The paper will present first results from the 2nd Leo level 1 study (deriving from data collection in 2018). Both, the first and second Leo-study, are concerned with the general question of reasons for adult illiteracy in Germany – a country with a highly developed educational system where nearly 100% of the population participates at least in obligatory schooling. With the 1st Leo-study, first insights in the question how many people in Germany can be assigned to the level of ‘functional illiterates’ were achieved. The estimates added up to 7,5 Mio – a number which is much higher than it was expected. With the 2nd study the authors follow the aim of identifying trends with respect to the levels of adult (il-)literacy in Germany. Background information (e.g. on age, gender, migration background, socio-economic factors) is available for in depth data analysis. The study includes around 7,200 German-speaking adults aged 18 to 64. The size and sample selection allow for conclusions about the total German population. In the presentation, the author will focus on the question: if and in what respects do migrant adults’ results in the Leo-study differ from those of the non-migrant population.
