Germans now the Minority in Frankfurt: Over Half City’s Residents are Migrants
Figures show 51.2 per cent of people living there are either non-German, German citizens born abroad or Germans who are the children of immigrants.
The city's secretary of integration Sylvia Weber said: 'We have minorities with relatively large numbers in Frankfurt but no group with a clear majority.'
Turkish migrants are the largest non-German minority that are settled in Frankfurt, accounting for 13 per cent of the population.
A further 61 per cent of residents who were born abroad have come from other countries within the European Union.
The vast majority of immigrants had a legal and 'consolidated' status of residency.
The statistics were revealed in a 200-page document titled 'Frankfurt Integration and Diversity Monitoring'.
The report was designed to provide a grounding for the city to better respond to inequalities in areas like employment, education and housing.
'The trend is clear. We are a city without a majority,' added Ms Weber.
The report also shows disparities between immigrants and Germans - with 49 per cent of non-Germans falling below the poverty line, compared to just 23 per cent of original native citizens.
Immigrants are also less likely to be in work, with just 73 per cent of non-German men and 59 per cent of non-German women being in employment.
The data shows that 83 per cent of native German men are in work - as are 78 per cent of native German women.
It comes after a book published last year predicted that native Germans would soon be reduced to a minority in Frankfurt, Augsburg and Stuttgart.
The German cities would join others throughout Europe that have already seen immigrant numbers overtake natives, including Amsterdam, Brussels, Geneva and London.
The book, titled Super-Diversity: A New Perspective on Integration, criticised politicians' calls for migrants to integrate.
The authors criticised politicians' calls for migrants to integrate, arguing: 'In practice the result of these calls to assimilate is that an increasing number of citizens with a migrant background feels excluded and unwelcome.'
