A counterargument to concerns about demographic change is that national identity is defined culturally and legally rather than ethnically. By this logic, a German is not solely someone born to two ethnically German parents but anyone who integrates into German society and holds citizenship. This is an issue without a clear-cut answer. At one extreme, there is genetic or ethnic determinism, which denies people the ability to successfully assimilate. The other extreme could lead to the claim that a German is simply anyone who gets the right documentation from the authorities, and any other criteria for evaluating German identity are illegitimate. Both approaches are absurd.
Careful interpretation
German authorities categorise individuals with a ”migration background” as those who immigrated after 1949, foreign nationals born in Germany, or German citizens with at least one parent who immigrated or was born as a foreign citizen. In 2005, this group comprised 18.7% of Germany’s population; by 2023, it had risen to 29.7%. This rapid demographic shift is particularly pronounced in urban centers, where in some cases, individuals with migration backgrounds constitute nearly half the population.
Despite this increase, the data requires careful interpretation. The migration background classification includes individuals of European descent, such as Poles, Romanians, and Italians, as well as ethnic Germans repatriated from Eastern Europe after World War II. Moreover, the classification only extends to one generation; third-generation descendants of Turkish immigrants from the 1960s and 1970s, if their parents obtained German citizenship, are considered German without a migration background. Consequently, official statistics may understate the long-term effects of immigration.
As of 2023, 9% of Germany’s registered population had ancestry from other EU countries, 5.8% from non-EU European countries, 10.5% from Asia (predominantly Turkey, Syria, Afghanistan, and Iraq), and 1.5% from Africa. The average age of Germans without a migration background is 47.2 years, compared to 35.3 years for those with one. Among those aged 50 and above, only 19.8% have a migration background, whereas among those under ten years old, the figure rises to 43%.
Is Demographics Political Destiny?
The political ramifications of these shifts are evident. Between 2019 and 2023, over 720,000 people were naturalised in Germany, equivalent to more than 1% of the electorate. The majority were of Syrian, Turkish, or Iraqi origin. Studies indicate that voters with migration backgrounds tend to support pro-immigration parties such as the Greens, Die Linke, or the SPD. This has led to speculation, as in other Western democracies, that left-leaning parties may favor liberal immigration policies to expand their voter base. In 2024, the German government introduced reforms to ease the naturalisation process further, signaling a continued commitment to migration-friendly policies. However, as the recent success of Donald Trump among Latino voters in the United States shows, this strategy can easily backfire. Citizens of immigration background often strongly experience the negative impacts of unregulated mass immigration themselves and identity politics may easily get traded in for bread and butter issues.
Germany’s demographic trajectory is distinctive. It has sustained one of the world’s lowest fertility rates—persistently below 1.5 children per woman—while simultaneously adopting some of the most liberal immigration policies. This dual dynamic is driven by both economic imperatives, such as labor shortages, and humanitarian commitments. However, integration outcomes vary significantly. Migrants from EU countries or other developed economies often integrate more seamlessly than those from societies with different social structures, such as those characterised by clan-based family networks and arranged marriages.
Demographic change invariably reshapes a nation’s character. Whether this transformation strengthens or challenges Germany is a matter for its electorate to decide. What is clear, however, is that migration will remain a defining issue in the country’s political landscape, particularly in the upcoming federal elections.
