HistoryA character grade: shown, never part of Thomson’s overall grade.
Georgia towns list more on the Register than most of the country (a typical Georgia town has 10.0 per 10,000 residents, the U.S. 2.4), so Thomson’s 155 sits above most of its state (77% of Georgia towns have fewer) while its 106 historic buildings outnumber those of 90% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share is a Census survey estimate (±4.2 points). Two sources give 1837.

Thomson, originally called "Slashes", was founded in 1837 as a depot on the Georgia Railroad. It was renamed in 1853 for railroad official John Edgar Thomson. In 1870, Thomson was designated seat of the newly formed McDuffie County. It was incorporated as a town in 1854 and as a city in 1870.
The Old Rock House, built in 1785, is said to be one of Georgia's oldest documented houses with its original design intact. Built by Thomas Ansley, the home is said to be the home of ancestors of former president Jimmy Carter. Thomson is also the birthplace of Populist leader and two-time presidential candidate Thomas E. Watson.
