What do people die from? What is the life expectancy in different countries, and how has this changed over time? How do health outcomes and systems vary across the world?
Find answers to these questions and many more in our new Global Health Data Explorer.
The explorer covers the following high-level areas, with many indicators within each area and data from multiple sources to compare:
The World Bank's definition of extreme poverty was recently updated - from $1.90 to $2.15 a day.
The key point is that the change from $1.90 to $2.15 a day doesn't imply shifting goalposts. It reflects a change in units - from 2011 to 2017 international-$.
Accordingly, on a global level extreme poverty estimates look similar on both bases. But for individual countries, there can be significant differences between the old and updated methodology.
To understand these changes, we need to understand what an international-$ is and the two adjustments it makes: for inflation and for differences in the cost of living between countries.
In this article, we explain what an international-$ is, what's going on with this change, and what it means for our understanding of global poverty.
The world has made progress in eliminating biological and chemical weapons - organisms, toxins, and chemicals used to cause death or harm through their poisonous properties.
Because they can kill or injure large numbers of people and cause environmental damage, they are considered weapons of mass destruction.
Fewer countries use, possess, and pursue these weapons than in the past.
In our new page on Biological and Chemical Weapons, we visualize countries' current and historical use of these weapons.
Habitat loss is the largest threat to biodiversity, and most of this loss is driven by agriculture.
On our current path, researchers project that we'd need an extra 3.4 million square kilometers of cropland by 2050 - an area the size of India and Germany combined. This would destroy habitats for hundreds if not thousands of species of mammals, birds, and amphibians.
But we have opportunities to avoid this. In this article from September 2021, we describe how improving crop yields - particularly across Sub-Saharan Africa - would have a massive impact on preserving wildlife. Changing what we eat and how much we waste would also help.
If we combine these actions, the world would actually need less cropland than we use today. The loss of wild habitats across the world would be minimal. It is possible to both feed 10 billion people a healthy, nutritious diet and increase the space for the world's wildlife.
The mission of Our World in Data is to make data and research on the world's largest problems understandable and accessible for everyone.
