NJ Traffic Crash Data

The first 5 plots below come from NJ State Police fatal crash data (2008-present). It's generally current to the previous day.

Below that are plots of NJ DOT raw crash data, which includes 6MM property-damage, injury, and fatal crashes from 2001-2021. It's a richer dataset, but less up to date.

I'm working on mapping the NJDOT data; here are 5 years (2017-2021) of fatal and injury crashes in Hudson County:

NJ Traffic Deaths per Year

2021 and 2022 were the worst years in the NJSP record (since 2008), with 697 and 689 deaths, resp.

As of Dec 5, 2023 is on pace for 596.

Victim types have been published since 2020; prior years are shown as "Unknown".

NJ Traffic Deaths per Year

Some data arrives weeks or months after the fact, so current year numbers are especially subject to change.

NJ Traffic Deaths vs. Homicides

Traffic crashes kill 1.5-2x as many people as homicides in NJ.

Homicide data comes from NJ State Police and Disaster Center.

NJ DOT Raw Crash Data

NJ DOT publishes raw crash data, including property-damage, injury, and fatal crashes, going back to 2001 (≈6MM records).

The data currently ends in 2020, after a drop in all types of crashes due to COVID, and just before a spike in all crash types in 2021 and 2022 (based on the NJSP data above, and other sources). 2021 data should land in early 2023.
