Using IRS data, we were able to get a snapshot of how much money people from Washington state earned in 2016, the most recent year they have numbers for. And of the top 20 wealthiest zip codes in the state, all 20 have an average income of more than $130,000.

The average income is calculated as an average of all the tax returns from each zip code.

While zip codes can often cover more than one locale, this (and last) year's two highest slots go to neighborhoods that occupy the entirety of their zip codes -- and they're not exactly surprises: Mercer Island and Medina.
