What drives Kirby’s History grade

On its age, its old homes and the National Register, Kirby is more historic than 3% of U.S. towns, #591 of 642 in Texas. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so Kirby’s 0.0 sits below most of its state (34% of Texas towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from D− to D. The pre-1940 share (±0.7 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1955.

How Kirby came to be

From Wikipedia’s history of Kirby.

Kirby was founded as an agricultural community by German immigrants in the early 1900s. Its name derived from the Kirby yard of the Southern Pacific Railroad that crossed through the town. In 1920, the population was around 18 people, made up of mostly farmers. At this time, German was a commonly spoken language.
