Two hundred years ago, large parts of the world were ruled by a few European colonial powers, as the chart shows.
Since then, people in many countries have fought against colonial rule.
A first wave of countries gained independence in the 19th century, particularly in the Americas.
However, most countries did not gain independence until the middle of the 20th century.

Over the last twenty years, plastic waste recycling has considerably increased worldwide, as the chart shows.
OECD countries in the European Union, India, and China have spearheaded this growth. By 2019, recycling rates were 12–13%. Non-OECD Asian countries and Latin America have also made headway, but more slowly.
The United States and the Middle East & North Africa region have seen more sluggish advances, with the US only managing to reach a 4.5% recycling rate by 2019, according to the OECD data.
Different regional strategies and capacities have led to markedly different outcomes in plastic waste management.

The “modal age at death” is the most common age at which people in a population die. The modal age at death for women in Japan in 2021 was 93. In France, it was 92.
This metric helps us understand trends in longevity at older ages. Unlike life expectancy, it is not affected by infant or child mortality.
You can see that over time, the figure has been rising steadily. In France in 1970, the modal age at death was 84 years for women, but now it is 8 years higher.
Large gains in longevity have occurred even among the elderly.

Data Insight
2,664 objects were launched into space in 2023. This figure breaks the record set the previous year.
The chart shows that US agencies and companies were responsible for launching 2,166 of these objects; that’s 81% of the global total.
Within American launches, 1,935 objects — 73% of the global total — belonged to Starlink, the constellation of satellites operated by the aerospace company SpaceX.
The rapid growth of the global satellite constellation has the power to help expand Internet connectivity, but also contributes to increasing concerns regarding space debris and the congestion of Earth’s orbital environment.

In 2000, less than 10% of the population in Indonesia had access to clean cooking fuels. This is now over 80%, as the chart shows.
Clean cooking fuels are those that, when burned, emit less than the World Health Organization's recommended amounts of air pollutants. They reduce the burden of air pollution — and its health impacts — for the households that use them.
In 2007, the Indonesian government launched a national program to move from kerosene cooking fuels to liquefied petroleum gas.
This shift has greatly reduced particulate pollution and improved health outcomes. Death rates from indoor air pollution have fallen steeply.

Data Insight
In 1981, 97% of people in the Chinese countryside lived in extreme poverty. Even in cities, it was more than 70%.
Since then, large economic growth has made it possible for hundreds of millions of people in China to leave extreme poverty behind, first in cities and then in the countryside.
By 2020, the share of people living in extreme poverty in both urban and rural areas was below 1%.

Solar and wind have surpassed coal as a source of electricity generation in a number of countries, as the chart shows. This marks a substantial shift towards more sustainable sources of energy.
Even in the United States, the world’s third-largest producer of coal electricity, the gap between solar and wind power, and coal is now very small. The adoption of clean energy is accelerating.

People in richer countries tend to live much longer than those in poorer countries.
We can see this in the cross-country life expectancy statistics shown on the chart. In Japan, life expectancy at birth is about 85 years, while in Chad and Nigeria, life expectancy is about 52 years — a gap of over three decades.

Pacemakers are crucial medical devices for people with heart disorders and irregular heartbeats. They provide a steady heart rhythm and help the heart pump blood effectively to the rest of the body.
The chart shows that there are large differences in the rates of pacemaker implantations across countries.
In France and Sweden, over 1,000 per million people each year receive pacemaker implantations. In Egypt and Turkey, that figure is less than 150.
