Chart 1 of 2 · Crime
Is violent crime in the U.S. going up or down?
The interactive chart needs JavaScript. The numbers are on the chart's page.
Down, over the long run. Police reported about 329 violent crimes per 100,000 people in 2025, about 59% below the 1991 peak of about 798, and the lowest since at least 1985. The rate rose in 2020 and 2022, then fell in 2023, 2024 and 2025. In 2021 the FBI stopped taking its old summary reports and accepted only its newer, more detailed system (NIBRS); many police departments hadn't switched yet, so agencies covering only about 77% of Americans reported, against 88 to 98% in other years, and 2021's number is less certain. Rates count only the agencies that reported, so they differ a little from the FBI's national estimates, and the FBI widened its definition of rape in 2013.
How to read this chart
Each point is the number of violent crimes police reported for every 100,000 Americans that year. The line starts at zero, so its height shows the true size. In 2021 the FBI changed how it collects reports and fewer police departments sent numbers, so that year is less certain than the others.
Questions to discuss
- Find the year with the highest rate. About how much lower is the rate in the latest year?
- Many people say they think crime is rising. How could that belief and this chart both seem true to different people?
- Why might a change in how crimes are counted, like the one in 2021, make one year hard to compare with the rest?

What is the typical household income in each state?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In the Census Bureau's 5-year survey ending in 2024, the typical household in District of Columbia earned $109,870 a year, the most, followed by Massachusetts ($103,960) and Maryland ($103,678). Mississippi was lowest at $56,447, and the U.S. median was $80,734. These are 5-year estimates in 2024 dollars, each with a margin of error.
How to read this chart
Each bar is the median household income in a state: half of households earn more and half earn less. The dashed line is the whole U.S., for comparison. These are survey estimates, and each has a margin of error: the true value is likely within that range, so states with overlapping ranges may not really differ.
Questions to discuss
- Find your state. Is it above or below the U.S. median, and by about how much?
- Why do statisticians often use the median instead of the average (mean) for income?
- Housing and groceries cost more in some states. What would you need to know to compare what these incomes can buy?
