Statistics in the National Ecological Footprint and Biocapacity Accounts are derived from many multinational databases with details about consumption, production, population, and economic variables by year and by country or on a world-total basis.

Key sources include International Energy Agency (IEA), United Nations FAOSTAT (including its databases of human population, crop and livestock products, food balances, forestry production and trade), FAO FishStat, Sea Around Us, UN COMTRADE, CORINE Land Cover, Global Agro-Ecological Zones (GAEZ), Global Land Cover (GLC), Global Carbon Budget, World Bank, and International Monetary Fund.

Multinational databases are sourced for national statistics to maximize the breadth and consistency of international statistics.
