This dataset provides a detailed analysis of global education trends, access, and inequalities over two centuries. It integrates four key data sources covering education attainment, out-of-school children, and gender disparities across countries and regions.

Spanning from 1820 to 2020, the dataset includes over 3,500 records and multiple variables such as country name, ISO code, year, population with or without formal education, and separate counts of out-of-school males and females.

By combining historical depth with recent insights, the dataset allows researchers, policymakers, and education experts to:

• Monitor long-term trends in basic and universal education.
• Identify gender gaps and populations at risk of educational exclusion.
• Compare regional and country-level disparities in educational access.
• Design targeted interventions to ensure equitable learning opportunities for all children and youth.

This resource serves as a vital tool for understanding both progress and ongoing challenges in global education, supporting data-driven decisions aimed at achieving inclusive and quality education for all.
