ITALY

Figures on this page present estimates of Italy’s irregular migration population between 2008 and 2023 and corresponding assessments of their quality, which were compiled and carried out under the MIrreM project. Other MIrreM outputs, such as working papers and briefs, related to Italy are displayed on this page.

Estimates can be viewed as a number, as a share of the total population and as a share of the foreign-born population not covered by free movement policies (i.e., in Europe, those who were born in countries outside of EU Free Movement and in the UK and Ireland, those who were born outside of the Common Travel Area). 

The Estimate Quality brings together appraisals of an estimate’s accessibility, documentation, methodology, reliability and underlying data into an aggregate score and band. 

• Estimates that scored between 4 and 8 points were graded as low quality
• Estimates that received scores greater than 8 points and as high as 10 points were appraised as medium quality
• Estimates that exceeded valuations of 10 points (up to the maximum score of 12 points) were classified as high quality. 

For more information on how these data were compiled and assessed, please refer to the MIrreM Working Paper, The Irregular Migrant Population of Europe (Kierans and Vargas-Silva, 2024).
