Older Americans tend to have a higher income than younger Americans, and this holds in most US states and Washington, DC.

Business Insider found the median income for full-time, year-round workers in each state among three generational age groups: millennials, Gen Xers, and baby boomers.

The gap in median income between millennials and baby boomers ranged from the older generation making about 25% more than millennials in Iowa to 65% more than millennials in Alaska.

Across the US, older workers tend to have a higher income than younger workers.

Business Insider analyzed individual-level data from the US Census Bureau's 2017 "American Community Survey" available from the Minnesota Population Center's Integrated Public Use Microdata Series and found the median total income among full-time, year-round employed workers in each state for three generational age groups: millennials (age 21 to 36 in 2017), Gen Xers (age 37 to 52), and baby boomers (age 53 to 71). Median means half the group makes below that amount and half makes above that amount.

In all 50 states and Washington, DC, the median millennial made less money than the median Gen Xer or baby boomer, and in most states boomers earned more than their Gen X counterparts.

The gap in median salary between millennials and baby boomers ranged from the median boomer making about 25% more than the median millennial in Iowa to a 65% gap between the median millennial and median boomer in Alaska.

Here's what the typical worker in each of those three generations makes in every state.
