Which months have the most cancelled flights?

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

In the 12 months from September 2025 to August 2026, U.S. airlines cancelled the largest share of scheduled flights in January 2026, 4.7%, and the smallest in September 2025, 0.5%. In November 2025 the government shutdown led the FAA to order flight cuts. Each bar is one month, not an average over many years.

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?

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

  1. Is the United States above or below the world rate, and by about how many percentage points?
  2. A country can have low unemployment while many people earn very little. How is that possible?
  3. Why would someone who has given up looking for work not count as unemployed? Does that make the number more or less useful?
