Figures as of November 14, 2026, from each chart's current data.
Chart 1 of 1 · Road safety
The chart's answer: 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.
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?
Open question: answers will vary. Look for answers that use the chart's numbers and source.
