World Development Indicators (core indicators)世界发展指标 (WDI，核心指标)

The World Development Indicators are the World Bank's primary compilation of cross-country development statistics, drawn from officially recognised international sources and harmonised so that economies can be compared with each other and over time. Coverage runs from 1960 to the present.

Twelve headline indicators are hosted here: GDP and GDP per capita in current US dollars, real GDP growth, consumer price inflation, total population, trade as a share of GDP, net FDI inflows as a share of GDP, unemployment, life expectancy at birth, the urban population share, government consumption as a share of GDP, and internet use.

The full WDI release contains roughly 1,500 indicators and is far too large to publish as a single web dataset, so this is a deliberate subset. The complete source CSVs are delivered alongside, and any other indicator can be extracted from them the same way. Regional and income-group aggregates such as 'World' or 'High income' are excluded so that the map and rankings contain only individual economies.

世界发展指标是世界银行最主要的跨国发展统计汇编，取自国际公认的官方统计来源，并做了口径统一，使各经济体之间以及不同年份之间可比，数据自 1960 年至今。

此处托管 12 个核心指标：现价美元 GDP 与人均 GDP、实际 GDP 增长率、居民消费价格通胀率、总人口、贸易占 GDP 比重、FDI 净流入占 GDP 比重、失业率、出生时预期寿命、城镇人口比重、政府消费占 GDP 比重，以及互联网使用率。

WDI 完整发布约含 1,500 个指标，体量远超单个网站数据集所能承载，因此这里是有意选取的子集。完整原始 CSV 已随交付附上，其他指标可按同样方式从中抽取。「World」「High income」这类区域与收入组聚合行已剔除，以保证地图与排名只含单个经济体。
