Data Sources & Methodology
GDP per capita levels: World Bank — NY.GDP.PCAP.CD (Current USD, most recent year available) · GDP per capita growth rates: World Bank — NY.GDP.PCAP.KD.ZG (Constant 2015 USD, annual %) · GDP growth data uploaded: NY.GDP.MKTP.KD.ZG (World Development Indicators, updated 2026-02-24)
5-year average is computed as the arithmetic mean of the most recent 5 years with available data. Catch-up formula: t = ln(GDP_B / GDP_A) / ln((1 + g_A) / (1 + g_B)), where g_A and g_B are annual per capita growth rates. All data fetched live from the World Bank API.
