International Migration Statistics: Meeting the International Recommendations

Measuring International Skilled Migration: New Estimates Controlling for Age of Entry
The authors aim to improve 'brain drain,' or skilled emigration, data sets by taking into account whether migrants to OECD countries attained their education or training in the home or destination country by using age at emigration as the determining factor. There is a literature review that references other similar studies for those with further interest. The data and calculations are listed in a succint, easy to follow format.
Overcoming the Problems of Inconsistent International Migration data: A New Method Applied to Flows in Europe
This study examines how migration data might be harmonised across Europe, using a case study of 19 European countries between 2000 and 2007. It makes use of a strategy pioneered in 1993 by Poulain that takes into account both varying definitions between countries and measurement errors such as underreporting. The article covers data and methodology used as well as a critical look at the results.
