Boston was among a handful of the nation's largest, costliest cities that saw its population shrink in the year ending July 2021, new U.S. census data show.
Suffolk County, which includes Boston and a few other close cities, lost 3% of its population, or roughly 24,000 people, in the most recent year on record.
Middlesex County, which spans from Cambridge and Somerville to Lowell, lost nearly 15,000 people or almost 1% of its population. Essex County, which covers the North Shore, and Norfolk County, including Brookline, Quincy and much of Boston’s southwestern suburbs, also suffered losses.
