Fastest-growing US state: Map reveals where the population is booming
Birthrates in the United States have reached a historic low, with women having an average of 1.6 children in their lifetime. However, while some states have seen significant reductions in population growth, others are seeing their populations boom.
Since 2020, one of the fastest growing states in the U.S. has been Idaho, increasing by 6.2 percent between 2020 and 2023, according to data from the U.S. Census Bureau. This represents a rise from 1,849,339 in July 2020 to 1,964,726 in July 2023. However, this growth has not been even across the state.
The map below shows which Idaho counties are growing the fastest:
The fastest population growth was seen in Camas County, with a 14 percent increase between 2020 and 2023. This was followed by Boundary County at 12 percent. Tied for third place was Adams County, Boise County, Bonner County, and Canyon County, with an 11 percent growth rate.
So, what might be driving these increases?
According to researchers at the University of Idaho, more than a quarter of the state’s growing population are new to the state. By analyzing vehicle registration and license surrender data from the Idaho Transportation Department between 2011 and 2021, the team found that nearly half a million Idaho residents had moved to the state in the last decade.
“We’re not in the middle of nowhere anymore,” Jaap Vos, a professor in the College of Natural Resources at the University of Idaho who focuses on planning, said in a statement on the university’s website in 2022. “We’re actually in the middle of all the action. If you look at the numbers, you can see we are getting new people coming in constantly.”

According to the Idaho Department of Labor in March 2023, net migration into the state accounted for 88 percent of Idaho’s population growth between 2021 and 2022, the majority of which were U.S. citizens moving in from other states. The remaining 12 percent was from natural change when birth rates overweigh deaths.
While Idaho is seeing this influx of new people, many longstanding Idaho residents have been increasingly moving elsewhere, resulting in a significant reshaping of Idaho’s demographics.
According to a January interview with Matthew Hurt, an economist at the Idaho Division of Financial Management, with the Idaho Statesman, two thirds of Idaho’s predicted revenue growth through the 2028 fiscal year will be added through migration, with as many as one third of migration in Southwest Idaho coming from California.
For every Idaho family that moves to California, Idaho gets three back, Hurt added.
“California totally dominates the net migration story, and it really is because Californians come to Idaho,” he said. “Idahoans don’t really go to California.”

Idaho is in for a streak of clear skies next week
After a round of showers came through this week, the Gem State is staying dry and clear for next week.
Temperatures finally started to feel winter-like as we take a tumble this weekend. Consistent 40’s the highs, and 20’s the lows.
Conditions on the valley floors are not expected to get past the mid 40’s. Showers appear to be nonexistent for the next 7 to 10 days.
We will also see some air stagnation in our area, meaning that as a high-pressure ridge moves in, not too much change is expected in the air. So, air quality may take a bit of a fall.
Not much more than cold and dry air is on the way for Idaho, but at least the sun will shine for most of the forecast.
Have a great weekend and stay warm!

Interstate 84 near Mountain Home back open after utility work
MOUNTAIN HOME, Idaho (KMVT/KSVT) — Interstate 84 near Mountain Home is back open after crews closed the freeway due to utility work.
Crews closed westbound and eastbound lanes on Saturday morning from milepost 90 to milepost 95 due to Idaho Power working on power lines in the area, according to the Elmore County Sheriff’s Office. All lanes are now back open in both directions.
The sheriff’s office and the Mountain Home Police Department apologized for the inconvenience, saying they were just informed of the closure on Saturday morning.
More information regarding road closures and traffic conditions can be found at the Idaho Transportation Department’s 511 map.

Idaho murder victims’ families file wrongful death lawsuit against Washington State University
The families of the four University of Idaho students killed in a brutal 2022 stabbing attack have filed a wrongful death lawsuit against Washington State University (WSU), alleging the school ignored repeated warning signs about Bryan Kohberger.
The civil complaint, filed Jan. 7 in Skagit County Superior Court, was brought by Steve Goncalves, father of Kaylee Goncalves; Karen Laramie, mother of Madison Mogen; Jeffrey Kernodle, father of Xana Kernodle; and Stacy Chapin, mother of Ethan Chapin.
The lawsuit accuses WSU of gross negligence, wrongful death and violations of federal education laws, including Title IX. The plaintiffs are seeking unspecified monetary damages.
Attorney Robert Clifford, senior partner at Clifford Law Offices, said that the decision to leave damages “unspecified” is a strategic norm in high-stakes litigation because it prevents the focus from shifting towards sensationalism and keeps the decision firmly in the hands of the jury.
“Ultimately, that’s to be determined and answered by the jury,” said Clifford, who is not involved in the lawsuit. “But you have some compelling facts and the liability is going to depend on the strength of what the school knew.”
Despite Kohberger’s guilty plea in the murders, Clifford explained the civil case remains strong because the families face a lower burden of proof – requiring only a preponderance of evidence to establish the university’s liability.
“The mere fact that he pled guilty might not even be admissible in the civil proceeding because he’s not the defendant, right? If he is a defendant in the civil proceeding, then his plea of guilty will be important. And indeed, this school might try to use that to say, ‘See, it wasn’t our fault. He admits that it was his fault.’ But the bar is different for someone in a criminal proceeding than it is in a civil proceeding.”
According to the lawsuit, WSU hired Kohberger as a teaching assistant in its criminal justice and criminology department and provided him with a salary, tuition benefits, health insurance and on-campus housing.
The victims’ families allege the university had extensive authority over Kohberger’s conduct but failed to act despite mounting concerns.
Here’s the latest coverage on Bryan Kohberger:
The complaint says WSU received at least 13 formal reports accusing Kohberger of threatening, stalking, harassing or predatory behavior toward female students and staff during the fall 2022 semester. The families argue university officials did not meaningfully investigate those complaints or remove Kohberger from campus before the murders – even though they had the authority to do so.
The lawsuit also alleges that the university failed to use its own threat-assessment systems designed to identify individuals who pose a risk of violence, even as concerns about Kohberger escalated. Instead, the families claim, the university continued to employ him, house him and give him access to students.
“The murders were foreseeable and preventable,” the complaint states, alleging WSU prioritized avoiding legal and reputational risk over student safety.
The lawsuit also alleges broad failures within the public university, including alleged dysfunction within campus police and compliance officers who are responsible for handling accusations of misconduct, including sexual harassment and stalking.
Kohberger pleaded guilty in July 2025 to four counts of first-degree murder and burglary. He was sentenced to four consecutive life terms without the possibility of parole.
Prosecutors said Kohberger stabbed the four students in the early morning hours of Nov. 13, 2022, inside an off-campus rental home in Moscow, Idaho, just miles from the WSU campus in Pullman, Washington.
Kohberger was arrested in Pennsylvania in December 2022 following a multi-state investigation.
Authorities linked him to the crime through DNA evidence, surveillance video and cellphone data showing repeated late-night trips near the victims’ home.
WSU has not yet filed a response to the lawsuit. Fox News Digital has reached out to WSU for comment.
