The County Health Rankings (CHR) calculate an Income Inequality Ratio of county household income at the 80th percentile to that at the 20th percentile. The higher the ratio, the greater the inequality between the top and bottom household incomes. For Washoe County, the 80th percentile household income in the 2018 rankings was $108,751, while the 20th percentile was $22,907. This disparity can result in increased health risks and reduced mortality, leading to financial consequences and distrust across communities. Top performing counties across the US have a ratio of 3.7, far lower than 4.7 for Washoe County.
- 5-year estimates from the American Community Survey for household incomes are used in the calculation of the ratio
