Immigrants are frequently younger than the German population

In 2015, 81 million people were living in Germany. Their average age was 44.7. 

Given the low birth rates, the younger people in Germany cannot, in purely mathematical terms, replace their parents' generation. But immigrants can close this gap, as they are frequently younger than the average age of the German population, and of that of the Gastarbeiter, or "guest workers,” who immigrated decades ago. 

Most foreigners in 2015 came from Turkey, Poland or Italy. While Turks and Italians were slightly below the average age of the German population, at 43.2 and 43.3 respectively, the Poles had an average age of just 37. Just under half of the 740,000 Polish immigrants were 25 and 45 years old. 

Strikingly, compared with the European groups, immigrants from Asia and Africa are even younger, with an average age of 31.4 and 32.1. In 2015, around 80 percent of them were aged 45 and under. 

These young immigrants could remain on the German labour market for a long time to come, palliating the shortage of qualified workers and contributing to prosperity and economic success. This is if they have the suitable qualifications.
