Global Burden of Disease Study 2021 (GBD 2021) Socio-Demographic Index (SDI) 1950–2021

The Global Burden of Disease Study 2021 (GBD 2021), coordinated by the Institute for Health Metrics and Evaluation (IHME), estimated the burden of diseases, injuries, and risk factors for 204 countries and territories and selected subnational locations. Developed by GBD researchers and used to help produce these estimates, the Socio-demographic Index (SDI) is a composite indicator of development status strongly correlated with health outcomes. It is the geometric mean of 0 to 1 indices of total fertility rate under the age of 25 (TFU25), mean education for those ages 15 and older (EDU15+), and lag distributed income (LDI) per capita. As a composite, a location with an SDI of 0 would have a theoretical minimum level of development relevant to health, while a location with an SDI of 1 would have a theoretical maximum level. This dataset provides tables with SDI values for all estimated GBD 2021 locations for 1950–2021, as well as 2021 location quintile and reference SDI quintile values.由健康指标与评估研究所（Institute for Health Metrics and Evaluation, IHME）统筹的2021年全球疾病负担研究（Global Burden of Disease Study 2021, GBD 2021），针对204个国家、地区及选定的次国家区域，估算了疾病、损伤与各类风险因素对应的疾病负担。社会人口指数（Socio-demographic Index, SDI）由GBD研究团队开发，用于辅助生成上述估算结果，是与健康结局密切相关的综合发展水平指标。该指数为三类0至1标准化指数的几何平均值：25岁以下总生育率（total fertility rate under the age of 25, TFU25）、15岁及以上人群平均受教育年限（mean education for those ages 15 and older, EDU15+）以及人均滞后分布收入（lag distributed income, LDI）。作为综合衡量指标，SDI取值为0的区域理论上处于与健康相关的最低发展水平，而SDI取值为1的区域则达到理论最高发展水平。本数据集包含1950年至2021年间所有GBD 2021估算区域的SDI数值表格，同时提供2021年各区域SDI五分位数及参照SDI五分位数数值。

背景概述

该数据集是2021年全球疾病负担研究（GBD 2021）的社会人口指数（SDI）数据，覆盖1950年至2021年全球204个国家和地区及部分次国家地区。SDI是一个综合发展指标，由生育率、教育和收入三个维度计算得出，用于评估与健康相关的发展水平。数据集包括历史SDI值和2021年的五分位分类，为健康研究和政策分析提供关键参考。
