According to the International Monetary Fund’s 2019 forecast for Real Gross Domestic Product (GDP) growth, the annual percentage change among Commonwealth countries will be highest in Dominica this year and lowest in Nauru. Of the ten countries predicted to register the highest GDP growth worldwide, five are in the Commonwealth (Dominica, Ghana, Bangladesh, Kenya and Sierra Leone).  The average GDP growth forecast for the Commonwealth mirrors the global average at 3.7%. On a regional basis, Commonwealth countries in Asia are likely to grow at an average of 4.3%, followed by member states in the Caribbean and Americas and Africa regions, whose economies are expected to expand at an average of 3.8%. As defined by the IMF, real GDP growth is the most commonly used single measure of a country’s overall economic activity, representing the total value at constant prices of final goods and services produced during a specified time period.
