Fact check: Which Massachusetts cities are split between multiple congressional districts?

1. Summary of the results

Based on the analyses provided, Fall River was the primary Massachusetts city that was split between multiple congressional districts. Multiple sources confirm that Fall River was divided between the 4th and 9th Congressional Districts for 10 years ^[1]. However, this split has been resolved through recent redistricting efforts.

The Massachusetts Legislature's new congressional district map, approved in 2021, united Fall River by placing the entire city in the 4th Congressional District ^{[2] [3]}. This change separated Fall River from New Bedford, which remains in the 9th Congressional district ^{[2] [1] [3]}.

The redistricting process addressed the previous split of Fall River, though it did so by keeping the two South Coast cities - Fall River and New Bedford - in separate districts rather than uniting them as some advocacy groups had preferred ^[3].

2. Missing context/alternative viewpoints

The original question asks about cities that "are" split, using present tense, but the analyses reveal this is primarily a historical issue that has been recently resolved. The question lacks temporal context about when these splits existed versus the current district configuration.

Alternative redistricting approaches were considered - some groups advocated for keeping Fall River and New Bedford together in the same district, but the Legislature chose to unite Fall River internally while maintaining the separation between the two South Coast cities ^[3].

The analyses suggest there may be other cities that could be split between districts (p3_s1 notes detailed information about cities and towns in each district that "can be used to infer that some cities may be split"), but the sources don't provide explicit identification of any current splits beyond the resolved Fall River situation.

3. Potential misinformation/bias in the original statement

The original question contains temporal ambiguity by asking which cities "are" split, when the most documented case (Fall River) was resolved through recent redistricting. This could mislead readers into thinking current splits exist when the primary historical example has been addressed.

The question assumes multiple cities are currently split without acknowledging that Massachusetts completed a redistricting process in 2021 that specifically addressed the most prominent split city case ^[3]. This omission of recent redistricting context could perpetuate outdated information about the state's congressional district boundaries.
