A composite socio-economic vulnerability map was generated by integrating various village level socio-economic indicators such as PD, TW, children below ages (0–6) and LR in the study area (Figure 2.7). The ranges of index value of the socio-economic vulnerability model are 3–10 classified in four classes, low (3–4), moderate (4–5), high (5–8), and very high (8–10), respectively.

Maximum SVI villages in the study area lie in a highly vulnerable zones that comprises 210.89 km² (55.35%) area, whereas 25.33 km² (8.62%) areas lie in the lowest vulnerable zone (Table 2.3). The village Saunda is in a very high vulnerable zone due to a higher density of socio-economic indicators such as PD, workers and children below ages (0–6).
