The World Bank’s World Development Report, published annually since 1978, is an invaluable guide to the economic, social, and environmental state of the world today. Each report provides in-depth analysis and policy recommendations on a specific and important aspect of development—from agriculture, the role of the state, transition economies, and labor to infrastructure, health, the environment, and poverty. Through the quality and timeliness of the information it provides, the report has become a highly influential publication that is used by many multilateral and bilateral international organizations, national governments, scholars, civil society networks and groups, and other global thought leaders to support their decision-making processes. This corporate flagship undergoes extensive internal and external review and is one of the key outputs of the World Bank's Development Economics unit.
