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 Warren 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 any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share is a Census survey estimate (±4.5 points). The founding year is the first post office, not a stated founding date.

The story

How Warren Township came to be

From Wikipedia’s history of Warren Township.

Read it all →

The first Euro-American settlers in the township bought tracts of land beginning in the 1790s and moved into a forested wilderness from their New England homes. The Providence, Rhode Island–based company Brown & Ives was a major player in recruiting settlers, especially to the southern half of the town. Parley Coburn represented the company's interests for nearly 40 years, until his death in 1860. He was proud of the fact that at his death he had finally sold the last of the lots. It had been a difficult task because money was scarce, the original lot prices were high, and developing a living from the earth was difficult. In some instances, Brown & Ives held mortgages into the third generation of a family on the land.
