Data on the private sector and trade are available from the World Bank Group's Private Participation in Infrastructure Project database, Enterprise Surveys, and Doing Business Indicators, as well as from the International Monetary Fund's Balance of Payments database and International Financial Statistics, the UN Commission on Trade and Development, the World Trade Organization, and various other sources. The complete list of indicators on the private sector and trade are found on our Private Sector topic page on data.worldbank.org.

Private Participation in Infrastructure Project database provides information on more than 4,800 infrastructure projects in 139 developing economies from 1984 to 2010. The database contains more than 30 fields per project record including country, financial closure year, infrastructure services provided, type of private participation, investment, technology, capacity, project location, contract duration, private sponsors, bidding process, and development bank support.

Enterprise Surveys gather firm-level data to benchmark the business environment of economies and assess how business environment constraints affect productivity and job creation. Standardized surveys conducted all over the world provide data on more than 130,000 firms in 128 countries. The survey covers 11 dimensions of the business environment, including regulation, corruption, crime, informality, finance, infrastructure, and trade.

Doing Business indicators measure business regulation, gauge regulatory outcomes, and measure the extent of legal protection of property, the flexibility of employment regulation, and the tax burden on businesses. Doing Business data are collected with a standardized survey that uses a simple business case to ensure comparability across economies and over time—with assumptions about the legal form of the business, its size, its location, and nature of its operation. Surveys in 183 countries are administered through more than 9,000 local experts, including lawyers, business consultants, accountants, freight forwarders, government officials, and other professionals who routinely administer or advise on legal and regulatory requirements.consult our Private Sector data page.
