A tennis court is almost empty in Lancaster, where ground surface temperatures reached 150 degrees on Aug. 15, 2024. Lancaster is among California cities projected to have a fast-growing population and more than 25 high heat days a year by 2050.

A CalMatters analysis shows that many California cities with the biggest recent population booms are the same places that will experience the most high heat days — a potentially deadly confluence.
Why it matters: The combination of a growing population and rising extreme heat will put more people at risk of illnesses and pose a challenge for unprepared local officials.
About the findings: California communities most at risk include: Lancaster and Palmdale in Los Angeles County; Apple Valley, Victorville and Hesperia in San Bernardino County; Lake Elsinore and Murrieta in Riverside County; and the Central Valley cities of Visalia, Fresno, Clovis and Tulare.
On a recent sunny afternoon in Lancaster, Cassandra Hughes looked for a place to cool down. She set up a lawn chair in the shade at the edge of a park and spent the afternoon with a coloring book, listening to hip-hop music.
Reaching a high of 97 degrees, this August day was pleasant by Lancaster standards — a breeze offered temporary relief. But just the week before, during a brutal heat wave, the high hit 109. For Hughes, the Mojave Desert city has been a dramatic change from the mild weather in El Segundo, the coastal city where she lived before moving in April.
Hughes, a retired nurse, is among the Californians who are moving inland in search of affordable housing and more space. But it comes at a price: dangerous heat driven by climate change, accompanied by sky-high electric bills.
A CalMatters analysis shows that many California cities with the biggest recent population booms are the same places that will experience the most high heat days — a potentially deadly confluence. The combination of a growing population and rising extreme heat will put more people at risk of illnesses and pose a challenge for unprepared local officials.
As greenhouse gasses warm the planet, more people around the globe are experiencing intensifying heat waves and higher temperatures. An international panel of climate scientists recently reported that it is “virtually certain” that “there has been increases in the intensity and duration of heatwaves and in the number of heatwave days at the global scale.”
CalMatters identified the California communities most at risk — the top 1% of the state’s more than 8,000 census tracts that have grown by more than 500 people in recent years and are expected to experience the most intensifying heat under climate change projections.
The results: Lancaster and Palmdale in Los Angeles County; Apple Valley, Victorville and Hesperia in San Bernardino County; Lake Elsinore and Murrieta in Riverside County; and the Central Valley cities of Visalia, Fresno, Clovis and Tulare.
By 2050, neighborhoods in those 11 inland cities are expected to experience 25 or more high heat days every year, according to data from researchers at Scripps Institution of Oceanography, University of Colorado Boulder and UC Berkeley. A high heat day is when an area’s maximum temperature exceeds the top 2% of its historic high — in other words, temperatures that soar above some of the highest levels ever recorded there this century. (The projections were based on an intermediate scenario for future planet-warming emissions.)
Many of these places facing this dangerous combination of worsening heat waves and growing populations are low-income, Latino communities.
“We are seeing much more rapid warming of inland areas that were already hotter to begin with,” said UCLA climate scientist Daniel Swain.
“There’s an extreme contrast between the people who live within 5 to 10 miles of the beach and people who live as little as 20 miles inland,” he said. “It’s these inland areas where we see people who…are killed by this extreme heat or whose lives are at least made miserable.”
Look up your neighborhood
While temperatures are projected to rise across the state, neighborhoods along the coast will remain much more temperate.
San Francisco, Santa Barbara and Long Beach, for instance, are not projected to experience significantly more high heat days.
San Francisco will average six days a year in the 2050s exceeding 87 degrees, compared to four days in the 2020s. In contrast, Visalia will jump from 17 days exceeding 103 degrees to 32 — more than a full month.
Unlike the growing inland populations, the cooler coastal counties, — where more than two-thirds of Californians now live — are expected to lose about 1.3 million residents by 2050, according to the California Department of Finance.
Cassandra Hughes sits in the shade in Lancaster on Aug. 15, 2024. The temperature that day reached 97 degrees — cooler than recent heat waves. She strategically cools her home to keep electric bills low. “I have air conditioning, a swamp cooler and two fans,” she said.

In California, extreme heat contributed to more than 5,000 hospitalizations and almost 10,600 emergency department visits over the past decade — and the health effects “fall disproportionately on already overburdened” Black people, Latinos and Native Americans, according to a recent state report.
City and county officials must grapple with how to protect residents who already are struggling to stay cool and pay their electric bills. Despite the warnings, many local governments have failed to respond.
A 2015 state law required municipalities to update their general plans, safety plans or hazard mitigation plans to include steps countering the effects of climate change, such as cooling roofs and pavement or urban greening projects.
But only about half of California’s 540 cities and counties had complied with new plans as of last year, according to the environmental nonprofit Climate Resolve.
The California dream or a hellish reality?
An exodus from California’s coastal regions is a decades-long trend, said Eric McGhee, a policy director who researches California demographic changes at the Public Policy Institute of California. People are moving away from the coasts, especially the Los Angeles region and Bay Area, to elsewhere in California and other states.
About 104,000 people moved from the Bay Area to the Sacramento area, the Inland Empire and the San Joaquin Valley in 2021 and 2022, and about 95,000 moved from Los Angeles, Ventura and Orange County to those same inland regions, according to data collected from the Census.
McGhee said most people moving inland are low-income and middle-income Californians looking to expand their families, find cheaper housing and live comfortably — and they’re willing to sacrifice other privileges, like cool weather.
California is “becoming more expensive, more exclusive in the places that are least likely to experience extreme heat,” Swain said. As a result, he said, “the people who are most at risk of extreme heat” — those with limited financial resources — “are precisely the people experiencing extreme heat.”
Explore high heat days
The San Bernardino County city of Victorville — which is 55% Hispanic and has median incomes far below the state average — is among California’s fastest growing areas, adding more than 12,500 new residents between 2018 and 2022. Nearby Apple Valley and Hesperia grew by about 3,000 and 6,000 people, respectively, while Lancaster, Palmdale and Visalia added between about 10,000 and 12,000.
In Victorville on an August day that reached 97 degrees, Eduardo Ceja wiped sweat from his forehead as he worked at Superior Grocers store, retrieving shopping carts.
The work is often grueling in this Mojave Desert town. He sometimes drinks five bottles of water to stay hydrated as he works, with the concrete parking lot radiating the heat back onto his skin. When he’s done pushing carts, he recovers in the air conditioned store.
The extreme heat “is noticeable. I don’t think there was a day under 100 in July.”Scott Nassif, apple valley mayorCeja, 20, moved to nearby Apple Valley about a year ago, around the same time the new grocery store opened. He used to sleep on his parents’ couch in the San Gabriel Valley town of Covina, east of Los Angeles, which is often more than 10 degrees cooler than Apple Valley on summer days. But he wanted a place to himself at a low cost, so now he pays $400 a month for a bedroom in his brother’s home.
Since he moved here, he’s observed many businesses, including his own employer, expand or open in Apple Valley.
“I notice a lot of people from L.A. are coming here,” he said. It makes sense to him. “Out here, the apartments have more space.”
Apple Valley Mayor Scott Nassif, who has lived there since 1959, said days over 100 degrees used to be rare. Now week-long heat waves above 110 degrees are commonplace.

Apple Valley Mayor Scott Nassif has seen his desert town grow and get hotter over his lifetime. When he moved to the area in 1959, only a few thousand people lived there. Now it’s home to more than 75,000 people.
Nassif remembers only a few days that would reach above 100 degrees and multiple snowstorms in the winter. Now, snowstorms are rare, and week-long heat waves above 110 degrees are commonplace.
The extreme heat “is noticeable,” he said. “I don’t think there was a day under 100 in July.”
Nassif attributes the town’s growing population to its good schools, a semi-rural lifestyle and affordable housing for families.
In the high desert town of Hesperia, growth is evident. Banners advertising “New homes!” are posted throughout the town, luring potential buyers to tract home communities. Residents are cautiously eyeing a new development, called the Silverwood Community, that has recently broken ground.
The massive, 9,000-plus acre development is authorized for more than 15,000 new homes, according to its website. A video on its website coaxes potential buyers: “True believers know the California dream is within reach.”

Hesperia, which is almost two-thirds Hispanic and also has median incomes far below the state average, is anticipating continued growth as housing costs soar in other parts of California. Its planning includes rezoning some areas to allow for higher-density housing, which could bring more affordable housing, said Ryan Leonard, Hesperia’s principal planner.
“If people are willing to make a commute to San Bernardino, Riverside or Ontario — a 45-minute to an hour commute — they can afford to buy a home here when they might not be able to afford that same home down the hill,” Leonard said.
Summer electric bills soar to $500 or more
In the California towns at most risk of intensifying heat, people already are saddled with big power bills because of their reliance on air conditioning.
For instance, households in Lancaster, Palmdale and Apple Valley pay on average $200 to $259 a month for electricity, compared to a $177 average in Southern California Edison’s service area, according to California Public Utilities Commission data as of May, 2023.
In summer months, average power use in these communities nearly triples compared to spring months, so some people’s bills can climb above $500.
You can’t not run the air conditioner all day… You wouldn’t survive otherwise. The heat is too oppressive.
— Diane Carlson, Palmdale resident
Diane Carlson moved to Palmdale, north of Los Angeles, 30 years ago. The housing was much cheaper and she wanted to move where her children could attend school near where they live.
Over the years, she’s felt the temperatures in Palmdale rise.
Carlson said her electric bill during the summers used to average about $500, a significant chunk of her household budget. About four years ago, though, she had solar panels installed on their home, which cut her bill in half.
“You can’t not run the air conditioner all day, even if you run it low,” she said. “You wouldn’t survive otherwise. The heat is too oppressive.”
With multiple days in the summer reaching at least 115 degrees, Carlson is conscious that there may be a future where Palmdale isn’t livable for her anymore.
“Will it get as hot as Death Valley?” she wondered.
Death Valley, the hottest place on Earth, reached record temperatures in July, averaging 108.5 degrees; the high was 121.9, tying a 1917 record. In comparison, Palmdale by 2050 is projected to have 25 days where the maximum temperature exceeds 105, up from nine days in the 2010s.
Carlson said she’d consider moving to the East Coast, where she’s originally from. But she’d face hurricanes rather than the heat. It all comes down to making a decision: “Which negatives are you willing to deal with?”
Hughes, who lives in subsidized housing in Lancaster, said surviving the heat means constantly checking the weather forecast and strategically cooling her home to keep electricity costs low. “I have air conditioning, a swamp cooler and two fans,” she said.
On a day when the temperature doesn’t reach triple digits, the air conditioner might stay off; she opens the windows and turns on the fans instead.
Local leaders say they know more must be done to protect their residents.
Lancaster opens cooling centers in libraries for residents who need respite from the heat. During heat waves, residents ride buses for free, and city programs provide water and other resources to homeless people.
“Is it adequate? Of course it’s not adequate,” said Mayor R. Rex Parris. “If you’ve got people who don’t read or don’t get a newspaper sitting in a sweltering apartment, the information is not getting to them and we know it.”
Parris said air conditioning is necessary for families to stay cool in the hot desert summers, but with utility costs so high, it’s becoming a luxury.
With that in mind, he said the city is prioritizing hydrogen energy, which could lower electric bills in the long-term. A new housing tract will be powered by solar panels and batteries that store power, backed up by hydrogen fuel cells, which will be cheaper than if the homes drew energy entirely from the grid, said Jason Caudl, head of Lancaster Energy.
Nassif, the Apple Valley mayor, said his town helps residents finance costly rooftop solar panels that can cut their power bills.
“Educating our public on how to save on their electric bills is a big thing, because you can’t live up here without air conditioning,” Nassif said.
Cooling centers aren’t enough to protect people
On a Saturday morning in Visalia, as temperatures climbed to 99 degrees, Maribel Jimenez brought her 2-year-old son to an indoor playground to beat the heat. She sat at a kid-sized table with her son, Mateo, as he played with toy screws and blocks.
Jimenez, 33, has lived in Visalia her whole life. She grew up on a dairy farm and remembers playing outdoors for hours in the summers. But things have changed. She can’t imagine letting her son play outdoors under the scorching sun. She worries he’s not getting the outdoor playtime he should be getting.
“It’s definitely gotten much hotter,” Jimenez said. “You can’t even have your kids outside. We want to take him out to the playground but it’s too hot. By the time it cools down in the evening, it’s his bedtime.”
Other times, she and her family go to the mall for walks, or anywhere where there’s air conditioning.
“As long as he’s out, he’s happy,” she said. “We try our best to protect him.”
The effects of extreme heat on the body can happen quickly and can affect people of all ages and health conditions. Once symptoms of heat stroke begin — increased heart rate and a change in mental status — cooling off within 30 minutes is crucial to survival, said Tomás Aragón, director of the California Department of Public Health
Many municipalities react to extreme heat by following state or county rules, which often involve opening cooling centers in public places when temperatures rise above a certain level for multiple days in a row.
“You want people to be in a space where your body can control its core temperature,” Aragón said. “It’s safer to be in an air conditioned place (that) cools your body down. That’s what cooling centers are for. I tell people, go to the supermarket, go to the library, go to a cooling center, go and just let your body cool down.”
It’s not just about preventing deaths and other terrible outcomes of heat waves … It’s really about having livable communitieswhere kids can play outside and street vendors can run their businesses without risk of overexposure.
— Ali Frazzini, L.A. County’s Chief Sustainability office
But community advocates say cooling centers are ineffective because they’re underused. Many people are unaware of them, and others have no transportation to reach them.
“I think everyone is used to that being the answer for what we do when it gets extremely hot,” said Jonathan Parfrey, executive director of Climate Resolve. “We need to expand our imagination to figure out other ways of taking care of people.”
Victorville has complied with the 2015 state law requiring plans to handle climate change, and Hesperia is in the process of updating its plans.
But Los Angeles County is an example of a local government that has gone above and beyond to comply, Parfrey said.
The county has updated its emergency preparedness plans and is in the early phases of developing a heat-specific plan for unincorporated areas, which will include urban greening and changes to the built environment to make neighborhoods cooler, said Ali Frazzini, policy director at the county’s Chief Sustainability office.
“It’s not just about preventing deaths and other terrible outcomes of heat waves, although that’s extremely important,” Frazzini said. “It’s really about having livable communitieswhere kids can play outside and street vendors can run their businesses without risk of overexposure.”
Parfrey said the state plays a role, but “they’re not in charge of the roads or building codes or where you put a water fountain or how you build a local park. All of that has to be done at a local level.”
In 2022, the Newsom administration issued an Extreme Heat Action Plan outlining state steps to make California more resilient to extreme heat. That includes funding new community resilience centers where people can cool down as well as find resources or shelter during other emergencies, such as wildfires. It’s a model that some community advocates prefer over traditional cooling centers that are underutilized.
The state has granted almost $98 million for 24 projects so far, said Anna Jane Jones, who leads development of the centers for the state’s Strategic Growth Council.
It’s definitely gotten much hotter. You can’t even have your kids outside. We want to take him out to the playground but it’s too hot.
— Maribel Jimenez, Visalia resident
In Visalia, Jimenez said her family doesn’t have many options for cool spaces where her young son can be entertained.
At home, the family uses the air conditioner sparingly and keeps the blinds closed. During a heat wave, their power bill can climb to $250. If the bills were lower, she’d use the air conditioner all the time “We have to do what we have to do,” she said.
Jimenez and her husband have thought twice about expanding their family and have floated the idea of moving somewhere else, but many of the affordable options, like Texas or Arizona, are even hotter than Visalia.
“Global warming is a thing, and the heat isn’t getting any better anytime soon,” she said. “Everybody’s paying the price.”
Find a SoCal cooling center
In L.A., Orange, San Bernardino, and Riverside counties, call 3-1-1 or call for a list of cooling centers. In the city of Los Angeles, you can also find a list of recreation centers, senior centers and libraries — all good choices for cooling off — online.
Tip: Call the center in advance to make sure seating is available.
Tip: If the center you want is at capacity, or non-operational, head to a local, air-conditioned library and cool off with a book about ice fishing in Antarctica.

Norway’s historic World Cup performance has brought together Southern California’s relatively small, but spirited Norwegian community.
Why now: They’ve been packing into a San Pedro Church, a Westside Irish bar and have taught people to row like a Viking at watch parties throughout the region, after Norway qualified this year for the World Cup for the first time since 1998.
Norwegian pride: Vilde Vevatne, who was born and raised in Oslo but now lives in L.A., said she’s proud of the team’s performance on the pitch but also their attitude outside of the matches. “ How kind and humble the team are being. … They're not bragging unnecessarily,” Vevatne said. “They're genuinely just excited to be there. They're doing their best job and not thinking they're better than anyone else.”

“This whole experience also just reminded me of why I'm proud of being Norwegian and all of these values that the society and my parents instilled upon me from a young age,” said Vilde Vevatne, who was born and raised in Oslo but now lives in L.A.
She’s proud of the team’s performance on the pitch but also its attitude outside of the matches.
“ How kind and humble the team are being. … They're not bragging unnecessarily,” Vevatne said. “They're genuinely just excited to be there. They're doing their best job and not thinking they're better than anyone else.”
Vevatne says it’s the embodiment of the Law of Jante.
“That's like an unwritten rule in Norwegian culture where we're taught from a young age — ‘Don't think you're special. Don't think you're better than everyone else,’” Vevatne said. “Just be part of the pack and just be a nice, genuine person."

And now SoCal’s Nordic community has an open invitation for anyone looking for a team to support during the quarterfinals.
Row with us. (The practice of imitating a Viking longboat of warriors rowing into battle started within the last year, but quickly became a viral phenomenon.)
“ We're a small country. We need every fan we can have,” said Petter Isaksen, who helped organize the watch parties at the Norwegian Seaman’s Church in San Pedro.
“Now there are almost no Norwegian sailors left, but there's still a lot of Norwegians in L.A. and in SoCal,” Isaksen, who works as a host at the church, said. “We're there for them as a church and as a cultural center,”
The church hosts groups for toddlers, knitting and Norwegian language classes in addition to a Sunday Lutheran service that welcomes all faiths.
And five days a week, there are waffles for sale — always heart-shaped and with your choice of goat cheese, jam or sour cream.
“We can eat several,” Isaksen said.
The Seaman's Church in San Pedro has long been a gathering place for Southern California Norwegians and has hosted watch parties since the World Cup qualifying matches.

Isaksen has followed Norway’s football team “since I was born” and started organizing the watch parties at the church during the qualifying matches.
He said dozens of people, including several new to the church, have attended each watch party for communal singing, waffle eating and rowing.
“Everyone, whether they're, like, 12 weeks or 99 years old, they're in on it,” Isaksen said. “It's so much fun, and it brings so much togetherness.”

‘Where are all the Norwegians at?’
A Culver City Irish sports bar has become another bastion of Norwegian pride during the World Cup thanks to Erik Steigen.
When he first moved to Los Angeles 30 years ago to work in the music industry, he didn’t prioritize seeking out his countrymen.
“I'm not moving to the US … to hang out with Norwegians and eat lutefisk,” Steigen said, referencing the divisive dried, lye-soaked fish. “I'm here to try to build a career and pursue my own dreams.”
But that changed about a decade ago.
Petter Wichman, right, and his son Erik, left. During the knockout game against Brazil, they lead the whole bar in a session of rowing, despite the fact that most people were cheering for their opponents.

“I started wondering, ‘Where are all the Norwegians at?’” Steigen said. He joined the board of the Seaman’s Church in San Pedro and today helps organize events through Peer Gynt LA, a cultural group that evolved from an early 20th century chapter of the Sons of Norway lodge.
“When you're from a different country — I've spent most of my life in the U.S. now — I think you become extra patriotic about your native country,” Steigen said.
So why organize a watch party at an Irish sports bar?
Steigen is a lifelong soccer fan, but when he first arrived in the U.S., the national team’s games didn’t broadcast in the states. So he adopted the Liverpool Football Club and often catches the games at Joxer Daly's in Culver City.
When people asked him where to watch Norway play, he defaulted to his home bar.
Steigen wasn’t sure if anyone would show up to watch Norway take on Iraq in their first match, but dozens did — and Norway won 4-1.
“ It's amazing how many Norwegians really exist in L.A. that you've never heard of,” Steigen said.

Elise Maeland, has attended several of the matches at Joxer Daly’s.
She’s made a handful of Norwegian friends since moving to Southern California more than a decade ago for grad school, but outside of May 17, Norway’s Constitution Day, she said there are few large Norwegian gatherings.
“I feel like that was what was really cool about the World Cup is that it really brought Norwegians together in L.A.,” Maeland said.
She hasn’t decided whether she’ll watch Saturday’s quarterfinal at Joxer Daly’s or join a larger watch party in Venice Beach.
“ I'll go where the most Norwegians go,” Maeland said.

L.A. County has confirmed another case of measles in a traveler passing through LAX and at least one other public place July 3, public health officials announced Wednesday. They’re urging people to take precautions against the highly contagious virus.
What you should know: According to the L.A. County Department of Public Health, the infected traveler arrived on British Airways Flight 281 at Gate 155 in the Tom Bradley International Terminal B on July 3. People who were at the gate between 3 p.m. and 4 p.m. may have been exposed.
Potential exposure extended to an LAX Hertz Car Rental Shuttle the same day, as well as a healthcare facility. Anyone at the shuttle from 3:30 p.m. to 4:30 p.m. may be at risk of getting measles. Public health officials did not share dates, times or other details from the affected healthcare facility.
What if I was on the flight? Passengers who were sitting near the traveler will be notified by their local health departments. The CDC and local departments regularly work together for these kinds of exposures on international flights, according to L.A. County officials.
What if I was exposed elsewhere? People who were at the rental shuttle during that time period could be at risk of developing measles. The healthcare facility is directly reaching out to patients and staff, and the Department of Public Health said it's looking into any other potential exposure locations in L.A. County.
What to watch out for: Symptoms including a fever, cough, runny nose, red eyes and a rash can show up a week to three weeks after exposure. Public health officials emphasized that if you start to show these symptoms, don't just walk into a healthcare center without calling ahead first.
The last day to monitor for symptoms from the airport terminal and rental shuttle is July 24.
How to help protect yourself: The best way to protect yourself and your family is with the measles-mumps-rubella (MMR) vaccine — so double-check your medical records. You can find more measles information from L.A. County here.

The sterile moquitoes will be released over 16 weeks.

Topline:
The San Gabriel Valley Mosquito and Vector Control District is releasing more than 480,000 mosquitoes over the next few months in an attempt to squash the local mosquito population.
Why now: Aedes aegypti mosquitoes are the culprits behind all those ankle bites. The peak of the season starts in August for the valley, lasting all the way to October (and sometimes even longer).
How it works: The district is releasing only non-biting sterile male mosquitoes. When they mate, the females don’t produce viable offspring, which will hopefully thwart the season's peak. It's a technique that's been used to some success by Riverside County.
Where is this happening? They'll be released into the unincorporated area of Basset, near Baldwin Park, which has historically seen high mosquito activity.
Read on … to learn about what you can expect.
The San Gabriel Valley is heading into peak mosquito season. If a new program goes well, there'll be even more of the pesky fliers than normal — and that's a good thing.
The San Gabriel Valley Mosquito and Vector Control District is releasing more than 480,000 mosquitoes over the next few months, with an aim to squash the invasive ankle-biters known as Aedes aegypti mosquitoes.
What’s happening
The San Gabriel Valley is one of the L.A. County areas that regularly get a lot of mosquitoes, but every season can be different. As well as being a major outdoor annoyance, Aedes aegypti is the primary carrier of dengue, and while local transmission is historically very low, the species is tough to kill off because their eggs can survive in tiny amounts of water.
That’s why the district is using a technique that introduces sterile insects into the mix. The mosquitoes they’re releasing between now and October are males that carry Wolbachia, a naturally occurring bacteria that makes them unable to have offspring with wild females.
Male mosquitoes don’t bite, so while residents may see more of them, they won’t leave a trail of those itchy bumps.
It’s a technique that’s been used elsewhere in SoCal, including San Bernardino County, with some success.

They’re going to the unincorporated community of Basset, just south of Baldwin Park, because it historically sees more activity. The area averaged more mosquitoes per trap than the district’s service area between 2020 and 2025, according to Anais Medina Diaz, communications director for the district.
Over 16 weeks, these urban bloodsuckers will be released from cardboard tubes in a 25-acre area between the intersections of East Temple Avenue, Millbury Avenue, Moccasin Street and Vineland Avenue.

They likely won’t travel much farther beyond that. Aedes aegypti populations are known for being short-distance flyers, covering about a tenth of a mile in their lifetime.
Why now?
Mosquitoes are becoming a year-around problem for Southern California, but there are still peaks to the season.
For the San Gabriel Valley, Medina Diaz said the higher Aedes activity happens between August and October.
The district’s program is also lasting longer than other programs in L.A. County for a specific reason. They want to increase the chances for sterile males to mate with wild females, which can live up to two months, according to the district.
By stopping new female Aedes aegypti mosquitoes from being born, Medina Diaz said they hope residents won’t have to deal with as many bites.
Americans have a new way to invest in their kids' futures: Trump Accounts launched over the weekend. Congress approved them last year as part of the One Big Beautiful Bill Act.
Who qualifies: If you have a child born between 2025 and the end of 2028, financial advisors say signing up for a Trump Account should be a simple decision for one reason: The child's account will automatically get a $1,000 seed contribution from the federal government. The money in these accounts will be invested in an index fund that broadly tracks the stock market. Any American citizen under age 18 can have an account, and once they turn 18, they can access that money for things like education or buying a house.
Kids born before that window aren't completely out of luck: Millions of children under age 11 will still get $250. That comes from more than $6.25 billion donated by Michael and Susan Dell of Dell Technologies. That money will only go to children who don't qualify for the federal contribution. To qualify, their families must also live in zip codes where the median family income is under $150,000.
Read on... for other things to consider when planning to save for your children.
Americans have a new way to invest in their kids' futures: Trump Accounts launched over the weekend. Congress approved them last year as part of the One Big Beautiful Bill Act, Republicans' tax and spending law. They function similarly to retirement accounts, but instead of being for adults preparing for their senior years, they're for assisting kids with the start of their adult lives.
The money in these accounts will be invested in an index fund that broadly tracks the stock market. Any American citizen under age 18 can have an account, and once they turn 18, they can access that money for things like education or buying a house. (The money can also be used for other purchases, but that comes with a tax penalty.)
The accounts function as a kind of digital "donation bucket" that many people can contribute to — kids' families, but also philanthropists, their parents' employers, and even the government. Contributions from family and other adults in the children's lives are made in after-tax dollars; contributions from others, such as employers or the government, are pre-tax. The child will only pay tax on the investment's growth once they withdraw the funding.
But there are already plenty of other options for parents to invest in, from education saving plans to their own retirement accounts. So should you sign up your family for Trump accounts? Here are four things to consider.
Your child could get free money from the federal government
If you have a child born between 2025 and the end of 2028, financial advisors say signing up for a Trump Account should be a simple decision for one reason: The child's account will automatically get a $1,000 seed contribution from the federal government.
Financial planner Michael Reynolds with Indiana's Elevation Financial did the math for Morning Edition and said that, even without any additional investments, that $1,000 would become almost $4,000 by the time a kid turns 18. (That's assuming an 8% rate of return and doesn't count the income tax that has to be paid on the growth and initial federal contribution.)
Your kid might be eligible for other donations
Kids born before that window are not completely out of luck. Millions of them under age 11 will still get $250. That comes from more than $6.25 billion donated by Michael and Susan Dell of Dell Technologies.
That money will only go to children who don't qualify for the federal contribution. To qualify, their families must also live in zip codes where the median family income is under $150,000.
And if your children don't qualify for the Dell donation, there are other options that could come your way.
Some companies are also offering contributions, like the memory chip maker Micron. It's giving $250 to up to a million children living near some of its worksites in states like Minnesota, California and New York, as a way to support the local workforce and community. Micron will also match employee donations to their own children's accounts, up to $1,000 per kid.
Other companies, including Mastercard, Uber and Visa, are also offering matches to employees.
That includes some small businesses, too. "We're going to try it out," said Luke Delorme, co-owner and director of financial planning at the finance firm Tableaux Wealth. "Maybe it'll fit into their financial picture in the future in some meaningful way."
Consider your own retirement funding first
Parents should also prioritize their own retirement before putting money away for their kids' retirement, said Carrie Joy Grimes, CEO of the nonprofit personal finance company WorkMoney.
She suggests parents max out their own retirement accounts before other options, "because what happens is we put money into our kids' stuff, and then we end up needing help in retirement — and that is a way worse financial stress on our kids."
Your kids may also benefit from a 529 education plan
Parents can already choose to invest for their children's futures through 529 savings plans. As with Trump accounts, family members can contribute to these plans with post-tax dollars.But there are differences. First, 529 plans allow kids to withdraw the money tax-free. And second, that money can only be used for education.
Parents can opt for both. Financial advisors say how families can benefit from Trump Accounts will depend on their financial situation. For wealthier families with parents who can already afford to max out their retirement accounts and put aside money in a 529, Trump Accounts are essentially an extra tax benefit for their kids.
Ray Boshara, a senior policy advisor at the Aspen Institute, says that lower-income families will primarily benefit from having that digital donation bucket that can accrue contributions for their kids. Those children might be able to start their adult lives with thousands of dollars they otherwise wouldn't have had.
"These accounts will be transformative for them," Boshara says.
