Young or very young, still have not built their family, a high educational level and in 60% of cases are Italian. They are the immigrants of Bologna, as in the research of the municipality. The analysis also reveals that the town's population grows thanks to new arrivals.
Every year more than 15,000 people, on average, take up residence in the city of Bologna, while 10,500 decide to leave. Over the five-year period 2011-2015 the balance is positive for over 22,500 units. A plus sign confirming, writes a note of the municipality, "as the migratory movement is indispensable to prevent the decline in numbers of residents." But who are these immigrants? They are mainly Italian citizens. Moreover, going to observe the data more deeply, they are mostly young (62% under 35 years), "which constrain the inevitable increase in the age" and contribute to enrich the "human capital."
During last twenty years Bologna immigration flows are more intense than those of emigration: continuously since 1996, to be precise. And this allows the increase of the city population, counted 387,000 people at the end of 2015, going to cover the negative balance between births and deaths (-7,912 in five years).
Italians immigrants were said to prevail numerically on foreigners. The flow of immigrants from Italy comes primarily from neighbouring areas (35.9% comes from Emilia-Romagna region, and 27% of these from the Bologna subway), but the higher the percentage of those arriving from South Italy and the Italian islands (22.8%). However, foreigners are Europeans (almost 42%), Asians (33.6%) and Africans (18.4%). The largest absolute citizenship in 2011-2015 five-year period is represented by Romanians (arrivals are around 4,741).
The education of those arriving: 28.7% have a university degree, 33.4% have a high school diploma, 22% middle school. So, who comes is on average more educated than the population of Bologna, and allows to bring to 22% the proportion of graduate urban population, against an average of 10% nationwide.
Who leaves Bologna (53,000 persons in the period 2011-2015) is in four out of five cases an Italian.
In 61% of cases remaining in Emilia-Romagna, and often moving in one of Bologna hinterland municipalities. As for the choice to go abroad, Bologna in the 2011-2015 five-year period it has lost just under 500 residents a year to emigration to other countries.
