Licence note
The FAQ says: "Data produced by us falls under our permissive CC BY license; you have permission to use, reproduce, and distribute it, provided that you cite us." WARNING: "Most of the data on Our World in Data comes from third-party providers (such as the WHO, UN, and World Bank) and is subject to the license terms of those providers." Recorded as Custom, not plain CC BY, because most indicators are third-party data under their own providers' terms.
Attribution
Required: cite Our World in Data (OWID-produced data is CC BY); third-party-sourced indicators must also credit the original provider and follow that provider's licence.
