Fastest growing cities in Idaho
Population growth in the United States is slowing. From 2010 to 2020, the population grew by just 7.4%—the lowest rate since the 1930s. Declining birth rates, an aging population, and fewer immigrants are all contributing to historically slow growth rates. But depending on where you are in the country, it might not always feel that way.
In every state, there were cities that experienced cumulative population gains over the course of the decade. But when you look at the growth rates from year to year, cities across the country are following a similar trajectory. Small, medium, and large cities all saw declining growth since 2016. Some of the largest cities—those with populations over 1 million—have actually seen a decrease in overall population, not just slower population growth.
Stacker compiled a list of the fastest-growing cities in Idaho using data from the U.S. Census Bureau. Cities are ranked by the highest population growth from 2010 to 2020.
Many cities experienced their most significant growth within the first few years of the decade. Experts postulate that the housing bubble burst in tandem with economic hardships of the Great Recession pushed many people of home-buying age to the cities. A decade later, in the wake of the pandemic, the U.S. is in a similar position.
