The United States is currently going through a massive demographic shift that honestly hasn't been seen since the early 20th century. People talk about it all the time on the news, but the actual American population by race is way more nuanced than just "the country is getting more diverse." It's about identity, how we check boxes on census forms, and where people are actually moving.
We aren't just a melting pot anymore. We're more like a complex mosaic where the tiles are constantly being reshuffled. If you look at the latest U.S. Census Bureau data and the projections coming out of the Brookings Institution, the numbers tell a story of a country that is becoming "multiracial" faster than almost anyone predicted.
It’s not just about who is being born. It’s about how people choose to see themselves.
The Big Picture of American Population by Race
For a long time, the White population was the overwhelming majority. It still is the largest group, but the "White alone" category has seen a decline for the first time in history. According to the 2020 Census, the White population decreased by about 8.6% since 2010. That's a huge deal. Right now, the White non-Hispanic population sits at approximately 57.8%.
Wait, why does that matter?
Because for the first time since the government started counting in 1790, the White population didn't grow. It shrank. Meanwhile, the Hispanic or Latino population—which is an ethnicity, not a race, though that’s a whole different headache for data nerds—now makes up about 18.7% of the total.
The Rise of the Two or More Races Group
If you want to see where the real action is, look at the "Two or More Races" category. This group exploded. It went from about 9 million people in 2010 to a staggering 33.8 million in 2020. That is a 276% increase.
Does this mean everyone suddenly started having multiracial children? Not exactly. A lot of it comes down to how the Census Bureau changed their questions. They made it easier for people to say, "Hey, I'm not just one thing." People who previously just checked "White" or "Black" are now acknowledging their full heritage. It's a shift in identity as much as it is a shift in biology.

Breaking Down the Major Groups
Let's look at the Black or African American population. It's relatively stable but growing slowly, making up about 12.1% to 12.4% of the country depending on whether you count those who identify with other races too. What’s interesting here is the geography. We’re seeing a "New Great Migration" where Black Americans are moving back to the South, specifically to cities like Atlanta, Charlotte, and Houston, leaving behind the old industrial hubs of the Midwest.
Then you have the Asian American community.
This is the fastest-growing major racial group in the U.S. between 2010 and 2020. They now represent about 6% of the American population by race. The growth is driven largely by immigration from countries like India, China, and the Philippines. Unlike some other groups, the Asian population is highly concentrated in urban areas and tech hubs, which gives them a massive amount of economic and political influence in states like California, New Jersey, and Washington.
The Hispanic/Latino Factor
You can't talk about U.S. demographics without hitting the Hispanic population hard. They accounted for about half of the total U.S. population growth over the last decade. But here's the kicker: the source of that growth has shifted. It’s no longer just about people crossing the border. Most of the growth now comes from natural increase—births happening right here in the States.
The median age of Hispanic Americans is about 30. For White non-Hispanic Americans, it’s 44. That’s a generation gap that defines everything from what’s on Netflix to who wins the next election.
Why These Numbers Are Kinda Controversial
Data isn't just numbers. It's politics.
The way we categorize the American population by race is constantly being debated. For example, there is a huge push to include a "Middle Eastern or North African" (MENA) category. Currently, people from these regions are officially told to check the "White" box. Many of them feel that doesn't represent their lived experience at all.
There's also the "Some Other Race" category. In the last Census, this became the second-largest racial group in the country. That's a total failure of the categorization system. Basically, millions of people (mostly Hispanic) looked at the options provided by the government and said, "None of these fit me."
- The "White alone" population is aging and shrinking in absolute numbers.
- The under-18 population is now "majority-minority" in many states.
- Multiracial identity is the new norm for Gen Z and Gen Alpha.
The Economic Reality of the Shift
This isn't just a social studies project. It’s business. If you’re a company and you aren’t looking at these numbers, you’re basically ignoring your future customers. The combined buying power of Hispanic, Black, and Asian Americans is in the trillions.
In cities like Houston, Miami, and Los Angeles, the "minority" is the majority. This affects everything. It affects what grocery stores carry. It affects which languages are on the signs at the bank. It even affects how houses are built, as multi-generational living becomes more common among certain cultural groups.
Economists like William Frey from the Brookings Institution have noted that the "diversity explosion" is actually the only thing keeping the U.S. from the kind of population collapse we're seeing in Japan or Italy. Without immigration and the higher birth rates in minority communities, the U.S. labor force would be in serious trouble.
Regional Differences Are Wild
Demographics don't hit every place the same way. While the coastal states are super diverse, the "Center" of the country—the Midwest and parts of the Great Plains—remains much more White. However, even there, things are changing. Small towns in Iowa or Kansas that were 99% White thirty years ago are now seeing huge influxes of Hispanic workers in the meatpacking and agricultural sectors.
It creates a sort of "cultural lag." The politics of a place often take twenty years to catch up to the actual makeup of the people living there.

What Most People Get Wrong About 2045
You've probably heard the headline: "America will be majority-minority by 2045."
It’s a popular talking point, but it's a bit of an oversimplification. It assumes that "White" and "Minority" are two fixed, opposing camps. They aren't. Intermarriage rates are at an all-time high. When a person with a White mother and a Hispanic father grows up, how do they vote? How do they identify?
History shows that the definition of "White" actually expands over time. A hundred years ago, Irish and Italian immigrants weren't considered "White" in the way we think of it today. They were distinct "races" that eventually blended into the majority. We might be seeing that happen again, where the boundaries of these categories blur so much that the 2045 prediction becomes meaningless.
Practical Steps for Navigating This Data
If you’re trying to use this information for business, research, or just to be a more informed human, don’t just look at the national average. National averages are mostly useless.
Look at the county level.
The American population by race varies wildly from one zip code to the next. If you're marketing a product, a strategy that works in Brooklyn will fail miserably in rural Ohio. Use the Census Bureau’s QuickFacts tool to see the actual breakdown of your specific area.
Understand the "Hispanic" distinction.
Always remember that Hispanic is an ethnicity, not a race. You can be Black and Hispanic, White and Hispanic, or Indigenous and Hispanic. If you're analyzing data, checking for "White alone, non-Hispanic" is the only way to get a clear picture of the European-descended population.
Focus on age, not just race.
The biggest takeaway from the current demographic shift is the age gap. The "diversity" of America is concentrated in the youth. If your audience is under 30, you are talking to the most diverse generation in human history. If they are over 65, the world still looks a lot like it did in 1970.
Stay updated on policy changes.
The Office of Management and Budget (OMB) is constantly tweaking how these questions are asked. Even a small change in a checkbox can "create" millions of people in a category overnight. Always check the methodology of any study you read.
The U.S. is changing. It's getting older, it's getting more "mixed," and it's moving South and West. Whether you're looking at the American population by race for school, work, or just curiosity, the real story is that we are becoming a country that defies easy categorization.
The boxes are getting smaller, but the people are getting bigger.
