What drives Princeton’s History grade
On its age, its old homes and the National Register, Princeton is more historic than 93% of U.S. towns, #48 of 768 in Illinois. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.

Greenfield was the name proposed for the new town, as that was the name of the post-office for the settlement, but some thought Princeton more appropriate, as the town site was much like Old Princeton in New Jersey, being high and sightly.
