What drives Northbrook’s History grade

On its age, its old homes and the National Register, Northbrook is more historic than 11% of U.S. towns, #722 of 768 in Illinois. Its share of homes from before 1940 holds the grade up; its age pulls it down.

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 Northbrook’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

How sure. Graded on any two of the three inputs instead, the letter would range from D to C−. The pre-1940 share (±1.5 points) is firm at this size. Two sources give 1901.

Members of the Potawatomi tribe were the earliest recorded residents of the Northbrook area.

A German immigrant named Frederick Schermer donated a portion of the land he bought from Sherman to be used for the town's first railroad station, which was named after him.
