This chapter finds that food security in Vietnam showed improvements that were concentrated among the richer households, although there was some improvement among the poorer strata as well. It focuses on the calorie/expenditure elasticity and compares results for the years 1993 and 1998. It shows that this link is strong and that calorie income elasticity changed in the expected direction. In general, food security improved in Vietnam during 1990s although considerable differences still remain among expenditure deciles and among regions due to the accentuated spatial difference.
