Demographics
A Portrait of Washington
Washington covers about 38.8 square miles in the central Berkshire hills, and nearly two thirds of that is conservation land, so its fewer than 500 residents live spread thin across a mostly forested town. It is an older community: the median age is 61, up from 49 a decade earlier, and more than nine in ten of its homes are owner-occupied. Figures below are from the U.S. Census Bureau and the Secretary of the Commonwealth. Follow the source links for the latest.
