Enterprise Surveys Microdata Calalogue
The Enterprise Surveys cover a broad range of business environment topics including access to finance, gender, corruption, infrastructure, innovation, competition, informality, and performance measures. Firm-level surveys have been conducted since 2002 by different units within the World Bank. Since 2005-06, most data collection efforts have been centralized within the Enterprise Analysis Unit. The individual country datasets, aggregated datasets (across countries and years), panel datasets, and all relevant survey documentation are available to those who register (registration is free).
