The numbers behind almost every China-vs-peers comparison
Almost any China-vs-peers comparison — on GDP, poverty, schooling, health, or the environment — draws on this database. The World Development Indicators are the World Bank’s master statistical compilation: roughly 1,400 to 1,600 time-series indicators (the Bank’s own pages disagree on the exact count, so this page states the range) covering 217 economies from 1960 to the present.
What it contains
Six broad themes: poverty and inequality; people (education, health, demographics, gender); environment; the economy (national accounts, trade, finance); plus business, military, and communications; and debt, aid, and migration. The series began life as annex tables to the 1978 World Development Report; the annual print volume ran until 2017, and since 2018 the WDI website itself has been the discovery platform. Everything is open and free, including a public API (api.worldbank.org/v2) that serves all indicators programmatically at no cost and without a key.
How it is made — and what that means for China
The WDI does not independently measure anything. It compiles and harmonizes statistics produced by national statistical offices, UN agencies, the Bank, research institutions, and private contributors, with sources-and-methods notes documented per indicator. For China, that means WDI values are the official National Bureau of Statistics series. Known issues — census-driven GDP revisions, definitional choices, the absence of independent verification — travel with the data unchanged. Treat China’s WDI series as the official record, not as independently validated measurement.
The WDI also does not measure governance quality, political freedom, or institutional characteristics. Those belong to other products — the Worldwide Governance Indicators, the Freedom in the World dataset, Polity — and this page should never be cited for them.
Using it well
Pair WDI series with the Penn World Table for PPP-adjusted income comparisons and with governance measures for political-economy analysis. The Bank’s Atlas of Sustainable Development Goals is built on WDI data, and countless third-party dashboards draw on it through the free API. Because historical values change whenever sources update, any cross-year comparison should be checked against the revision history and errata files bundled with the Data Catalog entry (0037712).
Where it breaks
- The indicator count varies across official Bank pages (1,400–1,600), reflecting a database that grows and changes.
- Coverage is uneven: many indicators have sparse early-year or small-country data.
- China series carry the full reliability caveats of official Chinese statistics (see above).
- Do not confuse the WDI with the Bank’s DataBank (the query platform), the Worldwide Governance Indicators (a separate product), or the World Development Report (the annual flagship publication the WDI began as an annex to).
