What drives Oregon’s History grade
On its age, its old homes and the National Register, Oregon is more historic than 96% of U.S. towns, #22 of 768 in Illinois. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.
A+
HistoryA character grade: shown, never part of Oregon’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Oregon’s 125 sits above most of its state (95% of Illinois towns have fewer) while its 48 historic buildings outnumber those of 85% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±7.4 points). Two sources give 1833.

During all these years, however, notwithstanding Oregon and other towns had repeatedly voted aid, the company had accomplished nothing toward the construction of the road. The nearest railroad point to Oregon, the county seat, was at Franklin Grrove, Lee County, on the (Chicago & ]N'orthwestern Railroad, twelve miles away. The Ogle and Carroll County Railroad Company had a contract with the old Galena and Chicago Union Railroad Company by which a junction of the two roads was contemplated at Lane (now Rochelle), and this contract provided certain drawbacks on
