# Global Wealth Distribution

Distribution of wealth globally, drawn from the Credit Suisse Global Wealth Databook (2010–2022) and the UBS Global Wealth Report 2024 (2023 data).

## Background

Every year since 2010, Credit Suisse (now UBS) has published a Global Wealth Report estimating how wealth is distributed across the world's adult population. The dataset covers the global wealth pyramid — how adults are distributed across four wealth bands — and country-level statistics for 20 major economies.

The headline finding: the top 1% of adults (those with more than USD 1M in wealth) hold roughly 45% of all global private wealth, while the bottom 55% (under USD 10k) hold less than 2%.
