Most Central American migrants cite economic conditions as a reason for their decision to leave their countries. For some it is the only reason: they migrate because they can no longer survive where they are. For some, their loss of livelihoods is due to environmental pressures such as drought, hurricanes or the long-term effects of climate change. For others, their decisions to migrate are the result of both economic desperation and personal insecurity due to criminal violence. For almost all of them, poverty and loss of hope that conditions will improve are factors in their decisions to move.
