This study provides a comprehensive global snapshot of wealth-based inequalities in higher education attendance. We draw on data from 117 countries to describe cross-national patterns in higher education attendance rates, disaggregated by wealth quintile and country income group. We then calculate four different indicators to quantify the size of wealth-based inequality in higher education attendance and completion for each country. Our findings point to large wealth-based inequalities in higher education attendance cross-nationally, which are: substantially larger than inequalities in secondary completion, larger in low- and middle-income countries than high-income countries, and negatively associated with national wealth. The results serve as a foundation for future studies on how country-level factors and policies exacerbate or reduce wealth-based inequalities.
