This report presents a trend analysis of food security indicators derived from the food consumption data collected in the 2000/1 and 2007 Household Budget Survey (HBS). The assessment of food insecurity at national and sub national levels can be used to evaluate the impact of food policies and programmes implemented during the reference period of study. The report provides a suite of food security indicators, including the Millenium Development Goal hunger indicator 1.9. It also assesses micronutrients and essential amino acids in the Tanzanian diet. This report presents the findings of the joint research work by the National Bureau of Statistics (NBS) and Food and Agricultural Organization of the United Nations (FAO). Financial support was given by the European Community (EC) through the EC-FAO Food Security Programme.
