outside their surrounding county’s jurisdiction. There are 41 independent cities in the U.S. and 38 of them are in Virginia.
Over 300 Years of Growth
The number of counties in the U.S. has increased dramatically since the early days of American history. Here’s a look at their growth since 1790:
|Year||Number of Counties and Parishes|
The first county was established in 1634, over 100 years before the first Census was taken (and long before America gained independence). It was created in James City, Virginia—an interesting location, considering Virginia now has the highest concentration of independent cities.
Why does Virginia have so many independent cities? The state’s separation of counties and cities dates back to the early 1700s. With a rural population and low productivity, it was difficult to establish town centers. After several attempts, the General Assembly gave up. Independent cities were established instead.
Counties as a political organization have been around for hundreds of years, but some individual counties haven’t lasted long.
For instance, Bullfrog County in Nevada was established in 1987 and dissolved just two years later. During its brief existence, it had no population and no infrastructure—and its primary purpose was simply to prevent Yucca Mountain from becoming a nuclear waste dump.
While Bullfrog County has since been dissolved, the controversy around the nuclear waste site is ongoing as of 2020.
The latest official county, Broomfield Country, was established in Colorado in 2001.
Although it’s been decades since the last county was created, there have been continual boundary changes and status updates—sometimes for political reasons. For instance, the Supreme Court recently ruled that half of Oklahoma is within a Native American reservation. While this doesn’t necessarily change ownership, it does affect jurisdiction and county authority.
Though the lines on the map are more or less static now, the invisible lines of county jurisdiction will continue to change and evolve over time.

We visualize how far popular EV models will take you on real-world routes between major cities, and which are the most cost effective.
The Range of EVs on Major Highway Routes
Between growing concerns around climate change, new commuting behaviors due to COVID-19, and imminent policy changes, the global transition to electric vehicles (EVs) is well under way.
By the year 2040, sales of electric vehicles are projected to account for 58% of new car sales, up from just 2.7% currently.
But switching from a gasoline car to an electric one is not seamless. With charging and range capacities to consider, and the supporting infrastructure still being slowly rolled out in many parts of the world, understanding the realities of EV transportation is vital.
Above, we highlight 2020 all-electric vehicle range on well-recognized routes, from California’s I-5 in the U.S. to the A2 autobahn in Germany. The data on estimated ranges and costs are drawn from the U.S. EPA as well as directly from manufacturer websites.
The EV Breakdown: Tesla is King of Range
For many consumers, the most important aspect of an electric vehicle is how far they can travel on a single charge.
Whether it’s for long commutes or out-of-city trips, vehicles must meet a minimum threshold to be considered practical for many households. As the table below shows, Tesla’s well-known EVs are far-and-away the best option for long range drivers.
|Vehicle||Range (miles)||Range (km)||MSRP||Cost per mile|
|Tesla Model S Long Range Plus||402||647||$74,990||$186.54|
|Tesla Model X Long Range Plus||351||565||$79,990||$227.89|
|Tesla Model S Performance||348||560||$94,990||$272.96|
|Tesla Model 3 Long Range||322||518||$46,990||$145.93|
|Tesla Model Y Long Range||316||509||$49,990||$158.20|
|Tesla Model X Performance||305||491||$99,990||$327.84|
|Tesla Model 3 LR Performance||299||481||$54,990||$183.91|
|Tesla Model Y Performance||291||468||$59,990||$206.15|
|Chevrolet Bolt EV||259||417||$36,620||$141.39|
|Hyundai Kona Electric||258||415||$37,190||$144.15|
|Tesla Model 3 Standard Range Plus||250||402||$37,990||$151.96|
|Kia Niro EV||239||385||$39,090||$163.56|
|Nissan LEAF e+ S||226||364||$38,200||$169.03|
|Audi e-tron Sportback||218||351||$69,100||$316.97|
|Nissan LEAF e+ SV/SL||215||346||$39,750||$184.88|
|Porsche Taycan 4S Perf Battery Plus||203||327||$112,990||$556.60|
|Porsche Taycan Turbo||201||323||$153,510||$763.73|
|Porsche Taycan Turbo S||192||309||$187,610||$977.14|
|Hyundai IONIQ Electric||170||274||$33,045||$194.38|
|MINI Cooper SE||110||177||$29,900||$271.82|
In an industry where innovation and efficiency are vital, Tesla’s first-mover advantage is evident. From the more affordable Model 3 to the more luxurious Model S, the top eight EVs with the longest ranges are all Tesla vehicles.
At 402 miles (647 km), the range of the number one vehicle (the Tesla Model S Long Range Plus) got 127 miles more per charge than the top non-Tesla vehicle, the Polestar 2—an EV made by Volvo’s standalone performance brand.
Closer Competition in Cost
Though Tesla leads on overall range and battery capacity, accounting for the price of each vehicle shows that cost-efficiency is far more competitive among brands.
By dividing the retail price by the maximum range of each vehicle, we can paint a clearer picture of efficiency. Leading the pack is the Chevrolet Bolt, which had a cost of $141.39/mile of range in 2020 while still placing in the top 10 for range with 259 miles (417 km).
Just behind in second place was the Hyundai Kona electric at $144.15/mile of range, followed by the Tesla Model 3—the most efficient of the automaker’s current lineup. Rounding out the top 10 are the Nissan LEAF and Tesla Model S, but the difference from number one to number ten was minimal, at just over $45/mile.
|Top 10 All-Electric Vehicles by Cost Efficiency|
|Vehicle||Cost per mile|
|Chevrolet Bolt EV||$141.39|
|Hyundai Kona Electric||$144.15|
|Tesla Model 3 Long Range||$145.93|
|Tesla Model 3 Standard Range Plus||$151.96|
|Tesla Model Y Long Range||$158.20|
|Kia Niro EV||$163.56|
|Nissan LEAF e+ S||$169.03|
|Tesla Model 3 LR Performance||$183.91|
|Nissan LEAF e+ SV/SL||$184.88|
|Tesla Model S Long Range Plus||$186.54|
Higher Ranges and Lower Costs on the Horizon
The most important thing to consider, however, is that the EV industry is entering a critical stage.
On one hand, the push for electrification and innovation in EVs has driven battery capacity higher and costs significantly lower. As batteries account for the bulk of weight, cost, and performance in EVs, those dividends will pay out in longer ranges and greater efficiencies with newer models.
Equally important is the strengthening global push for electric vehicle adoption. In countries like Norway, EVs are already among the best selling cars on the market, while adoption rates in China and the U.S. are steadily climbing. This is also being impacted by policy decisions, such as California’s recent announcement that it would be banning the sale of gasoline cars by 2035.
Meanwhile, the only thing outpacing the growing network of Tesla superchargers is the company’s rising stock price. Not content to sit on the sidelines, competing automakers are rapidly trying to catch up. Nissan’s LEAF is just behind the Tesla Model 3 as the world’s second-best-selling EV, and Audi recently rolled out a supercharger network that can charge its cars from 0% to 80% at a faster rate than Tesla.
As the tidal wave of electric vehicle demand and adoption continues to pick up steam, consumers can expect increasing innovation to drive up ranges, decrease costs, and open up options.

3D Map: The U.S. Cities With the Highest Economic Output
The total U.S. GDP stands at a whopping $21 trillion, but which metro areas contribute to the most in terms of economic output?
3D Map: The U.S. Cities With the Highest Economic Output
At over $21 trillion, the U.S. holds the title of the world’s largest economy—accounting for almost a quarter of the global GDP total. However, the fact is that a few select cities are responsible for a large share of the country’s total economic output.
This unique 3D map from HowMuch puts into perspective the city corridors which contribute the most to the American economy at large.
Top 10 Metros by Economic Output
The visualization pulls the latest data from the U.S. Bureau of Economic Analysis (BEA, 2018), and ranks the top 10 metro area economies in the country.
One thing is immediately clear—the New York metro area dwarfs all other metro area by a large margin. This cluster, which includes Newark and Jersey City, is bigger than the metro areas surrounding Los Angeles and Chicago combined.
|Rank||Metro Area||State codes||GDP (2018)|
|#1||New York-Newark-Jersey City||NY-NJ-PA||$1.77T|
|#2||Los Angeles-Long Beach-Anaheim||CA||$1.05T|
|#7||Houston-The Woodlands-Sugar Land||TX||$0.48T|
Coming in fourth place is San Francisco on the West Coast, with $549 billion in total economic output each year. Meanwhile in the South, the Dallas metroplex brings in $478 billion, placing it sixth in the ranks.
It’s worth noting that using individual metro areas is one way to view things, but geographers also think of urban life in broader terms as well. Given the proximity of cities in the Northeast, places like Boston, NYC, and Washington, D.C. are sometimes grouped into a single megaregion. When viewed this way, the corridor is actually the world’s largest in economic terms.
U.S. States: Sum of Its Parts
Zooming out beyond just these massive cities demonstrates the combined might of the U.S. in another unique way. Tallying all the urban and rural areas, every state economy can be compared to the size of entire countries.
According to the American Enterprise Institute, the state of California brings in a GDP that rivals the United Kingdom in its entirety.
By this same measure, Texas competes with Canada in terms of pure economic output, despite a total land area that’s 15 times less that of the Great White North.
With COVID-19 continuing to impact parts of the global economy disproportionately, how will these kinds of economic comparisons hold up in the future?
