I want to know the answer to the following question:
How much money did overseas Nigerians send home in 2007?
All the background I'm provided with is that "According to the International Organization for Migration, Nigeria witnessed a dramatic increase in remittances sent home from overseas Nigerians, going from USD 2.3 billion in 2004 to 17.9 billion in 2007.". Is that enough to answer the question?
Answer: yes
