HistoryA character grade: shown, never part of Clinton Township’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 Clinton Township’s 0.0 sits below most of its state (25% of Pennsylvania towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±5.4 points).

Clinton Township, which was organized in 1854, out of parts of the original Middlesex and Buffalo Townships, possesses many of the natural features which appeal to those in search of quiet homes, and these were recognized at a very early period in the settlement of the county. It is well watered land, the tributaries of Bull Creek giving necessary moisture, and its soil varies from heavy clay to sandy loam, while its coal deposits, when entirely developed, will probably make this township equal to many others in wealth
