How has the world's population grown since 1960?

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

The world had 8.22 billion people in 2025, about 2.7 times the 3.02 billion of 1960. It passed 8 billion in 2023. Figures are mid-year estimates from the United Nations, which revises them as new censuses come in.

How to read this chart

Each point is the number of people alive in the world in the middle of that year, estimated by the United Nations. The axis starts at zero, so the height of the line shows the true size. Look at how steep the line is to see how fast the population grew.

Questions to discuss

  1. Judging from the chart, about how many years did it take the world to add its most recent billion people?
  2. Is the line getting steeper or flatter in recent years? What does that tell you about the growth rate?
  3. These numbers are estimates that the UN revises. Why is it hard to count every person on Earth?

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?
