The EDU20C Project is modelling the stages of educational development by reconstructing the educational composition by 5-year-age-groups and sex for 30 countries in the 20^th Century by using an adapted multidimensional cohort component model. The aim is to create a comprehensive, consistent and comparable timeseries (5-year-projection steps) that can sketch potential patterns, pathways and paces in the education transition from low to highly educated societies from 1900 until now.

This dataset is used to study potential correlations and impact of the education transition in multiple countries on societal, demographic, economic and technological changes. This might have predictive power for the projection of future socioeconomic developments. This has a high relevance for research and policy making, e.g. education programmes.

This reconstruction is based on population data by 5-year-age-groups, sex and highest educational attainment. In total, we collected and harmonized more than 1.200 recent and historical data points for 185 countries and about 235 data points for 30 countries, which would be presented at EPC, on educational attainment and literacy. The presentation at the EPC 2018 will cover our methodological approaches (data collection, harmonization, reconstruction), the country comparison on educational development for 30 countries in the 20^th Century and the correlation with other transition models.
