Why is food recalled?

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

The most common reason is “allergen not on the label”: 2,501 of the 7,081 food recalls the FDA classified from 2013 through 2025, about 35%. Listeria (847) and Salmonella (757) come next. Chartly grouped FDA's written reasons by their key words; each recall counts once, under its first matching reason. Meat, poultry and most egg products are USDA's to recall and aren't included.

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 · World

How fast has the world come online?

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

73.6% of the world's people used the internet in 2025, up from 15.6% in 2005, the first year the World Bank gives a world figure. It counts people who used the internet at least once in the previous three months. The world figures are estimates by the International Telecommunication Union.

How to read this chart

Each point is the share of the world's people who used the internet at least once in the previous three months, as estimated by the International Telecommunication Union. The axis starts at zero, so the height shows the true share. The steeper the line, the faster people were coming online.

Questions to discuss

  1. About what share of the world was online in the first year on the chart, and in the latest year?
  2. Did the share grow faster in some years than others? What could have sped it up?
  3. Using the internet once in three months counts here. What does this number leave out about how people get online?

Chart 3 of 3 · 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?
