Methodology & honesty note
This list deliberately separates two very different kinds of number. Declared figures come from a legal disclosure mechanism the politician filed themselves — a US Ethics‑in‑Government‑Act filing, an Indian election affidavit, a Ukrainian e‑declaration, a Russian income statement. Estimated figures come from financial journalists and analysts (Forbes, Bloomberg, Sunday Times Rich List, etc.) reconstructing wealth that was never personally filed — common for monarchies and one‑party states with no public disclosure system.
For a few long‑serving leaders, the gap between these two numbers is enormous and politically contested — most famously Vladimir Putin, whose officially declared income is a few hundred thousand dollars a year, while some Western analysts and a 2017 US Senate testimony allege a hidden fortune as high as $200 billion. Neither figure is independently verifiable, so this page shows the declared one and states the disputed allegation in the profile rather than ranking him by it.
On "real‑time" data: there is no free, public, real‑time API for politicians' net worth — Forbes, Bloomberg and the Sunday Times Rich List are paid, proprietary products, and Google does not offer a key‑less live data feed either. What genuinely runs live on this page is the Wikipedia photo sync. Each profile also includes a one‑click "Verify on Google" link so you can pull the latest reporting yourself in real time.
