Social vulnerability at the village scale is often presented in aggregate form, obscuring variation among community units (RW). This study aims to analyze the level and spatial pattern of social vulnerability to lahar floods in Linggajati Village, Tasikmalaya Regency, at the RW scale. A quantitative approach was applied using secondary data from the 2023 Linggajati Village monograph. The Social Vulnerability Index (SVI) was calculated through scoring, score normalization, and weighting of five parameters: population density (60%), gender ratio, vulnerable age groups, disability, and poverty (10% each). The results show an average village SVI of 0.82, classified as high. Five RWs are in the high category: RW 1 and RW 5 (0.93), RW 3 (0.90), RW 4 (0.83), and RW 6 (0.70), while RW 2 is in the moderate category (0.63). Population density and poverty are the dominant factors. These findings support prioritizing high-vulnerability RWs through inclusive evacuation-route planning and strengthened capacity for vulnerable groups.
