Users from Springfield, Northampton and Pittsfield have posted real estate listings on Craigslist's Western Massachusetts portal in May 2015. Springfield, with a relatively large population of 153,703 people according to City-Data.com, enjoys considerable representation on the site.
The largest municipal areas covered by Craigslist's Western Massachusetts portal are Springfield, Northampton and Pittsfield. Each of these cities is its local county seat: Springfield is the seat of Hampden county, Pittsfield is the seat of Berkshire county, and Northampton is the seat of Hampshire County. These three cities feature high enough populations to ensure reliable representation on Craigslist, as evidenced by local listings that reference them.
Additional areas referenced by Western Massachusetts Craigslist posts include Amherst, Athol, Indian Orchard, Forest Park and McKnight. Many of these locations are administrative divisions or neighborhoods of larger cities; examples include McKnight and Forest Park, which are two separate neighborhoods both located in Springfield. Examples of cities other than these three that Craigslist users represent when posting to the site's West Massachusetts portal include Chicopee and Greenfield. The relatively low number of postings from these cities does not necessarily reflect lack of local activity of Craigslist in general, since Craigslist postings expire within a time frame of one week to 45 days.
