What drives California’s History grade
On its age, its old homes and the National Register, California is more historic than 90% of U.S. towns, #178 of 1,035 in Pennsylvania. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.
A
HistoryA character grade: shown, never part of California’s overall grade.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so California’s 10.3 sits above most of its state (77% of Pennsylvania towns have fewer) while its 5 historic buildings outnumber those of 70% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A. The pre-1940 share is a Census survey estimate (±6.5 points). Two sources give 1849.

Upon its founding in 1849, name suggestions included Columbia and Sagamore. Because the town's founding coincided with the California Gold Rush, it was named California to symbolize growth and prosperity. Before there were mayors in California, there were burgesses, the first of whom was Solomon Sibbitt.
