One person died in crashes on Rock Valley’s roads in 2019–2023
Rock Valley had 1 fatal crash in five years, in which one person died.
That is about what is typical for Iowa towns of 2,500–5,000 people: at their median rate (0.0 deaths per 100,000 residents a year), a town of Rock Valley’s size would see about 0 in five years. With numbers this small, a death or two either way changes the picture, so Rock Valley’s own rate (4.9) is context, not a ranking.
Deaths are counted where the crash happened, not where the people lived: a highway through town adds through-traffic deaths, and residents’ own risk on roads elsewhere isn’t here. Town rates sit below state and U.S. rates because a third of fatal crashes happen outside any town. Road safety is described here and is not part of the Safety Grade.

What this data can and can’t tell you
- It’s reported crime. Only incidents reported to and recorded by police appear here. Many crimes are never reported to police.
- One number for all of Rock Valley. A town-wide rate doesn’t show where incidents happen, and that can differ a lot from one part of town to another.
- Visitors count too. Incidents involving people who work, shop or visit are counted against Rock Valley’s residents, which raises the per-resident rate.
- Whose population. Rates use the FBI’s population for the department (4,012 in 2025); our figure for Rock Valley is 4,188 (2025 Census estimate).
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
