C
HistoryA character grade: shown, never part of Zwolle’s overall grade.
Louisiana towns list more on the Register than most of the country (a typical Louisiana town has 3.8 per 10,000 residents, the U.S. 2.4), so Zwolle’s 5.6 sits near the middle of its state (58% of Louisiana towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share (±2.2 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1898 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Zwolle’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The first inhabitants of the bowl-shaped area of land upon which the town of Zwolle is situated were the Mound Builders. Lured here for protection from storms, the "bowl" offered them protection. Prehistoric people built the dome-shaped mounds that line the banks of Bayou Scie and Bayou San Miguel, which form a hollow circle around the townsite. As Mound Builders, they were ancestors of North American Indians who inhabited the territory when the Europeans arrived.
