Immigrants are frequently younger than the German population

In 2016, 82 million people were living in Germany. Their average age was 44.3. 

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 persons with a migration Background in 2016 came from Turkey, Poland and Russia. While Russians and Poles were 38.1 are below the  average age of German population at 38.1 respectively, the Turks were on average much younger at only 33.2 years old. Compared to the European groups, it is noticeable that people with a migration background from Asia and Africa with an average age of 32.1 and 28.9 years are even younger. In 2016, around 75 percent of them were 45 and younger.

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.
