Questions • Under the current demographic conditions: • Is the Third Demographic Transition materialising in the European countries? • Has migration the same effect / timing across ages?

What makes it possible • EU Regulation on migration statistics (2007) and on demographic statistics (2013) • Country of birth (native-born, EU, non-EU) • Citizenship (national, EU, non-EU, stateless)
• Data now available for the few latest years • Input to this exercise: average of the period 2014-2016

Geographic standpoint matters • The classification of an individual by his/her MBG depends upon the reporting country. • Examples: • A native-born person with national citizenship in a given Member State is, in another Member State, a foreign-born with EU citizenship other than national • A person born outside EU and holding a non-EU citizenship migrating from a EU MS to an EFTA country could be any combination of national/non-EU country of birth and citizenship in the receiving (nonEU) country 11

Caveats • Input data: • Input immigration and emigration flows adjusted for consistency • Any special event occurred in 2014-2016 not excluded • Redistribution of unknowns • Some input data require investigation
• Technicalities: • Imputation of missing rates (not for acquisitions) • Further work on modelling of age patterns (ongoing)
• Assumptions: • No holders of multiple citizenship • New-borns take the citizenship of the mother (with one exception) • 2nd generation migrants have (double) higher probabilities of acquiring the citizenship of the hosting country than immigrants 19

‘Brexit’ variant • Assumptions (applied from 2019): • UK attributed the migration flows from non-EU countries and a proportion of former EU flows (here arbitrarily set at one third) • Within the EU, Brexit affects the destination but not the size of the emigration flows from EU MSs directed to other EU MSs.

Answers • Under the current demographic conditions: • The effect of migration on population composition depends upon the integration type. • In multicultural societies, German-speaking countries would experience the TDT before the end of the century. Several other countries may follow would the conditions persist. • At the very beginning – well before the (semi) stableequivalent population is reached – the effect of migration on population composition would be larger (quicker TDT) in younger ages. However, this pattern does not necessarily apply to each single country. 35

Novelties of this exercise • • • • •
High level of data disaggregation (‘granularity’) Multi-country approach (consistency of intra-EU flows) New statistical perspective (‘migration background’) Different hypotheses on migrants integration Brexit
• Virtual extensions: • Sub-national breakdown (down to NUTS3) • Finer disaggregation of intra-EU migration flows • …and - naturally - changing rates… 36
