2024 highlights 🪄
1️⃣ Making new available to the public 📊

The movement has gained traction, with public opinion and political will aligning to support it. We’re not there yet, but the momentum is undeniable! The proposal was put on the G20 agenda under the Brazilian Presidency in February, detailed in the Gabriel ZUCMAN's report in June, and endorsed by G20 finance ministers in November. Meanwhile, efforts continue to develop an inclusive and transparent on taxation. We look forward to continuing this work with partners EU Tax Observatory, ICRICT, Tax Justice Network.

🚨What’s new this year?
We’ve expanded the World Inequality Database to include foreign income, foreign wealth, public revenue, and public spending, providing deeper insights into the dynamics of inequality worldwide.

Key takeaways from this year’s update:
1️⃣ The world has grown richer, but this hides huge regional disparities.
2️⃣ Income inequality remains significant within most countries.
3️⃣ Global income growth rebounded post-COVID.
4️⃣ The 10 richest economies per capita are mostly tax havens with small populations.
5️⃣ Rich countries benefit from an “exorbitant privilege” in the global financial system.
6️⃣ BRICS are now the largest economies (PPP), though not in market exchange rates (MER).
7️⃣ The world’s 10 poorest countries are also major global debtors.
8️⃣ Poorer nations spend little on public services but much on debt repayments.
9️⃣ Rich countries have the highest levels of public spending.
🔟 Despite progress in data collection, inequality measurement remains scarce, and inequality reduction slow.

« [En Europe], on part avec moins d’inégalités primaires et on finit avec moins d’inégalités après redistribution. Nous disposons d’un modèle social plus protecteur [qu'aux Etats-Unis] », conclut Lucas Chancel, co-directeur du World Inequality Lab.

L’Etat-providence redistribuerait-il plus aux Etats-Unis qu’en Europe ? Moins taxés, les Américains les plus pauvres seraient mieux lotis par le système de redistribution que leurs homologues européens. Mais affirmer cela, c’est ignorer des inégalités plus structurelles.
