Preliminary Monthly Estimates

Monthly Preliminary Motor-Vehicle Fatality Estimates – June 2024

June motor-vehicle deaths down 1% from 2023

The number of miles driven in June 2024 decreased 0.4% compared to June 2023, but is still up 2.7% from 2022. The number of deaths for June 2024 is estimated to be 3,760. This preliminary estimate is down 1% from 2023 and down 5% from 2022. The decrease in the number of deaths combined with a decrease in miles driven results in a stable monthly mileage death rate compared to last June. The mileage death rate per 100 million vehicle miles driven for June 2024 is 1.32, compared to 1.32 in June 2023, 1.42 in June 2022, and 1.47 in June 2021.

How the National Safety Council Calculates Crash Fatality Estimates

The National Safety Council (NSC) collects preliminary motor-vehicle fatality estimates from data reporters in all 50 states and the District of Columbia. State data reporters generally work in state Department of Transportation offices and are often the same individuals responsible for providing data to the National Highway Traffic Safety Administration’s (NHTSA) Fatality Analysis Reporting System (FARS).

Each month, state data reporters provide a first estimate for the previous month’s fatalities and updated estimates for all previously reported months.

NSC maintains a three-year database of all state motor-vehicle fatality estimate reports. Using January as an example, the NSC database includes the January estimate first reported in February, as well as any updated January estimates reported in March, April, May, June, July, August, September, October, November, and December.

Fatality estimates tend to mature over the course of the year. Numbers often increase as fatalities are confirmed. Because of the maturation of the data, NSC calculates year-to-year percent change estimates by comparing monthly motor-vehicle estimates of comparable maturity.

To calculate national fatality estimates, percent change estimates are multiplied by the most recently available final motor-vehicle fatality estimates reported by the National Center for Health Statistics (NCHS). Therefore, NSC estimates reflect the NCHS definition of motor-vehicle fatalities as both traffic and non-traffic deaths that occur within a year of the
incident. Since NHTSA counts only traffic deaths that occur within 30 days of the incident, NSC motor-vehicle fatality estimates are not comparable to NHTSA figures.

All state level data are displayed as reported by each state. All fatality estimates are preliminary. To ensure proper comparisons, 2023 state fatality estimates are preliminary figures covering the same reporting period as those for 2024. In other words, preliminary 2024 estimates are compared to preliminary 2023 and 2022 estimates, even if updated estimates are available.
