The U.S. has just entered the new decade of the 2020s.

What does our country look like today, and what will it look like 10 years from now, on Jan. 1, 2030? Which demographic groups in the U.S. will grow the most, and which groups will not grow as much, or maybe even decline in the next 10 years?

I am a demographer and I have examined population data from the U.S. Census Bureau and from the Population Division of the United Nations.

Projections show that whites will decline; the number of old people will increase; and racial minorities, mainly Hispanics, will grow the most, making them the main engine of demographic change in the U.S. for the next 10 years and beyond.


1. There will be more of us

The U.S. population today, at the start of 2020, numbers just over 331 million people.

The U.S. is the third largest country in the world, outnumbered only by the two demographic billionaires, China and India, at just over 1.4 billion and just under 1.4 billion, respectively.

Ten years from now, the U.S. population will have almost 350 million people. China and India will still be bigger, but India with 1.5 billion people will now be larger than China, with 1.46 billion.

2. The population will get older.

The U.S. is getting older and it’s going to keep getting older.

Today, there are over 74.1 million people under age 18 in the U.S. There are 56.4 million people age 65 and older.

Ten years from now, there will almost be as many old folks as there are young ones. The numbers of young people will have grown just a little to 76.3 million, but the numbers of old people will have increased a lot – to 74.1 million. A lot of these new elderly will be baby boomers.

For example, take the really old folks – people over the age of 100. How many centenarians are in the U.S. population today and how many are there likely to be 10 years from now?

According to demographers at the U.S. Census Bureau, the number of centenarians in the U.S. grew from over 53,000 in 2010 to over 90,000 in 2020. By 2030, there will most likely be over 130,000 centenarians in the U.S.

But this increase of centenarians by 2030 is only a small indication of their growth in later decades. In the year of 2046, the first group of surviving baby boomers will reach 100 years, and that’s when U.S. centenarians will really start to grow. By 2060 there will be over 603,000. That’s a lot of really old people.

I sometimes ask my undergraduate students how many of them have ever actually seen a person 100 years old or older. In my classes of 140 or more students, no more than maybe six raise their hands. Lots more college students will be raising their hands when they are asked that question in 2060.

3. Racial proportions will shift.

In 2020, non-Hispanic white people, hereafter called whites, are still the majority race in the U.S., representing 59.7% of the U.S. population.

In my research with the demographer Rogelio Saenz, we have shown that the white share of the U.S. population has been dropping since 1950 and it will continue to go down.

Today, after whites, the Hispanic population is the next biggest group at 18.7% of the U.S., followed by blacks and Asians.

What will the country look like racially in 2030? Whites will have dropped to 55.8% of the population, and Hispanics will have grown to 21.1%. The percentage of black and Asian Americans will also grow significantly.

So between now and 2030, whites as a proportion of the population will get smaller, and the minority race groups will all keep getting bigger.

Eventually, whites will become a minority, dropping below 50% of the U.S. population in around the year of 2045.

However, on the first day of 2020, whites under age 18 were already in the minority. Among all the young people now in the U.S., there are more minority young people than there are white young people.

Among old people age 65 and over, whites are still in the majority. Indeed white old people, compared to minority old people, will continue to be in the majority until some years after 2060.

Hispanics and the other racial minorities will be the country’s main demographic engine of population change in future years; this is the most significant demographic change Americans will see.

I’ve shown above how much older the U.S. population has become and will become in the years ahead. Were it not for the racial minorities countering this aging of the U.S. population, the U.S. by 2030 and later would have become even older than it is today and will be in 2030.

  • Second-grade teacher asks her students for marriage advice. Here’s their 7 best responses.

    Children form strong worldview opinions at a very young age. Naturally curious, their thinking and insights can lead to blunt but brilliant relationship advice.

    Klarissa Trevino, a second-grade teacher, had a fun idea: to ask her students for advice ahead of her marriage. In a TikTok post, she shared some of their favorite responses, which they were genuinely thrilled to share.

    Teacher hands out worksheets

    Trevino wanted to find a way to involve her second-grade students in her wedding, so she printed out worksheets with the prompt, “The marriage advice I give my teacher is…”

    Sharing some of her favorite responses in a TikTok post, Trevino quickly went viral. She told People, “Being able to get a glimpse of their version of marriage and love was very sweet. It made me so happy that they have homes that have shown them the true meaning of it.”

    One of her favorite responses was, “do not eat each other’s snacks.”

    Marriage advice from second graders

    This is the best marriage advice these second graders had to offer—some might argue it’s as helpful and supportive as any professional’s opinion. Here are some of their responses to the prompt, “The marriage advice I give my teacher is…”:

    “to be kind and love each other.”

    “care and care for each other! Happy marriage!”

    “do not eat each others snacks.”

    “is to give her flowers.”

    “get her Starbucks evrey day.”

    “to take her on a date/ and go to a five star restraunt.”

    “care for [each other] And Love her. do not hurt her!”

    People are delighted by insightful second graders

    Viewers in the comments were delighted by the second graders’ advice, and some of their own responses were just as insightful as the kids’.

    “Kids are so smart.”

    “The best advice ever..”

    “Imagine how many marriages could’ve been saved if ppl just left eachother’s snacks alone”

    “This is legitimately better marriage advice than you see on TikTok.”

    “You should publish this, because people could really learn a thing or two from your students”

    “I’m teaching the wrong grade!!”

    “These are signs that these kids have wonderful parents and figures in there life’s …. and a wonderful teacher who loves and cares for them”

    Studies show that kids have meaningful insights

    These second graders shared straightforward, thoughtful insights. Yet research shows that children offering meaningful perspectives is nothing new. A 2025 study found that kids begin to understand other people’s feelings, beliefs, and even motivations at a very young age. They aren’t boxed in by adult expectations, which helps keep their thinking fresh and profound.

    A 2025 study found that even children as young as four understand far more than we might think. They’re capable of problem-solving and experience “aha!” moments that can make others grin.

    Kids often cut straight to the truth because they’re naturally curious. A 2025 study found that adults underestimate how organized children’s ideas can be. Like adults, kids’ beliefs shape how they act and feel, forming a worldview that is surprisingly detailed, consistent, and stable.

    These young students’ advice may seem simple, but that’s exactly what makes it so powerful. They remind us that kindness and honesty don’t require much effort to make a lasting impact on any relationship. Sometimes the truth comes from the smallest voices, and Trevino understood the value of listening.

  • Teacher spots suspicious bare feet under a school bench, but the ‘lockdown’ scare has a surprising explanation

    Teachers are trained to expect the unexpected. One day, Alissa, a history teacher who posts on TikTok under the name @teachinginstyle, looked out the window of her high school classroom and noticed a pair of bare feet hanging from a school bench.

    She knew something wasn’t right. In a split-second decision most teachers hope they’ll never have to make, she locked her classroom door. Then Alissa called the school’s safety number, which nearly triggered a lockdown.

    “One: stranger danger,” she explained in a video. “And two, I have a room full of sixteen-year-olds that I need to keep safe.”

    Nearly causing a school lockdown

    A pair of unfamiliar, bare adult feet resting on a school bench is enough to warrant further investigation by any responsible teacher.

    “Outside my classroom, there were these wooden benches. And kids would sit there during break,” she continued. “My class was quietly working, and I glance outside, and I see a pair of bare feet. Like just feet, sticking out from the bench.”

    Wondering whether it was a student and if they were okay, she headed outside to investigate, only to find an unfamiliar adult asleep on the bench. Immediately frightened, she recalled, “Three things come to mind. One: Are they alive? Two: Why is there a random adult on campus? And three: Oh my God, are we going to have to go on lockdown?”

    Alissa locked her classroom door and called the safety number, describing the situation over the phone. It turns out the feet belonged to a substitute teacher. She concluded, “It was a sub—a substitute teacher—taking a nap on the bench, like wanting to get some sun on the dogs (their bare feet). Oops. How was I supposed to know that?”

    A story that’s both chaotic and funny

    Viewers had mixed opinions about Alissa’s story. Some thought she did the right thing, while others were more concerned about the substitute teacher’s behavior. Here are some of the comments:

    “I would do the same…”

    “OK, but as a sub, I could never imagine taking a nap.”

    “not just any nap, a nap on a bench with your shoes off”

    “You are 100”

    “What on EARTH????”

    “there is NOT enough diet coke to handle this..”

    “I think anybody would’ve done the same thing in that situation”

    Prepared for school safety

    To prepare for the unexpected, teachers must go through training. A 2025 study analyzed a training program designed to help teachers and staff prepare for emergencies. The results showed that participants felt more psychologically prepared and ready to handle a crisis.

    It’s important for students to feel safe and prepared, too. But do the drills help, or do they cause more problems for kids? A 2023 study found that 27% of children said the drills made them anxious. Overall, caregivers still supported the preparation, even though some kids felt uncomfortable.

    The substitute teacher’s bare-feet fiasco turned out to be far less dangerous than it first appeared, but it highlights a real challenge teachers face every day. Alissa’s story is a lighthearted reminder of the serious nature of school preparedness, though sometimes there can be a surprisingly simple explanation.

    Anyone with concerns about handling different kinds of disasters can visit the FEMA website, where many free preparedness videos are available.

    Teacher chaperones a kindergarten field trip and shares 3 moments that perfectly capture how little kids think

    A middle school teacher, Mr. Lindsay, chaperoned his son’s kindergarten field trip to the zoo. He explains in his TikTok video 3 funny moments that perfectly capture how little kids think. If you ever need proof that young kids see the world a little differently, just listen to what they have to say on this…

    A middle school teacher, Mr. Lindsay, chaperoned his son’s kindergarten field trip to the zoo. He explains in his TikTok video 3 funny moments that perfectly capture how little kids think.

    If you ever need proof that young kids see the world a little differently, just listen to what they have to say on this field trip. From a silly animal mix-up to a candid family comment, this recap by Lindsay captures why kindergarteners are some of the funniest storytellers on earth.

    Excited To See The Leprechauns

    Lindsay describes the first experience, “A kid walks up to me, and he goes, ‘Mr. Lindsay, I can’t wait to see the leprechauns.’” Lindsay responds that the zoo doesn’t have leprechauns, to which the kindergartener says, “No, I’m serious, the leprechauns. The ones with the spots.” The child was talking about the leopards.

    A pretty cute mistake that commonly occurs with younger children. They often reshape unfamiliar words to fit sound patterns they already know. A 2023 study of speech-sound substitution in the National Library of Medicine explained that the near matches of words can be termed “markedness.” The simple mistakes gradually end after they gain better control of their mouth.

    My Stepdad Is Much Younger

    In the second story, a kindergartner walks up saying that he is thirsty. Lindsay suggests getting some water when the kid suddenly stops, stares, and says, “My one dad is 53, but my other dad, who’s my stepdad, is 21.” Lindsay offers a surprised look to the camera after recounting the unexpected honest exchange.

    A 2024 study in Nature Human Behaviour reported that researchers studied kindergarten students to see whether trust would encourage honesty. They found that kids who were shown trust cheated less often. The research suggests that when adults instill trust in young people, they can encourage greater honesty.

    Gross And Unfortunately Familiar

    In the third story, when he catches one of the kindergartners picking his nose, Lindsay tells the child not to do that. The kid then wipes the booger on the ground and exclaims, “Well, I wiped it on the ground. It’s natural.” Yikes. Lindsay wraps the video saying, “So, not much different than teaching middle schoolers, but some good moments.”

    Kindergarten-aged kids are still learning basic hygiene habits. A 2024 review in the National Library of Medicine found kids were especially vulnerable to infections because of poor hygiene. Teaching healthy practices like hand washing, body hygiene, and oral care in school helped children stay healthier.

    Kids Speak Their Truth

    There were some cute comments from fellow TikTokers who appreciated the stories and added a few of their own:

    “My son started kindergarten in the fall of 2020 so it was it all virtual on google meets. There was a kid in his class that would occasionally pop on camera in a Batman costume and say ‘I’m Batman.’ It was hilarious.”

    “Bless Kindergartner teachers- hardest job of them all!”

    “And this is why I teach kindergarten.”

    “One of my pre-k students came over to me during indoor recess, I thought the kid need help or someone hit him, he was making a face, when I asked ‘What’s wrong’ he gave a serious look and proceeds to tell me ‘I just needed to fart’ it was a nasty one”

    “Yup, sounds like kindergarteners! “

    Kindergarteners may not always know the right thing to say, but they certainly can say the honest thing. It’s a good reminder that teaching young kids means being ready for absolutely anything. Lindsay’s video offers a fun way to remind us.
