History grade
What drives Louisa’s History grade
On its age, its old homes and the National Register, Louisa is more historic than 84% of U.S. towns, #22 of 142 in Kentucky. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.
A−
HistoryA character grade: shown, never part of Louisa’s overall grade.
Kentucky towns list more on the Register than most of the country (a typical Kentucky town has 29.9 per 10,000 residents, the U.S. 2.4), so Louisa’s 132 sits above most of its state (73% of Kentucky towns have fewer) while its 34 historic buildings outnumber those of 82% 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 (±7.2 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

Louisa, building by building, 1907–1921
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
The origin of the city's name is unclear. Theories include that it was named for Louisa County, Virginia, after Louisa Swetnam, one of the first white children born in the area, or after a corruption of the original name of the Levisa Fork, as it was originally written and spoken as the "Louisa Fork." An 1856 map still shows the river under the name "Louisa." Virginia, Carolina and other English colonial-linked settlement attempts began as early as 1790 but did not take hold until 1818. Louisa became the county seat in 1822 and a city in 1823.
