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 Targets Japanese Beetle in Caldwell to Protect Agriculture
POCATELLO, Idaho — Idaho agriculture officials are taking aggressive action after five Japanese beetles, a highly destructive invasive pest, were detected in Acequia near Rupert, according to information provided by the Idaho Farm Bureau Foundation.
The Idaho Farm Bureau Federation reports the Japanese beetle, a non-native insect that feeds on more than 300 species of agricultural and ornamental plants, poses a significant threat to Idaho agriculture. In response to the discovery, the Idaho State Department of Agriculture (ISDA) has deployed about 800 traps in the Rupert area to determine the extent of the infestation.
“We take an aggressive approach to make sure we don’t see those numbers boom before we can actually handle the situation,” said Vene Stewart, an ISDA pest survey and detection specialist helping lead eradication efforts.
Stewart said Japanese beetles are not selective feeders.
“They eat about 300 different types of flowering plants. Pretty much anything that flowers, they would love to demolish,” Stewart said.
The ISDA is also conducting eradication efforts in Caldwell and Pocatello. Last year, the department detected 160 Japanese beetles in Caldwell and 12 in Pocatello. Residents in those areas, as well as Acequia, may notice the yellow traps used to monitor the pest’s presence.
“We will be treating all three of those areas this year,” Stewart said.
Caldwell, like Acequia, is located in a major agricultural region. About 700 traps have been placed throughout the Caldwell area.
“The Caldwell infestation isn’t moving at all,” Stewart said. “In fact, where we are finding the beetles is getting to be a smaller and smaller area. You like to see that.”
The department has also placed approximately 550 traps in the Pocatello area.
Stewart said eradication efforts require ongoing monitoring and treatment.
“It’s unfortunately not something that we can just treat one time and assume everything’s going to be (OK) the following year,” she said. “It’s something we’re going to have to keep up on.”
According to a recent University of Idaho study, agriculture accounts for one in every nine jobs in Idaho, 17% of total sales and 12% of the state’s gross domestic product.
ISDA officials have worked to eliminate Japanese beetles wherever they appear in Idaho. About 15 years ago, large numbers of the beetles were detected in the Boise area. Officials say the state’s eradication campaign there resulted in no detections in Boise for several years. According to ISDA officials, the effort became the largest documented Japanese beetle eradication in U.S. history.
“We definitely want to protect our agriculture, especially in Caldwell where it is such an agriculture-(rich) area,” Stewart said. “It’s definitely important to the residents and the farmers out there to make sure that we keep our eye on it and make some progress.”
Stewart said the department’s eradication efforts have received support from farmers, local residents and city officials.
Adult Japanese beetles are about a half-inch long with metallic green bodies and copper-colored wing covers. The insects can skeletonize leaves and leave holes in plants while feeding.
Officials warn that if the beetle were to establish a permanent presence in Idaho, it could lead to reduced crop production, increased pesticide use and potential market restrictions through quarantine measures.
Native to Japan, the beetle was first detected in the United States in 1916 and is now found throughout most states east of the Mississippi River.
Although Idaho has preventative measures in place to reduce the risk of introduction from infested states, ISDA officials believe the beetles still arrive by hitchhiking with people moving from affected areas.

3 Colorado motorcyclists killed in Idaho crash; Colorado driver arrested
DENVER (KDVR) — Three Colorado motorcyclists died on Tuesday in northern Idaho after a pickup truck driver, also from Colorado, hit all three while trying to pass another vehicle, according to the Idaho State Police.
The crash happened at about 4 p.m. Tuesday outside the town of Kooskia on U.S. 12, police said. The pickup truck driver, identified as a 60-year-old Colorado Springs woman, was headed west on the highway when she crossed the double yellow line in a no-passing zone while trying to pass another vehicle.
She then collided head-on with the three motorcycles that were headed east on the highway.
The three motorcyclists died at the scene. The Idaho County Coroner identified the motorcyclists as: Ethan Powers, 35, of Timnath, Jeremy Coleman, 45 of Berthoud, and Nathan McCormick, 26, of Loveland.
The Colorado Fraternal Order of Police later identified Coleman and Powers as a sergeant and deputy with the Larimer County Sheriff’s Office and McCormick as Coleman’s son-in-law.
“Our thoughts and prayers are with their families, friends, coworkers, and the members of FOP Lodge 4 as they face the difficult days ahead,” the union said. “The law enforcement profession is built on service, sacrifice, and commitment to others. Sgt. Coleman and Deputy Powers dedicated their lives to protecting their community, and their impact will continue to be felt by those who had the privilege of serving alongside them.”
The truck driver was taken to a hospital for medical evaluation before being released then arrested. She was booked into the Idaho County Jail on probable cause for three counts of vehicular manslaughter, police said.
