Answer: Chance for better wages
Step-by-step explanation:
Forced migration as the term implies refers to the movement of people involuntarily from their resident region or home to seek refuge in another area as a result of potential or already incurred dangers such as natural disasters, lack of food or the chance of imprisonment or death.
For instance, the migration of Rohingya Muslims facing persecution in Burma, the displacement of people in Northern Nigeria as a result of the Boko Haram insurgency and the recent "2020 Caravan" that comprised of thousands of people from countries like El Salvador and Honduras who tried to enter the United States earlier this year.
Having to move for a chance of better wages is not a reason for forced migration because such an action is not involuntary.
