We have a new Economic Inequality topic page— Public attention to economic inequality has grown a lot over the last twenty years. At the same time, the available data has greatly improved too: it now covers many more countries and longer time periods, and is more comparable and accessible than ever
Dot-and-line chart of monthly income or consumption at the 90th and 10th percentiles for selected countries, where it illustrates large gaps between the richest and poorest 10%. It shows the richest 10% in the United States at about $5,508 per person per month versus $789 for the poorest 10%, and smaller absolute amounts but clear gaps in Brazil (about $1,626 vs $161), Vietnam (about $875 vs $177) and Madagascar (about $156 vs $32).

How has the world's population changed over the last 12,000 years? What do projections tell us about the rest of this century? We've refreshed four of our most popular static charts that show you answers to these questions, updating them with the latest data from the UN. 🧵
The size of the world population over the long-run.

A line chart of world population from 10,000 BCE to present with a short projected extension into the 21st century. It shows a very slow, nearly flat increase for millennia, a small bump around 2,000 years ago, and a rapid exponential rise after about 1800 leading to roughly 8 billion in 2022. Key labeled milestones: about 4 million in 10,000 BCE; 595 million in 1700; 983 million in 1800; 1.6 billion in 1900; 2 billion in 1927; 3 billion in 1960; 4 billion in 1975; 5 billion in 1987; 6 billion in 1998; 7 billion in 2010; 8 billion in 2022. The chart includes a UN Population Division projection that reaches 9 billion in 2037, 10 billion in 2061, and a peak of about 10.3 billion in 2084 before declining. Annotations note that average growth from 10,000 BCE to 1700 was about 0.04 percent per year and that the mid-14th century Black Death killed between a quarter and a half of the population of Europe.
