Summary of the project

The European Union faces an urgent need for comprehensive and comparable statistics on international migration in order to support the development of a common EU migration policy. Yet required migration data are missing. They are, and will continue to be, produced at national level from a wide range of sources and according to various rules. When the data are not there, models can be used to fill in the gaps. The trust in statistical estimation methods is expressed also by the European Commission. The recently adopted Community legislation on migration statistics provides for use of estimation methods for adjusting data to meet the harmonized definition.

The aim of my PhD research is to develop a method to overcome one of the main sources of data incomparability, namely inconsistencies in definitions and measurements of international migration in terms of time dependence. The model will be built on the identified data typology that results from different ways that migration is conceptualized and measured. The impact of different data types on reported volume of migration will be illustrated based on statistics on flows between the EU countries.
