What drives Castroville’s History grade

On its age, its old homes and the National Register, Castroville is more historic than 33% of U.S. towns, #303 of 847 in California. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

California towns of 2,500+ (847)Ahead of 64%

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 Castroville’s 1.5 sits above most of its state (78% of California towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from C− to B−. The pre-1940 share (±2.4 points) is firm at this size. Two sources give 1863.

An intelligent observer wrote as follows, after a brief visit to this town" " The first introduction to Castroville, which is situated about a half mile from the railroad depot, is not prepossessing, since only small cottages, scattered here and there, wildly, yet in abundance, are met with; but upon entering it, one can see signs of life, business and thrift, and can forget the first impressions in the realization of the fact that there aresubstantial stores and residences, pretty gardens and plenty of trees.
