The most extensive and reliable source for socio-economic and development data is probably World Bank’s annually published World Development Indicators (WDI) database. The recent WDI, published in 2008, has approximately 800 indicators for 209 economies. Economies in WDI have been organized in 18 groups based on income, geography, and indebtedness criteria. Data in the WDI database are categorized in six major areas: overview, people, environment, economy, states and markets, and global links.

Revision as of 23:22, 14 April 2016

There are 315 series pulled from the World Development Indicators (WDI) in 2015. 67 of these are used in the preprocesr.

The most extensive and reliable source for socio-economic and development data is probably World Bank’s annually published World Development Indicators (WDI) database. The recent WDI, published in 2008, has approximately 800 indicators for 209 economies. Economies in WDI have been organized in 18 groups based on income, geography, and indebtedness criteria. Data in the WDI database are categorized in six major areas: overview, people, environment, economy, states and markets, and global links.

The major advantage of the WDI database is that it has longer time series coverage, for example, most of the indicators cover data since 1960. The World Bank collects data for particular series from the organizations who are pioneers in those areas. For example, WDI compiles external account data, like export, import, current account, debt etc. from the International Monetary Fund (IMF), and population data from United Nations Population Division. Major data sources for WDI are World Bank national accounts data, OECD National Accounts, Food and Agriculture Organization, United Nations Educational, Scientific, and Cultural Organization, World Health Organization, International Labor Organization, International Telecommunication Union etc. WDI database are available in three formats- online (https://publications.worldbank.org/subscriptions/WDI/), published report in hard copy and CDROM version.

Some financial data series from the WDI database, used in IFs analysis, have been converted into billion US$ from current prices at US$ and some series related to population have been transformed into million figures. The IFs system also needed to calibrate some data series as percent of GDP in constructing social accounting matrices.
