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
- In one sentence of your own, what does this chart show?
- Find the biggest change or difference in the chart. What might explain it?
- Who collected these numbers, and how recent are they? What else would you want to know before drawing a conclusion?

What is the unemployment rate in each country?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In 2025, 4.2% of workers in the United States were unemployed, against 4.8% worldwide; the highest rate was 34.2% in Eswatini, and the lowest 0.1%, in Qatar. Search 182 countries and territories. These are the International Labour Organization's estimates, which count people without work who are looking for it and fill gaps where a country runs no regular survey, so they can differ from a country's own figures.
How to read this chart
Each bar is the share of a country's workers who have no job and are looking for one, estimated by the International Labour Organization. The dashed line is the world. People who aren't looking for work, such as students and retirees, aren't counted as unemployed at all.
Questions to discuss
- Is the United States above or below the world rate, and by about how many percentage points?
- A country can have low unemployment while many people earn very little. How is that possible?
- Why would someone who has given up looking for work not count as unemployed? Does that make the number more or less useful?

How much has the US warmed since 1895?
The interactive chart needs JavaScript. The numbers are on the chart's page.
The contiguous US averaged 54.6°F in 2025. The warmest year since records began in 1895 was 2024, at 55.5°F. Through 2025, the dashed trend line, the straight line that best fits every year, rose about 0.18°F a decade, or 2.3°F since 1895, and warming had sped up to about 0.5°F a decade since 1970. Alaska and Hawaii aren't included.
How to read this chart
Each point is one year's average temperature across the lower 48 states, in degrees Fahrenheit. The axis doesn't start at zero, so a small rise looks steep: read the numbers on the axis, not the height of the line. The dashed line is the trend, the straight line that best fits every year; single years bounce above and below it.
Questions to discuss
- Find the warmest and coolest years on the chart. How many degrees apart are they?
- Why might one year be much cooler than the year before, even while the trend line keeps rising?
- The axis doesn't start at zero here, but bar charts always do. Why is that fair for temperatures but not for bars?
