A line chart showing productivity, defined as gross domestic product (GDP) per hour of work, for a selection of 10 countries from 1950 to 2023. The data is adjusted for inflation and differences in living costs between countries. At the top of the chart is Denmark, with a productivity of 88.7 $ per hour. At the bottom is Ethiopia, at 4.5 $ per hour. The data source is the Penn World Table (2025). The chart is licensed CC BY to Our World in Data.

A chart showing how the share of the global population between different poverty lines has changed since 1990. Extreme poverty (defined as being below the International Poverty Line of $3 a day) has decreased from 43% in 1990 to 10% today. Poverty has also decreased at other thresholds. The data source is the World Bank. The chart is licensed CC BY to Our World in Data.

To track progress towards ending extreme poverty by 2030, the United Nations relies on the World Bank to estimate the share of people living below a certain threshold, called the International Poverty Line (IPL).

A line chart showing the global number of people living in extreme poverty. Extreme poverty is defined as living below the International Poverty Line (IPL), which is $2.15 per day in 2017 prices (shown as a red line on the chart) and $3 per day in 2021 prices (shown as a blue line).

125 million people who would not have been counted as extremely poor before June 2025 (when the IPL was raised to $3 per day) are now included.

This data is adjusted for inflation and for differences in living costs between countries. The data source is the World Bank (2024 and 2025). The chart is CC BY Our World in Data.

OWID maps recently got a revamp. A key improvement: it’s now much easier to zoom and explore on mobile. Select a country or region, then pinch and pan to dive in 🪄

We didn't see them as the pictures, but it was cool to "develop" them in the phone.

It's very cool to see how they show up in the sky. We were tracking with the Aurora app, but we were unlucky the first day (cloudy) and on the second day they showed up. They were not in their biggest intensity, but we could see pale greens and different shapes.

I look at democracy data for a living, and the US indeed seems to be in a constitutional crisis right now - but this move by Polity makes me take it less seriously, not more.

Here’s why:

A world map illustrates the share of the population living in multidimensional poverty, defined as deprivation in health, education, and living standards. The map employs varying shades of purple and pink to indicate the percentage of the population affected by multidimensional poverty in different countries.

In many countries, more than half of the population faces poverty in multiple dimensions.🧵

Miremos los datos de los "mejores puntajes" con una perspectiva diferente al tradicional "ranking"

Si ordenamos de menor a mayor a todos los estudiantes recién egresados que rindieron la prueba de Lenguaje + Matemática según su puntaje y los agrupamos en 10 grupos, tenemos 10 deciles.

A chart in three parts showing data on child mortality to make the points that "The world is awful. The world is much better. The world can be much better. All three statements are true at the same time."

The world is awful. The world is much better. The world can be much better.

All three statements are true at the same time. Understanding this is key to solving big global problems.

We believe data & research can help us understand both the problems we face & the progress that’s possible. 🧵
