    • 2.1: Introduction
      This page discusses survey methods for assessing food availability at national and household levels, emphasizing Food Balance Sheets (FBS) and Household Consumption Surveys (HCS). It highlights that FBS offers national data without details on distribution, while household surveys lack demographic information. Indicators from these surveys are useful for monitoring food insecurity based on the quantity and quality of food available.
    • 2.2: Food Balance Sheets
      This page outlines the significance of Food Balance Sheets (FBS) in low-income countries for tracking food availability despite underestimations from informal sources. The FAO has improved FBS methodology to enhance data accuracy for dietary analyses related to hunger and food security. It discusses the global prevalence of undernourishment, particularly in Africa, and metrics for evaluation, including dietary energy supply and micronutrient availability.
    • 2.3: Household Surveys
      This page discusses household surveys assessing food availability, focusing on Household Food Consumption Surveys (HFCS) and Household Consumption Expenditure Surveys (HCES). HFCS provides detailed consumption data but is less common, while HCES, more cost-effective, faces challenges in accurately capturing food consumed outside the home. Recommendations for improvement include standardized classification systems and specific data collection methods.
    • 2.4: Comparison of Food Balance Sheets (FBS) and House­hold Consumption and Expenditure Surveys (HCES)
      This page discusses the measurement errors in Food Balance Sheets (FBS) and Household Consumption and Expenditure Surveys (HCES). FBS provides a cost-effective national overview but suffers from data quality issues, while HCES offers detailed household-level insights at a higher cost with no standardization.
    • 2.5: National and house­hold surveys in the global assess­ment of food security and diet quality by age and sex
      This page highlights the significance of individual-level quantitative food consumption data for evaluating nutrient intake in populations. Despite the scarcity of such data in low and middle-income countries, global databases like the GDD and IHME offer modeled dietary data to bridge this gap. They facilitate the analysis of dietary patterns and health concerns, aiding in the identification of dietary risks and supporting the achievement of global health objectives.
