"Don't California My-"

Idaho may still be thought of as a quiet farming state by faraway onlookers, but the state was the second-fastest growing in the nation with 17.3% growth in the past decade, according to the 2020 Census. The growth has mostly been fueled by migration to Boise from priced-out West Coasters and city dwellers looking for a slightly quieter life. Texas was just behind as the third-fastest growing state with 15.91% growth.

The Boise City metro was ranked the fastest-growing in the nation by Forbes in 2018 and has hardly changed pace. Austin and Boise often share top spots on national lists; according to Business Insider, the Austin-Round Rock-Georgetown, TX metro grew 33% in the past decade with a population of 2,283,371, while the Boise metro grew 24% to 764,718 residents.

Californians accounted for 10,073 new moves to the Boise metro in 2020, up 27% from the year before. Meanwhile, move-ins to the Lone Star State literally changed national politics as California lost a Congressional seat and Texas earned two in 2021, with many of those making their way to Austin. Each state even sports popular "Don't California My Texas" and "Don't California My Idaho" slogans for disgruntled natives.

They both even had one errant political candidate who suggested a wild idea to keep the Californians out. In 2020, a Boise mayoral candidate suggested building a wall to keep out Californians, according to a City Journal article. Sound familiar? In a similar vein, an Austin City Council candidate suggested the city put up a dome around the city to do the same in 2018.

Music, Greenbelts and river tubing

With its Barton Creek Greenbelt, picturesque Hill Country views and river tubing, Austin may think it has the Northwest city beat in the outdoors department. But Boise has eerily similar attractions; the Boise River Greenbelt, for instance, provides over 25 miles of hiking, biking and swimming through the city, while those wanting to take a signature Texas river tubing trip can take to the Boise River. The region swaps Hill Country attractions for Bogus Basin, a mountain resort that serves as a skiing hub in winter and hiking oasis come summer.

The Live Music Capital can even be compared to Treasure Valley's music scene; while not as reputable as the world-renowned Austin City Limits Festival, the city's annual Treefort Music Fest is growing quickly since its founding in 2012 and has been called "the west's best SXSW alternative."

Pushing outward

Each metro is pushing outward as well. Meridian, Idaho, the state's third-largest city that sits just minutes west of Boise, was the sixth-fastest growing large city in the nation by percent change from 2010-19, according to the U.S. Census Bureau. While Meridian grew by 48.3% in the past decade, Northwest Austin suburb Cedar Park was just behind with 44.2% growth in the same time span, while Round Rock was the 13th fastest-growing with 33% growth overall.

Tech influx

Austin, sometimes known as "Silicon Hills," has experienced a wealth of new tech HQs as tech giants and startups flock to the hub. With Tesla and Oracle making waves in the Texas Capitol, it might be tough for a smaller city like Boise to compete. But a few firms, including payroll provider Paylocity, have made the move to Boise, with significant investments from fintech company Clearwater Analytics as well.

Growing pains

But everything isn't always peachy in these trendy new hotspots.

Affordability crises and infrastructure issues have racked both Boise and Austin. A 2019 report by the state of Idaho predicted that the region would add more than 100,000 residents by 2025, and the result of straining growth has been rapidly increasing rent.

A Forbes article ranked the city as the No. 1 housing market to watch in 2021, but current residents are feeling its effects. According to Apartment List, the city's rent increased more than any other city from March 2020-21 with a 39% rent jump. On Tuesday, the city said it would need 27,000 more housing units in the next 10 years to solve its housing crisis. The average one-bedroom rental in Boise costs about $1,500 monthly, $700 more than what the average Boise renter can afford.

Meanwhile, a new Zillow report says Austin could become the most expensive city outside of California as soon as the end of 2021. Austin's average one-bedroom rent is now just behind Boise at $1,442 a month, $367 more than what the average Austinite can comfortably afford. The median home price in the city of Austin hit an all-time high of $566,500 in May, rising more than $142,450 year-over-year, according to the Austin Board of Realtors.
