Population by Race
Why is Hispanic separate? Following U.S. Census methodology, Hispanic or Latino origin is an ethnicity, not a race — people of Hispanic origin may be of any race. “All” shows the racial breakdown; the Hispanic and Non-Hispanic views show ethnicity, so the two groupings overlap rather than adding up to 100%.
| Race | Population ↓ | Percentage |
|---|---|---|
| White | 1,571,369 | 84.94% |
| Two or more races | 132,283 | 7.15% |
| Other race | 83,701 | 4.52% |
| Asian | 24,932 | 1.35% |
| Native American | 22,248 | 1.20% |

Geography
Idaho has seen steady population growth over the past decades. According to the 2010 US census, Idaho had a population of 1,567,582, which was a 21.1% increase from the 2000 census count. The state currently has a healthy growth rate of 1.75%, which ranks 11th nationwide. Key factors driving Idaho's growth include the state's low cost of living, natural amenities, and technology sector in cities such as Boise. Looking deeper into the census data, we see Idaho has a relatively young population compared to national averages. The median age is 36 years old in Idaho, lower than the US median age of 38 years old. This young demographic contributes to Idaho's rapid growth.
