More historic than 14% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Dalzell is more historic than 14% of U.S. towns, #119 of 169 in South Carolina. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
South Carolina towns list more on the Register than most of the country (a typical South Carolina town has 3.2 per 10,000 residents, the U.S. 2.4), so Dalzell’s 6.8 sits near the middle of its state (60% of South Carolina towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.
