This dataset essentially supports the conclusion reached in the article titled: Household Water Inadequacy and Food Security Implications in Ghana: A National-Level Analysis of Probability and Contributing Factors. The objective is to investigate the probability of household water inadequacy in Ghana and its implications on food security. A nationwide survey dataset of 14,009 households was sampled through a multi-stage process, and were fitted to logistic, probit, and linear probability regression models. The variables identified in this dataset include net water consumed per household (y), household size (x1), region (x2), and location (x3).
