Chart 1 of 3 · Interest rates

What does the Treasury yield curve look like today?

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

On November 5, 2026, a 3-month Treasury bill paid 4.17% a year, a 2-year note 4.46%, a 10-year note 4.84% and a 30-year bond 5.25%. Longer loans to the government paid more than short ones, the usual upward slope. When short-term rates are higher than long-term ones the curve is called inverted. Each bar is Treasury's par yield for that length of loan at the close of the day.

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 · Income and poverty

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

  1. Find your state. Is it above or below the U.S. median, and by about how much?
  2. Why do statisticians often use the median instead of the average (mean) for income?
  3. Housing and groceries cost more in some states. What would you need to know to compare what these incomes can buy?

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?
