HistoryA character grade: shown, never part of Elwood’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 Elwood’s 5.0 sits above most of its state (75% of Illinois towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B. The pre-1940 share is a Census survey estimate (±6.0 points). Two sources give 1854.

What stands out about Elwood’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Elwood was founded in 1854 and incorporated as a village in 1869. The completion of the Joliet–Bloomington railroad, now part of the Union Pacific system, played a major role in the founding of Elwood. By 1900, Elwood was a small farming community with a population of about 400.
In the late 1930s, the federal government acquired nearby land for military training and weapons production, on which site the Joliet Arsenal was built and commenced operation in 1940. Arsenal construction played an important role in the development of Elwood and brought about 175 people into the area. In 1942, a massive explosion at the arsenal killed 42 workers and caused widespread damage.
