Chart 1 of 3 · Inflation

How fast are US prices rising?

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

The inflation rate was 3.7% in September 2026: how much consumer prices changed from the same month a year earlier. Each point makes that comparison, back to 1914, the first year BLS can compare. Inflation peaked at 23.7% in June 1920 and at 14.8% in March 1980; the 9.1% of June 2022 was the highest since 1981. Prices fell as fast as 15.8% a year in 1921 and 10.7% in 1932. BLS collected no prices in October 2025, during a lapse in federal funding, so that month and October 2026 are missing.

How to read this chart

Each point compares consumer prices in a month with the same month a year earlier. A value of 3 means things cost about 3% more than a year before; below zero means prices fell. The chart shows how fast prices change, not how high they are.

Questions to discuss

  1. Find two times when inflation was highest. What was happening in the country then?
  2. If inflation falls from 8% to 3%, are prices going down, or just rising more slowly?
  3. Find a stretch when the line is below zero. Why might falling prices be bad news for workers and businesses?

Chart 2 of 3 · 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?

Chart 3 of 3 · Baby names

How many babies were given your name each year since 1880?

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

Type any name to see how many U.S. babies were given it each year since 1880, for girls or boys. Emma, shown first, went from 2,003 girls in 1880 down to 414 in 1976, then back up to a peak of 22,719 in 2003; in 2025 it was 12,754. The counts come from Social Security card applications, so the early years undercount everyone. A year with fewer than 5 babies of a name shows as 0, because Social Security leaves those names out for privacy.

How to read this chart

Each point is the number of U.S. babies given a name in one year, from Social Security card applications. Type any name to see its line, for girls or boys. These are counts, not shares, and far more babies are born today than in 1880, so a count can grow just because the country did.

Questions to discuss

  1. Look up your own name or a friend's. When was it most popular, and what might explain that?
  2. Why are counts from the 1880s lower than counts today, even for names that were very popular then?
  3. How could you change these counts to fairly compare a name's popularity in 1900 with today?
