BUFFALO, N.Y. — More than three-quarters of the cities and towns across Western New York are losing population, according to a Business First analysis of new federal data.

The region's biggest cities are suffering the sharpest declines in raw numbers. Buffalo's population has been dropping by 51.19 persons per month since 2010, while Niagara Falls has been slipping by 20.49 per month.

Two prominent suburban towns — Cheektowaga and Tonawanda — are also among the leading decliners in the eight-county region.  You can see the full list on Buffalo Business First's website
