Despite what films suggest, Interpol has no officers empowered to investigate or arrest anyone on the ground. Founded in 1923 and headquartered in Lyon, it connects the police forces of 196 countries: it runs databases, such as one of stolen passports, and circulates notices.

That's the estimate from a WHO-led study published in The Lancet in 2024, covering the half-century since the Expanded Programme on Immunization was launched in 1974.

According to the World Gold Council, about 216,000 tonnes of gold have been mined in all of human history. Because gold is so dense (19.3 tonnes per cubic metre), it would fit in a cube about 22 metres on each side, roughly the height of a seven-storey building. Strikingly, about two-thirds of it has been mined since 1950.
