**Analysis**
The text appears to be a statistical report on international trade, specifically focusing on the composition of world exports and imports by major commodity groups in 1960 and 1980. The data is presented in tables, which suggests a strong emphasis on quantitative analysis and economic indicators. The content does not seem to be related to human health, education, employment, or humanitarian aid, and it does not mention specific cultural or scientific topics. The focus on trade and commodities suggests a connection to economic development and international trade.
