Food is a basic necessity but food insecurity is still prevalent around the world especially in third world countries despite continuous efforts to cope with it. Food security is a multidimensional phenomenon which encompasses availability of food, access, its utilization and sustainability. This study sought to examine the overall situation and socio-economic determinants of household food insecurity in Pakistan. Multiple methodologies are employed to examine the potential determinants of household food insecurity, the incidence and depth of food insecurity in Pakistan. An index is formed to know the incidence and overall situation of food insecurity in Pakistan. Household Dietary Diversity Score and Food Insecurity Gap are used to find out the access of food and depth of food insecurity respectively. Descriptive Analysis and Logistic Regression analysis are used to determine the potential determinants of food insecurity in Pakistan. Findings of the research are that Pakistan is facing a severe food insecurity condition where 70 percent of the households are food insecure which is very alarming. Household size, gender of household head, annual income of the household, age of household’s head, annual savings, cash transfers (BISP in case of Pakistan), expenditures, agricultural land holdings and education of household head are found to have a significant impact on state of affairs of food insecurity in Pakistan. Findings of the study suggest that measures should be taken to: increase the income of people, increase the employment opportunities, increase the literacy level of people, decrease household size and dependency ratio and women should be empowered economically to deal with the problem of food insecurity.
