The International Monetary Fund (IMF) has released their World Economic Outlook (WOE) figures, downloadable here. The WEO database, released every April and October, contains selected microeconomic data for the IMF's analysis and projections of economic developments at the global, regional and country levels.
This database may be used to find data on national accounts, inflation, unemployment rates, balance of payments, fiscal indicators, trade for countries, aggegates and comodity prices whose data are submitted to the IMF.
Data are available from 1980 to the present, and projections are given for the next two years.
Data on Swaziland from 1996 - 2016 can be found on this link. Also, if you would like a soft-copy, simply email email@example.com and we would be more than happy to provide you with one.
