Even those who had completed a higher level of education were found to be affected, comprising 12 percent of those found to be illiterate.
The study is said to be Germany’s first comprehensive examination of illiteracy.
A study has revealed that the number of illiterate adults in Germany is twice as high as previously thought, and over 7 million people are unable to read and write well.
According to the study, which surveyed some 8,000 German citizens and was published by the University of Hamburg, the number of Germans aged between 18 and 64 who are illiterate is now almost 7.5 million - or 14 percent of the work force.
The study also revealed that 300,000 German citizens can’t read or write at all, while another 2 million are unable to read or write more than a series of random words. A further 5.2 million are able to make out short sentences, but would fail to understand a longer text.
In addition, sixty percent of those found to be functionally illiterate were men, and 40 percent were women.
