The IMF published on 6 August for the first time the World Revenue Longitudinal Dataset (WoRLD), which provides data on tax and non-tax revenues for 186 countries over the period 1990-2013. The database includes broad country coverage and time periods, and it is the result of combining in a consistent manner data from two other IMF publications -- the IMF Government Finance Statistics and World Economic Outlook (WEO)-- and drawing on the OECD’s Revenue Statistics and Revenue Statistics in Latin America and the Caribbean.
