Data quality

• Length of intended stay

• Subjective; answer may change
• Intrusive
• Target group may have more reason than others to be suspicious of question intentions
• Surveillance of migrants
• Legal implications
• May be question-specific response problems
• May affect overall response quality

Notes:

Legal implications would include risk of outstaying visa restrictions

Would anybody answer this in a manner inconsistent with visa claims? Would that be an equivalent source of data? Clearly people may outstay visa, but this question would not change that…
