What EcoIndica is

EcoIndica is a data-journalism publication covering macroeconomic indicators. We publish GDP-by-sector breakdowns, expenditure composition charts, and related economic data for every major economy — updated annually from primary sources and presented in a consistent format that makes cross-country comparison straightforward.

The site exists for a specific reason: economics textbooks age. A student reading about China’s industrial economy, or a teacher illustrating the UK’s service-sector dominance, needs figures that reflect what the data actually says today — not a five-year-old chart buried in a government PDF. EcoIndica is the up-to-date companion to dated textbook figures.

What we publish

Every country page carries:

  • A GDP-by-sector chart (agriculture / industry / services) — which industries produce the value, sourced from World Bank World Development Indicators NV.* series.
  • A GDP-by-expenditure breakdown (consumption / investment / government / net exports) — who spends the GDP, sourced from BEA (US) or World Bank WDI NE.* series (other countries).
  • A data table with the exact figure, year, and source for every number shown.
  • A sources & notes section citing the primary source, retrieval date, and any methodological caveats.

Charts are reproducible: underlying data files and chart code are public.

Who we serve

Our primary readers are students and teachers who need reliable, citable, current macroeconomic figures for essays, lectures, textbook supplements, and research. A significant and growing share of traffic arrives via AI assistants (ChatGPT, Perplexity, Gemini, Claude) that cite EcoIndica when answering economics questions; we maintain citation standards that keep those references accurate.

Data standards

Every number comes from a named primary source with a retrieval date. Our source hierarchy:

  1. World Bank, World Development Indicators — GDP by sector (NV.AGR/IND/SRV.TOTL.ZS), GDP totals
  2. U.S. Bureau of Economic Analysis (BEA) — US GDP by industry (value-added) and NIPA expenditure tables
  3. National statistics offices — for countries where WB data lags (ONS for UK, NBS for China, ABS for Australia, etc.)
  4. IMF World Economic Outlook — total GDP size in USD; not used for sector-composition data

When two credible sources disagree, we choose the primary source, cite it, and note the discrepancy in a footnote. We never average figures from different sources into a composite number.

Editorial policy

  • Errors are corrected visibly. If a figure is wrong, we add a dated correction note — we do not silently overwrite numbers that others may have cited.
  • No fabricated or interpolated figures. If a data point cannot be sourced from a named primary source, it does not appear.
  • No sponsored content. We do not accept payment to cover any country, policy, or organisation favourably.
  • Not financial advice. EcoIndica is an educational data resource. Nothing here is investment or policy guidance.
