How fast is car insurance getting more expensive?

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

Car insurance prices changed by -5% in the 12 months to September 2026 (a minus sign means they fell). Their fastest rise since 1976 came in April 2024, when prices were 22.6% higher than in April 2023. Each point compares a month with the same month a year earlier. BLS priced car insurance only every few months before 1970, so the chart starts in 1971. BLS collected no prices in October 2025 and published none for car insurance in November 2025, so those months and the same months of 2026 are missing.

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 3 · World

How fast has the world come online?

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

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?

Chart 3 of 3 · Wealth

How is U.S. household wealth divided?

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

At the end of June 2026, the wealthiest 1% of U.S. households held 32.5% of all household wealth, the next 9% held 36.4%, the next 40% held 28.8% and the bottom 50% held 2.3%. In 1989 the shares were 22.8%, 38.0%, 35.7% and 3.5%. Wealth here is net worth: what households own (homes, stocks and mutual funds, pensions and retirement accounts, private businesses, cars and other belongings, bank deposits) minus what they owe (mortgages, credit cards, student and car loans). The Fed estimates each quarter by combining its Financial Accounts with its Survey of Consumer Finances, taken every three years, so the newest quarters are estimates that get revised.

How to read this chart

Each bar is one group of U.S. households' share of all household wealth, so the four bars add up to 100%. The groups are different sizes: the top 1% is one household in every hundred, while the bottom 50% is half of all households. Compare each group's share of wealth with its share of households.

Questions to discuss

  1. Which group holds the largest share of wealth? Is it the group with the most households?
  2. If wealth were split evenly, what share would the bottom 50% hold? How far is the chart from that?
  3. The takeaway gives the 1989 shares too. Which groups gained a share since then, and which lost one?
