An article from Eurostat database provides an introduction to the EU statistics on the integration of migrants.
Migrants’ integration is measured in terms of employment, health, education, social inclusion and active citizenship in the hosting country. A detailed analysis of integration indicators (except those on ‘health’) can be found in a series of specific articles.
Labour market indicators
During the period 2008-2016, migrants born outside the EU systematically recorded lower activity rates than EU-born migrants or the native-born population. In 2016, the EU-28 activity rate for migrants born outside the EU was 73.1 %. By contrast, the activity rate for the native-born population stood at 77.9 %.
In 2016, the EU-28 employment rate for the native-born working-age population was 71.8 %. Employment rate for working-age migrants born outside the EU was much lower, at 61.2 %.
EU-28 unemployment rate for migrants born outside the EU remained 8.4 %. higher than the rate for the native-born population in 2016.
An analysis for the EU-28 population aged 25-54 shows that in 2016 just over one third (35.5 %) of migrants born outside the EU had successfully completed at most a lower secondary level of education. This was a slightly higher share than that recorded for native-born individuals residing in their Member State of birth (18.6 %).
A 31.5 % share of core working-age migrants who were born outside the EU possessed a tertiary level of educational attainment in 2016 (just 2.1 percentage points below the average for the native-born population).
When compared with the native-born core working-age population, a slightly higher share of the migrant population participated in lifelong learning.
In 2015 in the EU-28, 70.5 % of nationals from 20 to 64 years of age lived in owner-occupied dwellings, compared with 32.1 % of all foreign citizens of the same age group.
The highest proportion of tenants in 2015 within the population of foreign citizens was observed in Slovenia, where 79.7 % of the foreign citizens were tenants, followed by Italy (78.9 %), Austria (77.6 %), Greece (77.5 %) and Ireland (76.7 %).
Slightly over 1 in 4 foreign citizens spent over 40 % of their disposable income on housing.
At risk of poverty and social exclusion
In 2015, 40.2 % of the non-EU-born population in the EU was assessed to be at risk of poverty or social exclusion (AROPE) compared with 21.7 % of the native-born population.
at EU level  the median income of nationals was higher (EUR 17 131) than the corresponding income of the foreign citizens (EUR 15 380) in 2015.
While the at-risk-of-poverty rate for children of nationals was 18.9 % in 2015, the corresponding rate for children with migratory background stood at 37.4 %.
At the end of 2015 around 7.7 million non-EU citizens were long-term residents in the EU, representing more than 40% of all non-EU citizens with valid residence permits.
In 2014 around 890 thousand foreign citizens received citizenship of the hosting country out of 34 million total foreign citizens residing in EU-28 Member States.
The highest naturalisation rate of all foreign citizens at EU level in 2014 was recorded in Sweden with 6.3 %, followed by Hungary with 6.2 % and Portugal with 5.3 %.
About nine out of ten of all foreign citizens who acquired citizenship of one of the EU-28 Member States in 2014 were previously non-EU citizens.
