On its age, its old homes and the National Register, Berkeley is more historic than 42% of U.S. towns, #453 of 768 in Illinois. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.

HistoryA character grade: shown, never part of Berkeley’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 Berkeley’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 two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share is a Census survey estimate (±9.4 points).

What stands out about Berkeley’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Farmers, mostly of German and Dutch heritage, began to settle in the region that would become Berkeley around 1835. The Dutch sought to be truck farmers, dwelling on farms spanning from 40 to 160 acres, whereas the Germans conducted general farming. In 1848, a small group of farm families founded Sunnyside, a one-room school. Sunnyside Elementary School is still in operation today, however it is now located in a bigger and newer structure.
Farmland was provided for what is now known as Old Settler's Cemetery a short distance west on St. Charles Road (which was finished in 1836). Many of the area's earliest settlers remain buried there.
Berkeley is more historic than 42% of U.S. towns, #453 of 768 in Illinois. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
