UNCTAD Statistics
Statistics is an inherent part of UNCTAD. Being the United Nations' focal point for the integrated treatment of trade and development and the interrelated issues in the areas of finance, technology, investment and sustainable development, UNCTAD compiles, validates and processes a wide range of data collected from national and international sources. Most of the time series cover
long periods, with some dating back to 1948, for
almost all economies of the world.
