I want to know the answer to the following question:
How much lower is the Swazi Real GDP growth in comparison to other Southern African Customs Union members is Swaziland?
All the background I'm provided with is that "Real GDP growth since 2001 has averaged 2.8%, nearly 2 percentage points lower than growth in other Southern African Customs Union (SACU) member countries.". Is that enough to answer the question?
