The United States has always been a bit of a moving target when it comes to who lives here. Honestly, if you look at a map of the racial makeup of the United States from 1950 and compare it to today, you’d barely recognize the data sets. We aren't just talking about a few more people moving in from overseas; we are talking about a fundamental shift in how Americans actually see themselves.
The 2020 Census was a wake-up call for a lot of people. It showed a country that is becoming "multiracial" at a rate that actually caught some demographers off guard.
The Big Shift: What the Numbers Actually Say
Let’s get into the weeds.
White Americans remain the largest group, but the share of the population identifying as White alone (non-Hispanic) has dropped. In 2010, that number was around 63.7%. By 2020? It dipped to 57.8%. That’s a massive change for a ten-year window. For the first time since the government started counting, the absolute number of people identifying as White alone actually decreased. Some of this is just biology—older generations are predominantly White—but a lot of it is about how people fill out the forms.
People are tired of picking just one box.
The "Two or More Races" population exploded. It went from about 9 million people in 2010 to 33.8 million in 2020. That is a 276% increase. If you want to understand the racial makeup of the United States today, you have to look at the "Some Other Race" category, which has now surpassed African Americans to become the second-largest racial group if you include it as a standalone category (mostly driven by Hispanic and Latino respondents who don't feel "White" or "Black" fits them).
Why the Hispanic and Latino Identity is Changing Everything
The Hispanic or Latino population reached 62.1 million in the last major count. That’s about 18.7% of the total U.S. population. But here is where it gets tricky: "Hispanic" is an ethnicity, not a race, according to the U.S. Census Bureau.

This creates a weird data loop.
You have millions of people who identify as Hispanic but then have to choose a race. Many chose "White" in the past. Now? They are checking "Some Other Race" or "Multiracial." This shift alone accounts for a huge chunk of why the "White alone" population looks like it's shrinking so fast. It’s less about people disappearing and more about people changing how they describe their heritage.
In places like California, the Hispanic population has officially become the largest racial or ethnic group, hitting about 39.4%. Texas isn't far behind. You can see the impact in everything from grocery store aisles to local political campaigning. It’s a groundswell.
The Black and Asian American Experience
The Black or African American population is holding relatively steady as a percentage of the whole, sitting at roughly 12.1% (or 14.2% if you include those who identify as Black in combination with another race). It’s a stable, vital part of the American fabric, but the growth is slower compared to Asian Americans.
Asian Americans are the fastest-growing major racial group in the country.
Between 2000 and 2019, the Asian population in the U.S. grew by 81%. We are talking about 24 million people with roots in dozens of different countries. It’s not a monolith. A person whose family came from India has a totally different economic and social experience than someone whose family came from Vietnam or Korea.

- Chinese Americans remain the largest Asian origin group (about 5.4 million).
- Indian Americans follow closely (about 4.6 million).
- Filipino Americans make up a huge segment at roughly 4.2 million.
The geography matters here too. You’ve got huge clusters in the West, but the South is seeing a massive influx of Asian American professionals moving for tech and healthcare jobs in places like North Carolina and Georgia.
The Rural vs. Urban Divide is Real
You can't talk about the racial makeup of the United States without looking at where people live. Diversity isn't evenly spread out.
If you live in a major city like New York, Chicago, or Houston, you’re living in a "majority-minority" environment. In these places, non-Hispanic White people make up less than 50% of the population. However, if you head into the Midwest or the Upper New England area—think Maine or Vermont—the numbers flip. Vermont is still about 89% White.
But even the "whitest" states are seeing change.
Small-town Iowa and Kansas are seeing growth in their Hispanic populations because of the meatpacking and agricultural industries. These towns that were dying out 20 years ago are being revived by immigrant families. It’s a quiet transformation, but it’s there.
The Accuracy Problem: Are We Even Counting Right?
There is a huge debate among experts like those at the Pew Research Center and the Brookings Institution about whether our categories are outdated.

Take the "MENA" category (Middle Eastern or North African). For decades, people from Lebanon, Egypt, or Iran were legally classified as "White" on Census forms. Most of those people will tell you they don't move through the world as White people. The government is finally moving toward adding a specific category for them, which will again shift the racial makeup of the United States data significantly in the 2030 cycle.
Then there’s the undercount.
We know that Black and Hispanic communities, particularly in lower-income areas, are historically undercounted. This isn't just a "math" problem; it's a money problem. Federal funding for schools, roads, and hospitals is tied to these numbers. If we miss a million people, those communities lose out for a decade.
The Gen Z Factor
Younger generations are the most diverse in American history.
Among Gen Z, nearly half are non-White. This is the "diversity explosion" that William Frey, a senior fellow at Brookings, often talks about. He argues that this younger, diverse workforce is the only thing keeping the U.S. economy from the stagnation we see in aging, more homogenous countries like Japan or parts of Western Europe.
They are more likely to marry across racial lines. They are more likely to check three boxes instead of one. They basically view the old-school racial categories as "kinda" irrelevant to their daily lives, even if they value their heritage deeply.
Actionable Insights for the Future
Understanding the racial makeup of the United States isn't just for history books. It has real-world implications for how you live and work.
- Localize Your Data: Don't rely on national averages. If you are a business owner or a local leader, look at your specific county’s Census "QuickFacts." The difference between a county in 2010 and 2024 is often staggering.
- Recognize the Multiracial Reality: Stop looking for "either/or." The fastest-growing segment of the population is "both/and." Marketing, healthcare, and education systems need to adapt to people who don't fit into a single bucket.
- Follow the Policy Changes: Keep an eye on the Office of Management and Budget (OMB). They are the ones who actually decide what the "boxes" on the forms look like. When they change the rules for the 2030 Census, the data will "shift" again, not because the people changed, but because the definitions did.
- Economic Adaptation: Diversifying markets aren't a niche; they are the market. Companies that fail to understand the nuances between different Asian or Hispanic sub-groups are leaving money on the table.
The U.S. is becoming a more complex version of itself. It’s messy, the data is sometimes confusing, and people’s identities are fluid. But that’s the reality of a country that’s constantly reinventing what it looks like.
