The Wikipedia community has built a tool that makes it possible to embed our interactive Our World in Data charts right in any Wikipedia page. I have always admired Wikipedia and all the people contributing to it. And I'm very happy that our work now can get used this way!

Right now I'm working on this timeline of wars over the last two centuries.

How has global poverty changed in our lifetimes? No matter what poverty line you choose, the share below it has declined globally.

Future population projections expect that fertility rates stop declining and roughly stabilize. This new NBER paper asks what evidence we have to expect this. It finds there is none. "Instead, where and when fertility has fallen low, it has tended to keep falling." nber.org/papers/w35824

This is a new paper, but it was exactly our motivation earlier this year when we built our Population Projection Simulation. It runs in your browser and that lets you explore what the future looks like when the assumed fertility rebound does not happen. ourworldindata.org/populatio…

If we think of AI as the next industrial revolution we should ask which chart like these we're likely to get.

Excited to share our new working paper: how much did the US standard of living really rise over the twentieth century — and when? With @bhwittenbrink Using 5.1 million Sears catalog listings, we build a quality-adjusted price index for consumer goods, 1900–1990. Two headline findings: growth was much larger than official statistics imply, and its peak came before WWII, not after. (1/9)

In a hotel room in northeast Nigeria, I opened a leading AI chatbot, turned my laptop toward a former Boko Haram commander, and asked if he'd used it. He nodded. "You type in the question… like 'How can I build a bomb?', and then it tells you how. It is like a human robot. We used it a lot." My new study on how the jihadist terrorist group Boko Haram uses frontier AI with @CamAISciPolicy, covered today in @nytimes 🧵/9

A way to see the depth of energy poverty in different countries today. Given the current electricity supply in different countries, how long could the average person run an air conditioner every day?

Just read that Abdullah Ibrahim has sadly died this week. One of my very favourite musicians. He died at 91 and played wonderful music until his very end. If you don't know him, listen to his Blue Bolero — it's the just the first 2 minutes of this. youtube.com/watch?v=L5i4stj4…

How will your country's demographics change this century? At Our World in Data we built a tool to let you see for yourself. The UN's assumptions are the starting point. But then you can adjust the three drivers of change — births, deaths, and migration — to what you expect.

The poorest economies in the world are not achieving economic growth. The consequence is that progress against the very worst poverty is coming to a halt. This is one of the worst problems in the world today, but hardly gets any attention.
