GDP Revisions and Updating Statistical Systems in Sub-Saharan Africa: Reports from the Statistical Offices in Nigeria, Liberia and Zimbabwe

摘要

The quality of economic statistics in Africa has been likened to a statistical tragedy. Currently many statistical systems in Africa are being updated. This report from the statistical offices in Nigeria, Liberia and Zimbabwe documents that base year, data and methods used to generate GDP estimates currently date from 1990, 1992 and 1994. There is a growing need for macroeconomic statistics, but a rebasing of GDP estimates is costly and time consuming. The work to update economic statistics in Nigeria and Zimbabwe is still ongoing, while efforts to generate an authoritative estimate of the Liberian economy have proved unsuccessful.
