Merchandise trade has become an increasingly important contributor to a country’s gross domestic product (GDP), particularly for developing countries. Before the global financial crisis hit in 2008, merchandise trade as a percent of GDP for low- and middle-income economies was 57 percent, about 5% higher than for high-income economies. This is very evident in Europe and Central Asia (ECA) where merchandise trade accounts for 73 percent of the developing region’s GDP. Many ECA countries including Hungary, Belarus, and Bulgaria have merchandise trade to GDP ratios above 100 percent (155, 136, and 114 percent respectively in 2011), meaning merchandise exports are a large contributor to their overall economy.
Gross Domestic Product (GDP) estimates are some of the most heavily requested and used data published on data.worldbank.org. And as many users notice, the estimates are sometimes revised, occasionally resulting in large changes from previously published values. Why do revisions happen, what information do we publish about those revisions, and where do you find it?
