Seneca, Illinois has about 2,450 people. That count is a 2020–2024 Census average, not a headcount from one day.

A typical home is worth about $227,500.

HUD's fair-market rent for a 2-bedroom in LaSalle County is $1,052 a month. That is the county number, not an apartment listing in Seneca. It runs from October 2026 through September 2027.

Illinois's prices sit at 100.0 when the U.S. average is 100. This place is not in a metro area with its own index, so this is the state number from BEA for 2024.

Illinois taxes wages. A typical combined sales tax is 9.0% as of January 1, 2026. That mix is statewide, not Seneca's exact store tax.

In July 2026, a typical Illinois home paid 19.22¢ per kilowatt-hour. That is a state average from EIA, not Seneca's bill.

EIA did not publish a 2025 all-grades gas price for Illinois in the table we use.
