The U.S. Census Bureau's American Community Survey (ACS) released its five-year data release that covers a wide variety of topics, including household income, from 2015 to 2019.

Here are the 20 Seacoast municipalities with the highest median incomes from 2015 to 2019, per the ACS. For reference, the U.S. median household income for this time period was $62,843, the survey said.

Most municipalities are relatively close in median income, but the No. 1 town on this list seems to be a significant outlier.
