Poverty remains one of the main development problems in the Special Region of Yogyakarta Province, which still records a relatively high poverty rate on Java Island. This study aims to describe the factors influencing the percentage of poor population, to examine the existence of spatial effects, and to determine the best model for analyzing poverty in the Special Region of Yogyakarta Province. This study used secondary panel data published by Statistics Indonesia (BPS), covering four regencies and one city during the 2021–2024 period employing the Spatial Panel method. The dependent variable is the percentage of poor population, while the independent variables consist of education indicators (mean years of schooling and expected years of schooling) and health indicators (life expectancy rate and life expectancy at birth). The results of Moran's I test (p-value = 0.007988) and the Lagrange Multiplier test proved a significant spatial dependence in the distribution of poverty. The best model is the Spatial Autoregressive (SAR) Fixed Effect model with an Adjusted R-Square of 0.9554794, in which mean years of schooling has a significant negative effect on poverty, while life expectancy rate and life expectancy at birth have significant positive effects. These findings imply that education-focused policy interventions are effective in reducing poverty in the Special Region of Yogyakarta Province.
