How Idaho compares

Idaho's median household income is $77,800, 25th of 51 states and DC and 4% below the national median of $80,734. These are nominal dollars; living costs differ between states and aren't adjusted for here.

Reaching the top quarter of households takes about $126,819 in Idaho, compared with $141,925 nationally. 9% of households here earn $200,000+, against 13% in the US overall.

The single-year 2024 estimate puts the median at $81,166, +4% versus the five-year figure. The five-year number pools 2020–2024 and is steadier; the one-year number is more current but has a wider margin of error.

Income thresholds in Idaho

About 9% of Idaho households report income of $200,000 or more, the Census's top published bracket. By household income, the top 25% start at about $126,819, and the top 10% at about $192,967. The table marks lines that fall above $200,000 rather than guessing their value: the Census groups everyone above that amount together, so the exact top-5% and top-1% cutoffs can't be read from this data.

On Idaho's distribution, the national median income of $80,734 corresponds to roughly the top 48%.

Comparing the two lines gives a ratio of 1.64 (top quarter over median), narrower than the 1.77 seen nationwide.

Earnings by age

For individual workers, median earnings in Idaho rise from $41,549 at ages 25–34 to a peak of $55,860 at 45–54 (+34%). On average the state runs −12% relative to the US at each age, with the largest difference among workers aged 65+. These figures are personal earnings (wages plus self-employment) from Census microdata, so they're lower than household income, which can combine several earners.

Married vs. single households

If you live alone, the more relevant benchmark is the $46,275 median for single and non-family households, not the $102,154 figure for married couples (2.2× higher).

Highest- and lowest-income counties in Idaho
