What drives San Gabriel’s History grade

On its age, its old homes and the National Register, San Gabriel is more historic than 90% of U.S. towns, #7 of 847 in California. All 3 inputs are above most U.S. towns; its age ranks highest and its share of homes from before 1940 lowest.

California towns of 2,500+ (847)#7 of 847

Few California towns list much on the Register (a typical California town has 0.0 per 10,000 residents, the U.S. 2.4), so San Gabriel’s 0.8 sits above most of its state (74% of California towns have fewer) while its 3 listings outnumber those of 65% 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 (±2.1 points) is firm at this size. Two sources give 1771.

The story

How San Gabriel came to be

From Wikipedia’s history of San Gabriel.

Read it all →

Prior to the arrival of the Spanish to Alta California, the area that is San Gabriel were inhabited by the Tongva, whom the Spanish called the Gabrieleño. The Tongva village of Shevaanga was located at the original site of Mission San Gabriel, before being moved to the site of another village, Toviscanga, in 1776 after being destroyed by a flood. These villages were part of an extensive trade network and were interconnected by a series of trails.
