GDP by Sector API
Which parts of each economy are actually driving growth — real GDP growth broken down by economic sector, from the OECD's official Quarterly National Accounts as an API, live, no key. Headline GDP growth is one number, but it hides the story: whether the expansion is being carried by services, by industry, by construction or by agriculture, and which sector is dragging. Gross value added by economic activity decomposes real GDP into those sectors, so you can see, for any economy, that (say) services are growing while industry is in recession. It is the read economists and equity-sector investors use to understand the shape of the cycle, not just its size. The OECD harmonises and seasonally adjusts the real, chain-linked-volume figures so they are comparable across countries. This API computes the quarter-on-quarter and year-on-year growth of real gross value added in four sectors — services, industry (excluding construction), construction and agriculture. The country endpoint gives one economy's sector breakdown side by side and flags the leading and lagging sector. The services endpoint ranks every economy by services value-added growth (the largest sector in advanced economies); the industry endpoint ranks by industry value-added growth (the most cyclical). Each reading carries its own quarter and discontinued series are excluded, so the board is genuinely current. The sectoral-GDP / value-added cut — distinct from the headline GDP-growth board (the total), the monthly industrial-production index (a different measure, industry only), the annual IMF World Economic Outlook database, and the generic multi-provider data aggregator. Figures are quarterly, in percent.
