Rotation Method: Varimax with Kaiser Normalization a. Rotation converged in 9 iterations. The first principal component which explained the majority of the variation in the data set as shown in Table 2 was taken (that is, it served as the weight) and used in the computation of the vulnerability indices for the study area presented in Table 3. The result indicates that households in Oweto community are highly vulnerable with Composite Flood Vulnerability Index (CFVI) of -0.347. The level of vulnerability is as shown in the result is very high due to exposure and sensitivity levels. This is because Oweto is located right at the floodplain of River Benue and one of the major tributaries river Ajiba.
