How often do ranked college football teams lose to unranked teams?

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

Unranked FBS teams won 19.7% of their games against AP Top 25 teams in 2025. The share has ranged from 4.5% in 1998 to 25.9% in 2007, and has usually been higher since 2000 than in the 1990s. A team counts as ranked if it was in the AP poll that stood before the game; bowl games count, and games against lower-division (FCS) teams don't. The chart starts in 1989, when the AP poll began ranking 25 teams every week.

Chart 2 of 2 · World

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?
