Drive 10 miles in any direction and you reach 7 towns with grades of their own. South Valley Stream has no police department of its own: it’s an unincorporated community (a census-designated place) in Nassau County. The Nassau County Sheriff’s Office reports to the FBI for the parts of the county without police of their own, so there are no figures for South Valley Stream alone, and no Safety Grade. The nearest town with a Safety Grade is Rockville Centre, 4 miles away, graded A.

One person died in crashes on South Valley Stream’s roads in 2019–2023
South Valley Stream had 1 fatal crash in five years, in which one person died.
That is about what is typical for New York towns of 5,000–25,000 people: at their median rate (5.9 deaths per 100,000 residents a year), a town of South Valley Stream’s size would see about 2 in five years. With numbers this small, a death or two either way changes the picture, so South Valley Stream’s own rate (3.1) 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.
- A county agency covers a wide area. Its totals mix many communities, so they say little about any one of them.
- Gaps are real gaps. A missing year means the department didn’t report a full year, not that nothing happened.
