[Food Security Profile: Descriptive Statistics]

Policy formulation as well as implementation on issues like poverty and food insecurity presupposes information on a variety of variables that would explain the profiles across households/persons/regions. To begin with, one would like to know what is the dimension of food/nutrition security in terms of indicators like per capita income/consumer expenditure/food consumption/cereal consumption/calorie intake (based on recent information), and how far they vary across regions or socio-economic groups. To answer such questions, one option would be to collect sample information from different population groups and estimate descriptive statistics like averages. However, mean based statistics have limited use when the distributions are skewed, which we generally come across in empirical economic analysis. In such situations, to obtain an informed appreciation of issues, one would use order-based statistics. An illustration is provided with reference to the Indian XIth Five Year Plan which makes wrong inferences and policy recommendations by providing and interpreting only estimates of mean consumer expenditure and calorie intake.
