History grade

On its age, its old homes and the National Register, Pueblo is more historic than 74% of U.S. towns, #14 of 159 in Colorado. Its National Register listings hold the grade up; its age pulls it down.
B+
HistoryA character grade: shown, never part of Pueblo’s overall grade.
Among the 400 U.S. cities of 100,000 or more, Pueblo ranks #152 on History.
Few Colorado towns list much on the Register (a typical Colorado town has 1.1 per 10,000 residents, the U.S. 2.4), so Pueblo’s 13.6 sits above most of its state (75% of Colorado towns have fewer) while its 152 historic buildings outnumber those of 92% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share (±1.4 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1885 falls in the same era, so the grade doesn’t depend on which one is used.

From 1050 to 1450, the area that is now Pueblo was first inhabited by Paleo-Indians and Archaic peoples, as well as people of the Apishapa culture. By 1500, the Ute hunter-gatherers inhabited the region, who hunted in the mountains during the summer and wintered in warmer areas, such as modern-day Pueblo, during the winter. In 1521, Spain assumed control of the land, however, very little settlement or occupation ever occurred. By the time of the 17th century, the Ute acquired horses from the Spanish allowing them to hunt bison on the plains. The Ute bands of the Pueblo area were the Tabaguache and the Muache. Along the eastern Arkansas River, the Jicarilla Apache lived in villages and hunted bison, and grew corn, beans, and squash.
