America is changing. You’ve probably heard that a thousand times, but the actual data from the U.S. Census Bureau suggests the shift is happening faster—and in more complex ways—than most people realize. When we talk about the racial composition of US population, we aren't just looking at a static pie chart. We are looking at a moving target.
Honestly, the 2020 Census was a wake-up call for demographers. It showed a country that is becoming "multiracial" at an explosive rate. For the first time in history, the White population decreased in absolute numbers since the previous decade. That's a massive deal. It isn't just that other groups are growing; it’s that the way Americans identify themselves is fundamentally shifting. People are messy. They don't always fit into the neat little boxes the government provides, and the latest numbers reflect that reality better than ever before.
Breaking Down the Big Numbers
Let’s get into the weeds.
According to the most recent comprehensive data, the White alone population remains the largest group, sitting at roughly 58.9% to 61% depending on whether you’re looking at the strict 2020 count or the 2023 American Community Survey (ACS) estimates. But here is the kicker: if you include people who identify as White in combination with another race, that number jumps.
The Hispanic or Latino population—which the Census treats as an ethnicity, not a race, though many people disagree with that distinction—is the second-largest group at about 19.1%. They are a huge driver of demographic growth in the Sun Belt. Then you have the Black or African American population at approximately 12.6% (alone) or 14.4% when including multi-racial individuals. The Asian population is around 6%, but they are actually the fastest-growing major racial group in the country right now.
It's not just a coastal thing anymore.
The Rise of the Two or More Races Group
This is where it gets interesting. Between 2010 and 2020, the "Two or More Races" population skyrocketed by 276%. That is not a typo. In 2010, about 9 million people identified as multiracial. By 2020, that number was 33.8 million.
Why the massive jump? Part of it is actual demographic change—more "intercultural" families. But a huge chunk of it is how the Census changed its questions. They made it easier for people to write in their specific lineages. People who used to just check "White" or "Black" are now checking both, or adding "Some Other Race." This shift has completely rewritten our understanding of the racial composition of US population.

It’s about identity.
If you look at states like Hawaii, the multiracial population is nearly 25%. In Oklahoma, it’s high because of Indigenous roots mixed with other backgrounds. We are moving away from a "siloed" America into something much more blended.
Regional Variations: It's Not One Size Fits All
You can't look at the U.S. as a monolith. The racial composition of US population in Maine looks nothing like it does in New Mexico.
- The Northeast: Heavily urbanized with significant Black and Hispanic populations in cities like New York and Philly, but states like Vermont and New Hampshire remain over 90% White.
- The South: This region has the highest concentration of Black Americans. In states like Mississippi and Georgia, the Black population is over 30%.
- The West: This is the most diverse frontier. California is a "majority-minority" state where Hispanics are the largest single group (about 40%).
- The Midwest: Often seen as the "heartland," it remains more White than the coasts, but cities like Chicago and Detroit are major exceptions.
The "Rural-Urban Divide" is real. Urban areas are magnets for immigration and younger, more diverse generations. Rural areas are aging faster and staying more racially homogenous. This creates two very different versions of the American experience existing side-by-side.
The Aging Factor and the "Diversity Gap"
There is a weird tension in the data. If you look at people over age 65, the racial composition of US population is overwhelmingly White (about 75% or more). But if you look at Gen Z and Gen Alpha (children born after 2010), it's a totally different story.
Among children in the U.S., "Minority" groups are now the majority.
This creates what sociologists call a "cultural generation gap." You have an older, whiter voting bloc and a younger, more diverse workforce. This influences everything from school board meetings to what shows get greenlit on Netflix. It affects the economy, too. Younger diverse populations are driving consumption in tech, fashion, and music, while older populations are focused on healthcare and retirement stability.

William Frey, a senior fellow at Brookings, has written extensively about this. He notes that without the growth of Hispanic and Asian populations, the U.S. would actually be facing a massive labor shortage and population decline similar to what Japan or Italy are seeing. Immigrants and their children are basically the "demographic engine" keeping the U.S. young.
What about "Some Other Race"?
In the last Census, "Some Other Race" (SOR) became the second-largest racial group in the country. This mostly happened because many Hispanic and Latino people don't identify with the standard categories of White, Black, Asian, or Native American. They feel like "Hispanic" is their race.
The government is actually looking at changing the rules for the 2030 Census. They might combine the race and ethnicity questions into one. If that happens, the racial composition of US population stats will look radically different overnight. "Hispanic" would likely become a race category, which would technically "shrink" the White and Black populations in the official tally.
Misconceptions We Need to Clear Up
People often think the U.S. is being "overrun" by one specific group. The data doesn't back that up. What's actually happening is a general "diversification."
For instance, Asian Americans are often treated as a monolith. But that group includes Indian Americans, Chinese Americans, Vietnamese Americans, and Filipinos—all with vastly different economic and social profiles. Indian Americans have some of the highest median household incomes in the country, while some Southeast Asian groups face much higher poverty rates.
Similarly, the "White" category is getting more complex. Many people from Middle Eastern and North African (MENA) backgrounds are currently classified as White. However, there is a huge push for a new MENA category because many of these individuals don't feel "White" in a social or cultural sense.
Business and Economic Impacts
Why does any of this matter if you aren't a data nerd? Because money follows people.

If you're in business, the racial composition of US population determines your future customer base.
- Marketing: Generic ads don't work anymore. You need cultural nuance.
- Labor: Companies that can't recruit from diverse pools are going to run out of workers.
- Real Estate: We're seeing "reverse migration." Many Black families are moving from the North back to the South (cities like Atlanta and Charlotte) for better costs of living and community ties.
The "Multicultural Economy" is estimated to be worth trillions. If you’re ignoring the fact that the median age of a White American is about 43, while the median age of a Hispanic American is only 30, you're missing the long game.
What's Next?
The 2030 Census is already being planned. Expect it to be the most "fluid" count we've ever seen. We are likely to see even more people identifying as multiracial. We will likely see a formal MENA category.
The racial composition of US population isn't just about skin color or DNA. It's about how we choose to see ourselves. As the "siloes" break down, the old ways of counting Americans are becoming obsolete.
Actionable Insights for Using Demographic Data
If you are a business owner, educator, or community leader, don't just look at national averages. National numbers hide the truth.
- Hyper-localize your research: Use the Census Bureau’s QuickFacts tool to look at your specific zip code. Diversity varies wildly by even a few miles.
- Audit your outreach: If your workforce or customer base doesn't reflect the under-30 demographic in your area, you have a looming "relevance gap."
- Follow the "Middle-Out" growth: Watch "second-tier" cities like Columbus, Ohio or Salt Lake City. They are diversifying faster than traditional hubs like LA or NYC because of lower costs.
- Update your forms: If you're still using "Race" questions from 1995 on your intake forms, you're annoying your customers. Add "Two or More" or "Prefer to self-describe" options to mirror the modern racial composition of US population.
The data is clear: the "Average American" is a profile that is currently being rewritten in real-time. Staying ahead of these shifts isn't just about being "woke" or "PC"—it's about basic literacy in the world we actually live in.
