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:

YearNumber of Counties and Parishes
1790292
18501621
18702247
19002713
19203041

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.

Animated Map: What America Searched for on Google, Over the Last Decade

This fascinating animated map provides an overview of the top trending Google searches in every state over the last decade.

What America Searched for on Google, in the Last Decade

Cultural shifts come in many shapes and forms, and some are harder to measure than others.

Thankfully, Google search volume provides an easy avenue for measuring large-scale cultural trends. And because Google makes up more than 90% of all internet searches in the U.S., looking at what’s trending on Google is a great way to understand the shifting questions and interests that are captivating society at any given time.

This animated map by V1 Analytics provides an overview of the top trending Google searches in every state over the last decade. It sheds light on what types of new information, events, and stories received the most attention in the last ten years—and more generally, it shows us what the U.S. population has been thinking about.

Trending Searches versus Top Searches

Before diving into the top trends of the decade, it’s worth taking a moment to distinguish between “trending searches” and “top searches”:

  • Trending Searches: Keywords that had the largest increase in traffic, in a specific period of time
  • Top Searches: The most searched keywords in a given time frame

This video would look a lot different, and a lot less interesting, if it showed Google’s top searches. To give some perspective, here are the Top 10 Searches in the U.S. (as of 2020):

RankKeyword
#1facebook
#2youtube
#3amazon
#4gmail
#5google
#6weather
#7ebay
#8yahoo
#9walmart
#10yahoo mail

Understanding the difference between trending searches and top searches is important because it gives us insight into why certain keywords trend in some places, but not others. For instance, in March 2020, the word “coronavirus” was trending throughout a majority of the U.S., with a few exceptions—it wasn’t trending in Massachusetts, California, Texas, Nevada, or Arizona.

It’s easy to make the assumption that people in these states were not concerned about COVID-19—however, that’s not necessarily the case.

It’s important to remember that trending searches are measured by the increase of traffic, not just the overall amount of searches. Therefore, in states where it wasn’t trending, the word “coronavirus” may have already been a popular search term for a while, so the keyword didn’t see a sudden spike in interest like it did in other places.

Undivided Attention

In the last decade, there were moments when the entire country was googling the same thing. Some keyword trends lasted a day, while others lasted over a week.

Here’s a look at keywords that took over the whole U.S, and when they were trending unanimously:

It’s interesting to look at the variety of topics that dominate the population’s collective thoughts. There’s a unique mix of popular culture, entertainment, electronics, prominent figures, and public scandals.

Something else worth noting is how country-wide trends became a lot more common in the latter part of the decade—in 2019 for example, 9 keywords trended unanimously. This was more than in the entire first half of the decade.

While the secret to going viral remains a mystery, one thing remains clear—the public certainly has a broad range of interests. So really, it’s anyone’s game.

Mapped: Each Region’s Median Age Since 1950

The world’s population is aging, but not at the same rate. This animated map visualizes the changes in median age in every region since 1950.

Mapped: Each Region’s Median Age Since 1950

Over the last 70 years, the global population has gotten older. Since 1950, the worldwide median age has gone from 25 years to 33 years.

Yet, despite an overall increase globally, not all regions have aged at the same rate. For instance, Europe’s median age has grown by 14 years, while Africa’s has only increased by 1 year.

Today’s animated map uses data from the UN Population Index to highlight the changes in median age over the last 70 years, and to visualize the differences between each region. We also explain why some regions skew older than others.

Factors that Affect a Region’s Median Age

Before diving into the numbers, it’s important to understand the key factors that influence a region’s median age:

  1. Fertility Rate
    The average number of children that women give birth to in their reproductive years. The higher the fertility rate, the younger a population skews. Since 1950, the global fertility rate has dropped by 50%.
  2. Mortality Rate
    The number of deaths in a particular region, usually associated with a certain demographic or period in time. For example, global child mortality (children who have died under five years of age) has been on the decline, which has contributed to an increase in the average life expectancy across the globe.
  3. Migration
    International migration may lower a region’s population since migrants are usually younger or working age. In 2019, there were 272 million migrants globally.

The Change in Median Age

As mentioned, not all regions are created equal. Here’s how much the median age has changed in each region since 1950:

The Highs

Regions that have seen the most growth and generally skew older are Latin America, followed by Europe and Asia.

Interestingly, Asia’s notable increase is largely influenced by Japan, which has the oldest population on the planet. The country has seen a significant increase in median age since 1950—it’s gone from 22 to 48 years in 2020. This can be explained by its considerably low fertility rate, which is 1.4 births per woman—that’s less than half the global average.

But why is Japan’s fertility rate so low? There are more women in the workforce than ever before, and they are too busy to take on the burden of running a household. Yet, while women are more prosperous than ever, the workforce in general has taken a hit.

Japan’s recession in the early 1990s led to an increase in temporary jobs, which has had lasting effects on the region’s workforce—in 2019, about 1 in 5 men were working contract jobs with little stability or job growth.

The Lows

In contrast to Asia’s growth, Africa has seen the lowest increase in median age. The region’s population skews young, with over 60% of its population under the age of 25.

Africa’s young population can be explained by its high birth rate of 4.4 births per woman. It also has a relatively low life expectancy, at 65 years for women and 61 years for men. To put things into perspective, the average life expectancy across the globe is 75 years for women and 70 years for men.

Another trend worth noting is Oceania’s relatively small growth. It’s interesting because the region’s fertility rate is almost on par with the global average, at 2.4 births per woman, and the average life expectancy doesn’t differ much from the norm either.

The most likely reason for Oceania’s stagnant growth in median age is its high proportion of migrants. In 2019, the country had 8.9 million international migrants, which is 21% of its overall population. In contrast, migrants only make up 10% of North America’s population.

Unique Challenges for Every Region

Age composition has significant impacts on a region’s labor force, health services, and economic productivity.

Regions with a relatively high median age face several challenges such as shrinking workforce, higher taxes, and increasing healthcare costs. On the other end of the spectrum, regions with a younger population face increased demand for educational services and a lack of employment opportunities.

As our population worldwide continues to grow and age, it’s important to bring attention to issues that impact our global community. World Population Day on July 11, 2020, was established by the UN to try and solve worldwide population issues.

“The 2030 Agenda for Sustainable Development is the world’s blueprint for a better future for all on a healthy planet. On World Population Day, we recognize that this mission is closely interrelated with demographic trends including population growth, aging, migration, and urbanization.”

– UN Secretary-General António Guterres
