How much does a dozen eggs cost in the US?

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

A dozen grade A large eggs averaged $2.27 in September 2026. The record so far is $6.23 in March 2025; prices spiked in 2023 and 2025 when bird flu cut the number of laying hens. Prices are BLS averages across US cities since 1980, when this series begins, in dollars of the day, not adjusted for inflation. October 2025 is missing because a lapse in federal funding stopped data collection.

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 · 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?

Chart 3 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?
