<![CDATA[This study aims to analyze the spatio-temporal patterns and determinants of educational inequality across 42 districts/cities in Papua Island during the 2018–2021 period. Educational inequality is measured using the Education Gini Coefficient (EGC), which is calculated based on the years of schooling data of the population aged 15 years and over obtained from the raw data of the March 2018–2021 National Socio-Economic Survey (Susenas KOR) provided by the Central Bureau of Statistics (BPS). The analysis was conducted descriptively using choropleth maps and inferentially using the Geographically and Temporally Weighted Regression (GTWR) method with the best weighting function, Adaptive Gaussian. The results show that the average EGC increased from 0.4555 in 2018 to 0.5551 in 2020, before declining to 0.5198 in 2021. Higher educational inequality was found in inland, mountainous, and remote areas. The GTWR model demonstrated better performance compared to global regression (p-value = 0.0001). The factors that consistently influenced educational inequality were educational facilities, teacher–student ratios, internet access, and road accessibility. Therefore, educational equity policies should be adjusted to the local characteristics of each region.]]>
