When you have a central research question you can then break it down into 3-5 sub-questions. For example:
SQ 1. What were the migrant households’ economic status before migration?
SQ 2. How much do migrant households receive each month?
SQ 3. How much do remittances contribute to household income?
SQ 4. What does the extra income from remittances allow migrant households to buy or invest in? (How is the extra income used?)
