Statistics

Outflows

Data on emigration are sparser and even less reliable than those on immigration.

Many countries do not collect this information in any form. A part of the problem is that people do not have much incentive to notify the authorities of their departure. And the emigrants more likely to do are nationals rather than foreign citizens. As a result, published statistics tend to underestimate emigration. Subtracting the data in table 2 from those in table 1 should give in principle give net migration. But given the uncertainties in the data this may not be wise. In any case, there other ways of getting this information, as explained on the next page.
