DocumentEstimating Food Consumption Patterns by Reconciling Food Balance Sheets and Household Budget Surveys

No results found.Food Balance Sheets (FBS) are one of the most important sources of data on food availability for human consumption. This paper presents a method to improve the information on food consumption patterns of FBS by using national household budget surveys (HBS). In this paper, food commodities are categorized into 16 major food groups. For each food group, the contribution to the overall caloric intake is represented in shares. Item group shares of 64 surveys from 51 low and middle income countries are compared with shares from country-specific FBS. Given the countries represented in the data, the analysis evaluates food consumption of over 3 billion persons worldwide. A model based on a cross-entropy measure of information has been developed in order to reconcile aggregate food consumption patterns suggested by FBS and HBS. The latter model accounts for the fact that data from both data sources are prone to measurement errors. Overall, the results of the reconciliation suggest that aver age consumption of cereals, eggs, fish products, pulses and vegetables are likely to be underestimated in FBS, while fruits, meat, milk and sugar products are likely to be overestimated in FBS. Even though the suggested changes in average food consumption are moderate, the results imply considerable relative changes in the aggregate consumption of single food groups. Furthermore, the results imply that the aggregate consumption of fats is 2% higher than currently assumed. The updated consumption patterns provide valuable information from an agro-industrial perspective. Differences in updated consumption pattern with respect to the original FBS might suggest a re-evaluation of FBS elements of the value chain, starting from production and ending at food losses. -

Book (stand-alone)Deriving Food Security Information fromNational Household Budget Surveys
Experiences, Achievements, Challenges
2008Also available in:
No results found.The introductory paper in Part 1 summarizes the efforts and lessons learned from experiences in participating countries to improve food security statistics. Part 2 deals with food security estimates performed at national and sub-national levels in four countries. The papers of Cambodia and the Philippines are examples of food security statistics with gender analysis, while the Lao PDR and Mozambique papers are examples of sub-national analysis. Part 3 addresses measurement approaches of food acquisition and food consumption for the purpose of estimating food security statistics. The examples of Armenia, Cape Verde and Kenya depict detailed effects of how food data are collected on estimates of food security statistics in different settings. Part 4 reviews the policy implications of food security statistics on agriculture in Palestine and food security statistics trends in Moldova. Part 5 shows examples of enhanced analyses using panel data on food consumption in T ajikistan while linking child nutritional status with food security statistics in Georgia. Part 6 proposes methodological approaches for improving food security statistics for policy analysis; the first paper discusses household resilience to food insecurity using Palestinian data, while the last paper describes the linkage between critical food poverty and food deprivation. Finally, Part 7 provides a glossary of selected terminology related to food security statistics.
