What drives Wood River’s History grade
On its age, its old homes and the National Register, Wood River is more historic than 33% of U.S. towns, #527 of 768 in Illinois. Its share of homes from before 1940 holds the grade up; its age pulls it down.
C
HistoryA character grade: shown, never part of Wood River’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 Wood River’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 B. The pre-1940 share is a Census survey estimate (±4.3 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1908 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Wood River’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Wood River developed as a company town around an oil refinery. The Standard Oil Company broke ground on a refinery near the site in April 1907, and the plant began operating at the start of 1908. The community was founded in 1907; it merged with the neighboring settlement of East Wood River in 1910 and with Benbow City in 1917, and was chartered as a city in 1923.
