HistoryA character grade: shown, never part of Erwin’s overall grade.
North Carolina towns list more on the Register than most of the country (a typical North Carolina town has 12.5 per 10,000 residents, the U.S. 2.4), so Erwin’s 23.5 sits near the middle of its state (62% of North Carolina towns have fewer) while its 11 historic buildings outnumber those of 76% 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 (±5.0 points). The founding year is the first post office, not a stated founding date.

What stands out about Erwin’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Prior to Erwin, there was a colonial-era settlement in the area known as "Averasboro". The Battle of Averasborough was fought nearby during the American Civil War. In 1902, the Duke family built the Erwin Cotton Mill, which closed on December 1, 2000, due to the North American Free Trade Agreement increasing the labor costs of the mill workers, leaving Swift Textiles to relocate the mill's operations to Mexico. The new town was named "Duke" after the founding shareholders. In 1925, the name was changed to "Erwin" because of the formation of Duke University in Durham, North Carolina. Oak Grove, Averasboro Battlefield Historic District, and Downtown Erwin are listed on the National Register of Historic Places.
The Erwin post office opened in 1926, the earliest record of the town by name (U.S. post office records).
