Booming economies—both cities

Both Boise and Austin ranked in the top 5 for their economies, with Austin taking the cake.

Bolstered by a mass pandemic migration and tech influx, both metros are caught "mid-metamorphosis" as they quickly transform into major cities. While Austin suburbs Georgetown and Leander both saw the fastest growth of any metros from July 2020-2021 with double-digit growth, three Boise suburbs—Meridian (5.2%), Caldwell (5.2%) and Nampa (5.0%) rounded out the top 10.

Tech giants like Tesla and Oracle, alongside other developments in tech and business, helped Austin produce one of the fastest-growing economies in 2021. And with employers like Albertson's, Hewlett-Packard and Micron Technology, Boise's unemployment rate sat at 2.4% in April—well below the national average of 3.6%.

City budget, safety—Boise

With a $661.8 million budget and a projected population of just over 235,000, Boise has the third-best city budget per capita.

As the city experiences rapid change, city leaders said their budget priority was community-oriented, including "housing, transportation, environment, and more," and that 42% of the budget went to general funds.

And while Austin had a $4.5 billion budget this year, the city had to stretch that among its nearly 1 million residents. 1.2 billion—or 26%—of the budget was placed in general allocation, with two-thirds of that slotted toward public safety.

Austin remains one of Texas' safest cities, according to Police Chief Joseph Chacon, but pales in comparison to Boise. While Austin ranked 71st in safety, Boise clocked in at eighth. Boise's crime rate per 1,000 citizens was 35.5 in 2020, a 2.4% decrease from the year prior, while Austin's was 40.98 in the same time period.

Education, health—Austin

Aside from its top economy ranking, Austin also shone in its high school graduation rate, which clocked in at 1st in the US. Known as a "brain drain" city, Austin's college-town status and wealth of job opportunities have created one of the most educated populations in the U.S.

Three of the top 25 public high schools in Texas are located in Austin, and the city's education system ranked 16th. And while four of the top 10 high schools in Idaho are located in Boise, the city's overall education earned just 41st place.

Both cities are known as fitness and health havens thanks to robust outdoor amenities and health-conscious residents. But Austin still edged out its Idahoan lookalike, ranking 7th overall to Boise's 10th.

Affordability and infrastructure issues—both cities

Still, the effects of high-speed growth have done some major damage to both formerly sleepy cities.

Both cities pose higher than average incomes relative to their state. But thanks to a rapidly diminishing number of available homes for both new and old residents, both Boise and Austin ranked as the top two most overvalued housing markets in the country, according to a Florida Atlantic study.

With more and more residents priced out of homeownership and burdened with a higher cost of living, both Boise and Austin ranked below the top 30 in the financial stability index.

Both cities have seen even more development in neighboring suburbs—like Boise's Nampa, which was named the US's best-run city for the sixth year in a row—while its inner-city infrastructure often struggles to keep up with the times. While Boise's infrastructure and pollution ranked 32nd overall (Nampa ranked 77th), Austin's car-centric infrastructure ranked 45th.
