Animated Map: The History of U.S. Counties
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.
County Equivalents
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 |
---|---|
1790 | 292 |
1850 | 1621 |
1870 | 2247 |
1900 | 2713 |
1920 | 3041 |
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.
Short-lived Counties
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.
Continual Change
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.

Nearly 60% of the world’s 8 billion population lives in Asia: a vast continent sprawling over 44 million km², home to sprawling megacities, high-altitude deserts, the world’s biggest plateau, and impenetrable rainforests.
We visualize Asia’s population patterns using data from WorldPop—a research group based out of the University of Southampton that tracks population growth and movement across the globe.
A spike on the map denotes higher population density.

Ranked: Asia’s Countries By Population
Immediately the map visualizes at impressive scale a rather well-known fact: that India and China together account for 35% of the world’s population just by themselves.
Pakistan (ranked 4th in population) and Bangladesh (ranked 5th) together account for another 400 million people.
The role of the Himalayas in this distribution is understated: the mountain range is a source of ten major rivers, flowing to India, Nepal, Bangladesh, Pakistan, and China, providing fresh water to 1.3 billion people in its watershed.

Note: Russia and Georgia are typically regarded as European countries for cultural reasons, despite their geographic locations. They have been included in the dataset for context only.
Other countries that are covered by red: Indonesia (ranked 4th in population), Japan (ranked 7th), and the Philippines (8th), are all some of Asia’s most populous countries.
They also have some of the world’s densest cities:
- Manila: 42,857 people/km²
- Mumbai: 28,195 people/km²
- Karachi: 24,000 people/km²
- Jakarta: 14,464 people/km²
Tokyo and Beijing—despite being some of the world’s largest cities by population—record lower densities in comparison, helped by their much larger administrative areas.
But when sorted by average population density across the entire country, the ranks look a little bit different.
Ranked: Asia’s Countries By Population Density
The city state of Singapore is the densest country in Asia, with more than 8,000 people/km². Far behind it, the similarly sized in area Bahrain has one-sixth the population and ranks second (1,892/km²) in Asia’s densest countries.

Note: Russia and Georgia are typically regarded as European countries for cultural reasons, despite their geographic locations. They have been included in the dataset for context only.
Bangladesh, with 1,180 people/km², has the rare distinction of being a top five Asian country by both population and average population density.
Meanwhile, India is 9th in population density (437 people/km²), its large landmass bringing down the average considerably.
Similarly, China nearly breaks into the top 20 with a population density of 149 people/km². Despite its vast population, the country’s immense size presents a challenge, particularly in its western regions, which are largely inhospitable to substantial human settlement due to the presence of mountains, the Tibetan plateau, and two deserts.
At the bottom of the rankings, Mongolia (2 people/km²) and Kazakhstan (7 people/km²) are some of the least dense countries in the world.
