What drives McComb’s History grade

B+
HistoryA character grade: shown, never part of McComb’s overall grade.
Mississippi towns list more on the Register than most of the country (a typical Mississippi town has 71.9 per 10,000 residents, the U.S. 2.4), so McComb’s 506 sits above most of its state (89% of Mississippi towns have fewer) while its 610 historic buildings outnumber those of 98% 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 (±4.4 points). The founding year is the first post office, not a stated founding date.

McComb was founded in 1872 after Henry Simpson McComb of the New Orleans, Jackson and Great Northern Railroad, a predecessor of the Illinois Central Railroad (now part of the Canadian National Railway), decided to move the railroad's maintenance shops away from New Orleans, Louisiana, to avoid the attractions of that city's bars.
The railroad purchased land in Pike County. Three nearby communities, Elizabethtown, Burglund, and Harveytown, agreed to consolidate to form this town. Main Street developed with the downtown's shops, attractions, and business.
