Alaska was the only state in America to experience a decline in median household income from 2016 to 2020, according to census data released last week, APM reports. It was also the only state to see poverty levels stay about the same. All other states saw declines in poverty.

According to the American Communities Survey, the median household income in Alaska in 2020 was about $77,790. In 2015, it was $1,500 more, at $79,258.

State economist Neal Fried with the Department of Labor says the data isn’t surprising. While the national economy was booming in that five-year period, Alaska’s economy was dragging due to increased oil production nationwide.
