The Educational Attainment Query gives a comprehensive picture of the distribution of education attainment and human capital among age groups and genders in over 180 countries. The query holds attainment data from three sources: 1) the Barro-Lee Dataset, 2) the UNESCO Institute for Statistics (UIS), and 3) the Wittgenstein Centre for Demography and Global Human Capital. Each dataset is summarized in the table below and explained in detail through the “About the Data” links.
