2017 Global Hunger Index Data

The Global Hunger Index (GHI) is a tool designed to comprehensively measure and track hunger globally, regionally, and by country. Each year, the International Food Policy Research Institute (IFPRI) calculates GHI scores in order to assess progress, or the lack thereof, in decreasing hunger. The GHI is designed to raise awareness and understanding of regional and country differences in the struggle against hunger. Since 2015, GHI scores have been calculated using a revised and improved formula. The revision replaces child underweight, previously the sole indicator of child undernutrition, with two indicators of child undernutrition—child wasting and child stunting—which are equally weighted in the GHI calculation. The revised formula also standardizes each of the component indicators to balance their contribution to the overall index and to changes in the GHI scores over time. The 2017 GHI has been calculated for 119 countries for which data on the four component indicators are available and where measuring hunger is considered most relevant. GHI scores are not calculated for some higher income countries where the prevalence of hunger is very low. The GHI is only as current as the data for its four component indicators. This year's GHI reflects the most recent available country-level data and from 2012 through 2016. It, therefore, reflects the hunger levels during this period rather than solely capturing conditions in 2017. The 1992, 2000, 2008, and 2017 GHI scores reflect the latest revised data for the four component indicators of the GHI. Where original source data were not available, the estimates of the GHI component indicators were based on the most recent data available. The four component indicators used to calculate the GHI scores draw upon data from the following sources: 1. Undernourishment: Updated data from the Food and Agriculture Organization of the United Nations (FAO) were used for the 1992, 2000, 2008, and 2017 GHI scores. Undernourishment data for the 2017 GHI are for 2014-2016. 2. Child wasting and stunting: The child undernutrition indicators of the GHI—child wasting and child stunting—include data from the joint database of United Nations Children's Fund (UNICEF), the World Health Organization (WHO), and the World Bank, and additional data from WHO's continuously updated Global Database on Child Growth and Malnutrition; the most recent Demographic and Health Survey (DHS) and Multiple Indicator Cluster Survey (MICS) reports; and statistical tables from UNICEF. For the 2017 GHI, data on child wasting and child stunting are for the latest year for which data are available in the period 2012-2016. 3. Child mortality: Updated data from the UN Inter-agency Group for Child Mortality Estimation were used for the 1992, 2000, 2008, and 2017 GHI scores. For the 2017 GHI, data on child mortality are from 2015.

全球饥饿指数（Global Hunger Index, GHI）是一套用于全面衡量并追踪全球、各区域及各国饥饿状况的工具。每年，国际粮食政策研究所（International Food Policy Research Institute, IFPRI）都会计算GHI得分，以评估各国在减少饥饿方面取得的进展或未达预期的情况。GHI旨在提升人们对全球各区域及各国在消除饥饿斗争中存在的差异的认知与理解。
自2015年起，GHI得分采用经过修订优化的计算公式得出。此次修订将此前作为儿童营养不足唯一衡量指标的儿童低体重，替换为两项儿童营养不足衡量指标——儿童消瘦与儿童生长迟缓，并在GHI计算中为二者赋予相同权重。修订后的计算公式还对各分项指标进行标准化处理，以平衡其对总指数的贡献，以及随时间推移对GHI得分变化的影响。
2017年GHI的计算覆盖了119个国家——这些国家拥有四项分项指标的相关数据，且饥饿状况衡量的现实意义较强。对于部分饥饿患病率极低的高收入国家，GHI并未计算其得分。GHI的时效性完全取决于其四项分项指标的最新数据情况。本年度GHI采用了截至2012年至2016年的最新国家级数据，因此其反映的是该时段内的饥饿水平，而非仅涵盖2017年的状况。1992年、2000年、2008年及2017年的GHI得分均采用了GHI四项分项指标的最新修订数据。若原始来源数据不可得，GHI分项指标的估算值将基于可获取的最新数据得出。
用于计算GHI得分的四项分项指标数据源自以下渠道：
1. 膳食摄入不足：1992年、2000年、2008年及2017年GHI得分的膳食摄入不足数据均采用了联合国粮食及农业组织（Food and Agriculture Organization of the United Nations, FAO）的更新数据。2017年GHI的膳食摄入不足数据时段为2014年至2016年。
2. 儿童消瘦与儿童生长迟缓：GHI的儿童营养不足衡量指标——儿童消瘦与儿童生长迟缓——的数据源自联合国儿童基金会（United Nations Children's Fund, UNICEF）、世界卫生组织（World Health Organization, WHO）及世界银行的联合数据库，以及世界卫生组织持续更新的《儿童成长与营养不良全球数据库》的额外数据；最新的《人口与健康调查》（Demographic and Health Survey, DHS）与《多指标类集调查》（Multiple Indicator Cluster Survey, MICS）报告；以及联合国儿童基金会的统计表格。针对2017年GHI，儿童消瘦与儿童生长迟缓的数据采用了2012年至2016年时段内可获取的最新年度数据。
3. 儿童死亡率：1992年、2000年、2008年及2017年GHI得分的儿童死亡率数据均采用了联合国儿童死亡率估算机构间工作组的更新数据。2017年GHI的儿童死亡率数据时段为2015年。
