The hazards accounting for most of this area's expected annual loss are inland flooding, earthquake and heat wave, with inland flooding alone responsible for 75% of it. Heat wave is independently rated low or minimal nationally, so this describes how the loss is composed, not how large that hazard is.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA publishes at county level. City values are the population-weighted mean of the counties the city overlaps, using AreaProfile place-to-county land-area weights. FEMA does not endorse this presentation.

North Plainfield's police department reported 129 violent offenses per 100,000 residents, near the middle of places with a department reporting. Property crime runs at 1,211.

Union County records 1.7 homicide deaths per 100,000 residents a year, lower than most counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 3.3 per 100,000 — more than the homicide rate, since the figure counts suicides and accidents as well as homicides.

Drug overdose deaths run at 16.1 per 100,000 residents in Union County.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides, so the firearm figure and the homicide figure above it count some of the same deaths twice over. They overlap and should not be added together.

Offenses are reported to the FBI by North Plainfield’s own police department and shown only where it reported every month of the year; a partial year is withheld rather than scaled up. Reported crime is what police recorded, which is not the same as what happened. Death rates are crude rates — deaths divided by population, not adjusted for age — except where a count was too small for the CDC to publish and it modeled the rate, which the card marks. They come from provisional death certificate records, published by the CDC by county and not below it. So they describe the county around North Plainfield (Union County) rather than North Plainfield itself. Neither is part of the Area Score. How to read crime rates and death rates.
