B+
HistoryA character grade: shown, never part of Boswell’s overall grade.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Boswell’s 781 sits above most of its state (96% of Pennsylvania towns have fewer) while its 90 historic buildings outnumber those of 89% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A+. The pre-1940 share is a Census survey estimate (±7.5 points). Two sources give 1901.

What stands out about Boswell’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Boswell was settled in 1901 and incorporated as a borough on February 22, 1904. The community's founder was Thomas Taylor Boswell, the first president and supervisor of the Merchants Coal Company. Mr. Boswell's company purchased 14,000 acres (57 km2) of mineral rights under local farmland and laid out 1,600 lots for coal company houses to house the miners for its new deep coal mine just to the north. Merchants Coal, and the related Orenda Coal, were subsidiaries of Hillman Coal and Coke Company of Pittsburgh, the same firm that built the neighboring town of Jerome, Pennsylvania.
