What drives Eagar’s History grade

On its age, its old homes and the National Register, Eagar is more historic than 38% of U.S. towns, #34 of 140 in Arizona. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.

Few Arizona towns list much on the Register (a typical Arizona town has 0.1 per 10,000 residents, the U.S. 2.4), so Eagar’s 72.5 sits above most of its state (91% of Arizona towns have fewer) while its 32 historic buildings outnumber those of 82% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from D to B. The pre-1940 share (±0.7 points) is firm at this size. Two sources give 1871.

The story

How Eagar came to be

From Wikipedia’s history of Eagar.

Read it all →

Brothers William Walter, John Thomas, and Joel Sixtus settled the area under the direction of The Mormon prophet Brigham Young. They each acquired 160 acres of land under the homestead act. Once they received the deeds to their properties, again under the direction of Brigham Young, they each subdivided their properties to sell at a discounted rate to other church members who were also settling the area.
