Field survey, 2022 **p < 0.001. According to the relevant quartile value, the vulnerability index level was classified as high, medium, or low. Cramer’s V^# = Cramer’s V (tables bigger than 2 × 2 contingency table) measures the strength of an association between two categorical variables (Akoglu 2018). Cramer’s V < 0.10 interprets weak, > 0.10 < 0.15 interprets moderate, > 0.15 < 0.25 strong, and > 0.25 very strong association (Akoglu 2018)
