Chart 1 of 2 · Crime
Which states have the highest reported rape rates?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In 2025 Alaska had the highest rate of rapes reported to police, about 122 per 100,000 people, followed by Arkansas (72) and Montana (64). Connecticut (16), New Jersey (17) and Delaware (19) had the lowest; the U.S. rate was about 37. Many rapes are never reported, so these rates show reports, not how often rape happens, and they use the FBI's broader definition adopted in 2013. Rates count only the police agencies that reported to the FBI; in a few states, such as Florida and Mississippi, those cover only about 80 to 85% of residents. Since 2021, when the FBI began taking only its newer NIBRS reports, state rates don't line up exactly with earlier years.

Are U.S. roads getting safer per mile driven?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In 2024 there were 1.19 deaths for every 100 million miles driven, down from 3.35 in 1980. The lowest rate was 1.08 in 2014; it jumped to 1.34 in 2020, when people drove less but deaths rose. Miles driven are the Federal Highway Administration's estimates.
How to read this chart
Each point is the number of people killed in traffic crashes for every 100 million miles Americans drove that year. Dividing by miles driven turns a count into a rate, so years when people drove more or less can be compared fairly.
Questions to discuss
- About what fraction of the 1980 rate is the rate in the latest year?
- In 2020 people drove less, but the rate went up. What could explain that?
- Why is deaths per mile a fairer way to compare years than the total number of deaths?
