U.S. Population Change in the Last Decade, by State
The U.S. is the third most-populated country in the world, behind only two Asian giants of China and India respectively. But within the country, a lot can change in 10 years, and populations are especially mutable in nature.
As people moved in and out of certain areas for both lifestyle and economic reasons, which U.S. state populations fluctuated the most?
Drawing from the latest Census Bureau data, we look at how each state’s resident populations evolved over the past decade. But first, a blast from the past.
Historical Trends: U.S. Population Since the 1930s
Population growth trends in the U.S. have been closely tied to the economic ebbs and flows experienced by the nation. In one stark example, the country’s 10-year population growth rate plummeted to just 7.3% due to the Great Depression.
This was later offset by the post-WWII “Baby Boom”, during which birth rates soared once more, bumping up the population 10-year growth rate to 18.5% in the 1950s. The Baby Boomer generation now wields the most influence over the U.S. economy and society thanks to the favorable economic conditions in which they were born.
However, U.S. population growth rates recently hit new lows—the slower pace in the 2010s is rivalling that of the 1930s. According to Brookings, there area few factors at play:
- Falling fertility rate
- An increase in deaths (aging population, overdose deaths)
- Lower immigration rate
With all this in mind, how does the current landscape of the U.S. population by state look?
The Entire U.S. Population by State in 2020
The U.S. experienced 7.4% population growth between 2010-2020, which equates to the addition of 22.7 million people.
An impressive one-tenth of this growth occurred in California, and it remains the most populous state, rising above 39.5 million people in 2020. The SoCal megaregion—Los Angeles and San Diego—alone contributes more than $1.4 trillion to global economic output.
|Area||2020 Census Resident Population||Numeric Change (2010-2020)||% Change (2010-2020)|
|District of Columbia (Territory)||689,545||87,822||14.6%|
|Puerto Rico (Territory)||3,285,874||-439,915||-11.8%|
*Note: U.S. total and 10-year percentage change includes District of Columbia but excludes Puerto Rico
Overall, there’s been a significant shift in population towards the Sun Belt region (stretching from Southeast to Southwest), where 62% of the U.S. now resides. Let’s take a closer look at the biggest gainers and decliners over time.
Gainers: Utah, Texas
Utah saw the quickest population growth rate of 18.4% in the last decade. Drawn in by strong economic prospects, net migration into the state is balancing out a decline in births. What’s interesting is that 80% of Utah’s population is concentrated in the Wasatch Front – a metro area anchored by Salt Lake City and the chain of cities and towns running north and south of Utah’s largest city.
A little further south, Texas swelled by almost 4 million residents in the last 10 years. Much of this growth took place in the “Texas Triangle”, which contains Dallas, Houston, San Antonio, and Austin. This booming region of the country contributes over $1.2 trillion to global economic output.
Decliners: West Virginia, Puerto Rico
West Virginia lost the most people in a decade, seeing a numeric population decline of 59,278. This may be explained by an aging population—16% of West Virginians are 65 years old and above.
When territories are also taken into account, Puerto Rico saw the biggest percentage decline of 11.8%, or close to 44,000 people over 10 years. Many of them moved into the mainland, and especially into Florida, after two hurricanes hit the island in 2017.
Full Speed Ahead: States Competing On Forward Momentum
By 2025, California will be home to five of the fastest-growing urban U.S. cities. The unstoppable growth of the tech industry in Silicon Valley is partly behind this, as many people flock to the West Coast to fill the shoes of highly skilled jobs required.
But could Silicon Valley one day lose its steam? Current and projected population growth in Texas is bolstering its tech potential too—in fact, it’s been dubbed the next “Silicon Hills”, with many tech companies from SpaceX to Oracle choosing to camp out in Austin instead.

All World Languages, By Native Speakers

Languages provide a window into culture and history. They’re also a unique way to map the world – not through landmasses or geopolitical borders, but through mother tongues.
The Tower of Babel
Today’s infographic from Alberto Lucas Lopez condenses the 7,102 known living languages today into a stunning visualization, with individual colors representing each world region.
Only 23 languages are spoken by at least 50 million native speakers. What’s more, over half the planet speaks at least one of these 23 languages.
Chinese dominates as a macrolanguage, but it’s important to note that it consists of numerous languages. Mandarin, Yue (including Cantonese), Min, Wu, and Hakka cover over 200 individual dialects, which vary further by geographic location.
|Country||Native Chinese speakers (millions)|
|🇭🇰 Hong Kong SAR||6.5|
|🇲🇴 Macau SAR||0.5|
Chinese is one of the most challenging languages for English speakers to pick up, in part due its completely unfamiliar scripts. You’d have to know at least 3,000 characters to be able to read a newspaper, a far cry from memorizing the A-Z alphabet.
Spanglish Takes Over
After Chinese, the languages of Spanish and English sit in second and third place in terms of global popularity. The rapid proliferation of these languages can be traced back to the history of Spanish conquistadors in the Americas, and British colonies around the world.

Today, Spanish has 399 million native speakers, but these are mostly concentrated in Latin America. English has 335 million native speakers under its belt, with a widespread reach all over the globe.
Two Worlds, One Family
While the visualization makes all the world languages seem disparate, this linguistic family tree shows how they grew from a common root. It also explains how languages can evolve and branch out over time.

This linguistic tree also includes many languages that are not on the large visualization of 23 mother tongues. Some of them might be considered endangered or at risk today, such as Catalan or Welsh. However, with globalization, a few interesting linguistic trends are arising.
1. Language revival
Certain enclaves of marginalized languages are being preserved out of pride for the traditional and cultural histories attached.
While Catalan was once banned, its rebirth is a key marker of identity in Barcelona. More than 150 universities teach Catalan worldwide. In the case of Welsh, a mammoth university project plans to make sure it does not die out. Researchers are compiling ten million Welsh words to preserve the past, present, and future of the language.
2. Language forecast
At this point in time, English is the lingua franca – adopted as a common language among speakers with different mother tongues. However, this status might soon be fuzzier as demographic trends continue.
The rise of China is an obvious one to consider. As China continues to increase its economic might and influence, its languages will proliferate as well.
At the same time, 26 African countries are projected to double their current size, many of which speak French as a first language. One study by investment bank Natixis suggests that Africa’s growth may well bring French to the forefront – making it the most-spoken language by 2050.
Could French provide a certain je ne sais quoi that no other world language can quite replace?

Ranked: The World’s Fastest Growing Cities
Nearly 60% of the world’s population lives in cities and this trend is not slowing down—take a look at the world’s 20 fastest growing cities.
Ranked: The World’s Fastest Growing Cities
By 2025, the world’s population will reach over 8.1 billion people.
Most of that population growth will be concentrated in cities across Africa and Asia. To help paint a detailed picture, this map uses data from the United Nations to rank the top 20 fastest growing cities in the world in terms of average annual growth rate from 2020 to 2025.
Full Speed Ahead
The majority of the world’s fastest growing cities are located in Africa—in fact, 17 of the 20 are located on the continent, with four of the 20 cities being located in Nigeria specifically.
Population growth is booming across the entire continent, as many countries retain high birth rates. According to the World Bank, the 2019 fertility rate (births per woman) in Sub-Saharan Africa was 4.6, compared to the global fertility rate of 2.4.
|City||Country||Continent||Annual Growth (2020-2025p)|
|Kabinda||🇨🇩 Democratic Republic of Congo||Africa||6.37%|
|Bunia||🇨🇩 Democratic Republic of Congo||Africa||5.63%|
|Goma||🇨🇩 Democratic Republic of Congo||Africa||5.14%|
Nigeria’s economy is largely based on petroleum which has resulted in the country becoming one of the strongest economies in Africa. This, coupled with a high birth rate and a resulting young population, has given the country a strong and rising workforce.
However, the population growth in Nigeria is both a blessing and a curse. The success of the economy, among other factors, has resulted in excessive rural-to-urban migration. This mass exodus from rural areas has led to less farming, which means the country now needs to import basic food staples at a high cost.
In Mozambique, Tete and Quelimane are growing 5.56% and 5.14% respectively. The country is expected to experience strong economic growth after facing contractions due to the pandemic. Forecasts predict that the Mozambiques’s economy will grow 4% by 2022.
Implications of Fast Growth
All of the top 20 fastest growing cities are located in either Africa or Asia, and they are far outpacing growth on other continents, such as Europe, for example.

By 2050, Sub-Saharan Africa will be home to close to 2 billion people and roughly half will be under the age of 25. This represents an enormous labor force and opportunities for innovation and growth. In fact, in navigating the pandemic, Africa is already starting to capitalize on digital advances in both traditional and new sectors.
China has its eye on Africa, as evidenced through their multiple investments in infrastructure projects in the continent. Additionally, NATO countries have recently committed to investing similar amounts in Africa to counter China’s influence.
In spite of the economic potential, increased city sizes could be problematic for some of these countries. They will need to adapt to the issues associated with mass urbanization, like pollution, overcrowding, and high costs of living.
Population booms can lead to massive economic growth, a larger (and younger) working population, and a growing domestic consumer market.
As the aforementioned cities continue their rapid expansion, and as people continue to flock to growing megacities in Africa and Asia, it could represent the beginning of an important economic shift that is worth keeping an eye on.
