What these numbers mean
Each card names its data year. Historical values are estimates and trends are not personal predictions.
World population
In 1990, about 5.33 billion people lived on Earth. The value comes from the UN annual series; the latest comparison uses 2024.
Life expectancy
This is life expectancy at birth under the mortality conditions of that year—not a prediction of one person's lifespan.
People online
This counts people who used the internet within the previous three months. Early birth years use the nearest available estimate.
Forest area
Area includes naturally regenerating and planted forest. A larger area does not necessarily mean biodiversity or forest quality recovered.
