Why Is Country Migration Data Generally Imperfect

Question

Examlex · Accepted Answer

The Answer is Migration data are generally imperfect or workforce analysis because they are typically derived from records kept by countries as they "control" their borders (i.e. monitor and record entries). Tourists often become workers, as do students who stay beyond their schooling. Others enter by avoiding border controls altogether, while some countries, notably members of the European Union (EU), have modified and even abolished such controls for member nations. At the same time, countries are much less likely to monitor and record exits. Thus, the extent of return migration, particularly circular migration, is widely ignored, even though migration experts consider it of prime importance.
