Global Child Growth Failure Geospatial Estimates 2000-2019

"Annual estimates were produced for child growth failure (CGF) among children younger than 5 years of age at the 5x5 km-level for 105 low- and middle-income countries (LMICs) between 2000 and 2019. These estimates were produced using geo-positioned data from 460 household surveys, including the Demographic and Health Survey (DHS), Multiple Indicator Cluster Survey (MICS), and other country‐specific surveys. Countries and subnational units outside of these 105 LMICs were supplemented with GBD results.

This dataset includes the following:

- GeoTIFF raster files for pixel-level estimates for 105 LMICs
- CSV files of aggregated estimates for 195 countries at the national level, 105 LMICs plus GBD subnational locations at the admin 1 level, and 105 LMICs at the admin 2 level
- Code files used to generate the estimates"

2000年至2019年期间，本研究针对105个低收入和中等收入国家（low- and middle-income countries, LMICs）内5岁以下儿童的儿童生长发育障碍（child growth failure, CGF）情况，完成了5×5公里分辨率尺度下的年度估算。本次估算基于460项家庭调查的地理定位数据生成，这些调查涵盖人口与健康调查（Demographic and Health Survey, DHS）、多指标类集调查（Multiple Indicator Cluster Survey, MICS）以及其他国家专属调查。对于上述105个低收入和中等收入国家之外的国家及次国家级单元，本研究补充采用了全球疾病负担研究（Global Burden of Disease, GBD）的相关结果。

本数据集包含以下内容：
- 包含105个低收入和中等收入国家像素级估算结果的GeoTIFF栅格文件
- 三类聚合估算结果的CSV文件：分别为195个国家的国家级聚合估算数据、105个低收入和中等收入国家外加全球疾病负担研究次国家级行政一级单元的聚合估算数据，以及105个低收入和中等收入国家行政二级单元的聚合估算数据
- 用于生成上述全部估算结果的代码文件
