How has the U.S. murder rate changed since 1985?

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

Police reported about 4.3 murders per 100,000 people in 2025, the lowest since at least 1985, and down from a peak of about 10.3 in 1991. The rate jumped from 5.2 in 2019 to 6.8 in 2020, the biggest one-year rise from 1985 to 2025, then fell back by 2024. 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. Murder here means murder and nonnegligent manslaughter as police report it.

Questions to discuss

73.6% of the world's people used the internet in 2025, up from 15.6% in 2005, the first year the World Bank gives a world figure. It counts people who used the internet at least once in the previous three months. The world figures are estimates by the International Telecommunication Union.

How to read this chart

Each point is the share of the world's people who used the internet at least once in the previous three months, as estimated by the International Telecommunication Union. The axis starts at zero, so the height shows the true share. The steeper the line, the faster people were coming online.

Questions to discuss

  1. About what share of the world was online in the first year on the chart, and in the latest year?
  2. Did the share grow faster in some years than others? What could have sped it up?
  3. Using the internet once in three months counts here. What does this number leave out about how people get online?

How to read this chart

Each bar is the share of a country's people who used the internet in the previous three months. The dashed line is the whole world. The chart opens on the top and bottom of the ranking; search for a country to find its bar among the rest.

Questions to discuss

  1. Find the United States and one country on another continent. How far apart are their shares?
  2. What do the countries at the bottom of the ranking have in common? What might keep people there offline?
  3. The world figure is closer to the bottom than many rich countries are to the top. Why might that be?
