Why Boise’s Tiny Cities Are Driving Big Growth in the Treasure Valley (Star & Kuna Boom) (2026)

The growth trajectory of the Boise area continues to be a fascinating story, with smaller cities taking center stage. While Boise itself is a well-known hub, the real action seems to be happening in its surrounding areas.

The Rise of Star and Kuna

Star and Kuna, two lesser-known cities in the Ada County region, have experienced an astonishing population boom. With growth rates of 14.7% and 14.2% respectively, these cities are outpacing even the larger cities of Boise, Meridian, and Nampa.

What makes this particularly intriguing is the sheer magnitude of the increase. Star, a suburb of Boise, has seen its population more than double in just a few years, going from 11,117 residents in 2020 to over 25,000 today. Kuna, located southwest of Boise, has also witnessed a significant surge, adding nearly 5,000 residents in the past year alone.

A Granular Look at Growth

The data provided by the Community Planning Association of Southwest Idaho (Compass) offers a detailed perspective on the growth patterns within the Treasure Valley. By analyzing various metrics such as percentage change, year-over-year growth, and numeric change, we gain a comprehensive understanding of the region's development.

Personally, I find it fascinating how these smaller communities are driving such significant growth. It raises questions about the factors attracting people to these areas. Is it the promise of a quieter, more suburban lifestyle? Or perhaps the allure of new developments and amenities?

Planning for the Future

This rapid growth presents both opportunities and challenges for local authorities. As Austin Miller, a Compass planner, noted, "These distinctions underscore the importance of looking at the data from multiple viewpoints." By understanding the unique growth patterns of each community, planners can make more informed decisions about infrastructure, services, and future development.

The overall growth rate of over 20% in Ada and Canyon counties is a testament to the region's appeal. However, it also highlights the need for careful planning to ensure sustainable development and maintain the quality of life that attracts residents in the first place.

A Broader Perspective

The story of Star and Kuna's growth is not just a local phenomenon. It reflects a broader trend of suburban expansion and the appeal of smaller, more intimate communities. As cities become more congested, these smaller hubs offer a sense of community and a higher quality of life.

In my opinion, this shift towards suburban growth is an interesting development, especially in a state like Idaho, known for its vast open spaces. It will be fascinating to see how these communities continue to evolve and whether they can maintain their unique charm as they grow.
