History grade
What drives Liberty’s History grade

HistoryA character grade: shown, never part of Liberty’s overall grade.
Indiana towns list more on the Register than most of the country (a typical Indiana town has 7.9 per 10,000 residents, the U.S. 2.4), so Liberty’s 102 sits above most of its state (81% of Indiana towns have fewer) while its 21 historic buildings outnumber those of 80% of U.S. towns.
