Possibly, but I don't think so. To me it's just that it's such a very small portion of Butler County that has any real relevance/importance to the overall MSA, as noted in the thread title.
Both Washington and Beaver counties were vital to the region's history, given that they contain most of the Mon, Chartiers, and Ohio Valley industrial cites/towns. Without them, Pittsburgh doesn't exist as we know it. Those counties are "Pittsburgh" through and through.
I have Westmoreland at #4 for a few reasons: 1) It's the largest "suburban" county in population by far at around 350k 2) It's coal mining fueled the region's steel industry, with numerous old mining and manufacturing towns 2) Contains a small part of the Mon Valley (Monessen), the Yough Valley, and the entire Kiski Valley 3) Its importance as a connection between Pittsburgh and points east is illustrated by its rail lines and existing US highways 22, 30, the PA Turnpike, and I-70.
Butler has never really had too much relevance/importance, or even connection to, the Pittsburgh region at all until the 1980s, after I-79 was built. It was (and mainly still is) rural land. Butler City was the only sizable spot and it was only connected to the Pittsburgh area by a rural state highway Rt. 8, with nothing but farmland in between for the most part. It's very clear just by looking at the patterns and age of development, South Hills & River Valleys vs. North Hills.
Sure, the southwest corner of the county is now developed with Cranberry/Mars/Seven Fields, but that is really just Allegheny County sprawl that pushed over the border around the I-79/Turnpike/US19 corridor. A decent-sized portion of "Cranberry" is actually in Allegheny County. It's still just such a tiny portion of the county that has any true importance or relevance to the MSA.
The only reason I don't list Fayette above Butler is due to Butler's growth and significant employment centers there now.
