In the southwestern portion of the state, Washington County encompassed all the most rapidly expanding cities. Washington City showed the highest population growth rate at 5.1 percent and was followed by Ivins (3.1 percent), St. George (2.0 percent), Hurricane (1.9 percent) and Santa Clara (1.6 percent).
In the remaining southwest Utah counties, few cities and towns experienced population gains. In Beaver County, estimates show contracting population for the three incorporated towns. Moreover, Boulder showed the only city-level expansion in Garfield County. In Iron County, only Kannarraville and Enoch managed notable population increases. Finally, Kanab registered the only population gains in Kane County.
