A flagship development statistic from Our World in Data: the latest value for a country plus
a short multi-year trend, with full source attribution. ONE source, MANY indicators (breadth) —
CO2 per capita, population, fertility, urbanisation, GDP-per-capita (a development stat in PPP,
NOT a market price), extreme poverty, R&D spend, Human Development Index, literacy, internet
access, electricity access. Distinct from `global_macro` (World Bank): OWID adds the long-run
development + climate set. `indicator` = a slug/alias from the curated allowlist (default
"co2-emissions-per-capita"; aliases: co2, pop, gdp, hdi, literacy, internet, poverty, fertility,
urban, rd) — call indicator="list" for the full menu. `country` = ISO-3 code (AUS, USA, CHN,
GBR, IND, …); omit for the World aggregate. Source: Our World in Data (ourworldindata.org) —
OWID's processing layer is CC BY 4.0, keyless; every response carries BOTH OWID's attribution
AND each underlying producer's citation + licence. Only indicators whose underlying sources are
cleared for commercial re-serving (CC BY / CC BY IGO / CC0 / public domain) are served — a
fail-closed runtime gate refuses any non-redistributable indicator. Annual-ish statistics, not a
live-telemetry feed.
