What drives Indianapolis’ History grade

On its age, its old homes and the National Register, Indianapolis is more historic than 89% of U.S. towns, #157 of 593 in Indiana State. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.

A
HistoryA character grade: shown, never part of Indianapolis’ overall grade.
All U.S. towns we grade (21,289)Ahead of 89%
NewerOlder
Indiana State towns of 2,500+ (593)Ahead of 74%

Among the 400 U.S. cities of 100,000 or more, Indianapolis ranks #73 on History.

Indiana State towns list more on the Register than most of the country (a typical Indiana State town has 7.9 per 10,000 residents, the U.S. 2.4), so Indianapolis’ 140 sits above most of its state (84% of Indiana State towns have fewer) while its 12,517 historic buildings outnumber those of 100% 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 (±0.4 points) is firm at this size. Two sources give 1821.

The story

How Indianapolis came to be

From Wikipedia’s history of Indianapolis.

Read it all →

In 1816, the year Indiana gained statehood, U.S. Congress designated four sections of land in central Indiana as the future seat of state government, contingent on tribal removal. Under the Treaty of St. Mary's (1818), the Delaware and Miami nations relinquished title to these designated lands, with agreement to vacate by 1821. This tract of land, which was called the New Purchase, included the site selected for the new state capital in 1820. The indigenous people of the land prior to systematic removal are the Miami Nation of Indiana (Miami Nation of Oklahoma) and Indianapolis makes up part of Cession 99; the primary treaty between the indigenous population and the United States was the Treaty of St. Mary's in 1818.
