From 2016 to 2017, the middle class grew in 30 states, but only caught up to 2000 levels in two places, Nebraska and the District of Columbia. The map shows each state’s percentage of population living in the middle class, by year.

Note: For purposes of this analysis, Stateline defines "middle class" as those households earning between two-thirds and twice the state's size-adjusted median household income. Household income is size-adjusted to represent a three-person household.
