Title: Spatial autocorrelation and regional disparities in household welfare in Indonesia
Authors: Takafumi Kubota - Tama University (Japan) [presenting]
Abstract: Household welfare in Indonesia exhibits persistent regional disparities, yet its spatial structure has not been sufficiently examined using large-scale household Survey microdata. An analysis combining Indonesian National Social Economic Survey (Survei Sosial Ekonomi Nasional SUSENAS) microdata with regional boundary data and spatially aggregated indicators examines spatial patterns of welfare. The investigation focuses on whether household welfare and related deprivation measures display spatial autocorrelation across provinces or districts, and whether spatial dependence remains after controlling for household and regional characteristics. The empirical strategy begins with descriptive spatial diagnostics, including Moran's I and local indicators of spatial association. Depending on data availability and geographic identifiers, the analysis may be extended to spatial lag or spatial error models at the administrative level, while preserving comparability and confidentiality. The analysis also examines how welfare indicators, urban-rural composition, and regional context shape disparities. If detailed geographic identifiers are unavailable, the analysis is conducted at a more aggregated regional level, focusing on robust comparison of spatial patterns rather than point-level inference. The contribution clarifies the feasibility of spatial welfare analysis using Indonesian household microdata and provides evidence on the regional clustering of welfare inequality.
