Chart 1 of 2 · Commuting

How long is the commute to work in your county?

The interactive chart needs JavaScript. The numbers are on the chart's page.

Search any of the 3,143 U.S. counties. In the Census Bureau's five-year survey ending in 2024, workers living in Glascock County, Georgia had the longest average one-way commute, 49.6 minutes, and those in Skagway Municipality, Alaska the shortest, 4.9. People who work from home are not counted, and small counties' estimates have wide margins of error.

Questions to discuss

  1. In one sentence of your own, what does this chart show?
  2. Find the biggest change or difference in the chart. What might explain it?
  3. Who collected these numbers, and how recent are they? What else would you want to know before drawing a conclusion?

Chart 2 of 2 · Crime

Which big U.S. cities have the most violent crime?

The interactive chart needs JavaScript. The numbers are on the chart's page.

In 2025, Memphis, TN had the highest violent crime rate of the 89 biggest U.S. cities whose police reported a full year to the FBI, about 1,853 per 100,000 people, followed by Detroit, MI (1,654) and Oakland, CA (1,475). Irvine, CA (79) and Virginia Beach, VA (101) had the lowest; the U.S. rate was about 330. Violent crime is murder, rape, robbery and aggravated assault. In 2025 the police in New Orleans, Orlando and St. Petersburg, Florida, didn't report a full year of crimes, so they are left out. Each rate is per person the department serves, and a few, such as Las Vegas, Honolulu, Jacksonville and Louisville, serve their whole county. A city's rate also depends on where its borders fall, so compare cities with care.

How to read this chart

Each bar is one big city's violent crimes reported to the FBI in a year (murder, rape, robbery and aggravated assault) for every 100,000 people its police department serves. The dashed line is the rate for the whole U.S. Dividing by population makes big and small cities fair to compare, but a city's rate also depends on where its borders fall.

Questions to discuss

  1. Find the city with the highest rate and the one with the lowest. About how many times higher is the top rate?
  2. Some departments police a whole county, suburbs included. How could that change a city's rate compared with one that covers only its downtown?
  3. These are crimes reported to police. What kinds of crime might never show up in these numbers, and why?
