Explaining Wealth-Based Disparities in Higher Education Attendance: The Role of Societal Factors

This article examines factors associated with wealth-based inequalities in higher education attendance at the national level. We draw on data from 99 countries to calculate two distinct country-level indicators for the extent of wealth-based inequality in higher education attendance, namely the dissimilarity index (D-Index) and the Human Opportunity Index (HOI). We then examine each indicator’s association with country-level factors using a series of regression models. We find that secondary completion rates, national wealth, economic inequality and the extent of political egalitarianism are all associated with wealth-based disparities in higher education access. However, there are important differences between indicators. Economic inequality is associated with disparities in access but not the level of overall access. In contrast, politically egalitarianism is associated with expanded educational access, but not wealth-based disparities alone. The study suggests that both economic and political equality are associated with higher educational outcomes. Yet, it also cautions that how we conceptualize and measure educational equity can shape our interpretations of the extent of a country’s educational equity.
