Global Subnational Infant Mortality Rates, Version 2.01

The Global Subnational Infant Mortality Rates, Version 2.01 consist of Infant Mortality Rate (IMR) estimates for 234 countries and territories, 143 of which include subnational Units. The data are benchmarked to the year 2015 (Version 1 was benchmarked to the year 2000), and are drawn from national offices, Demographic and Health Surveys (DHS), Multiple Indicator Cluster Surveys (MICS), and other sources from 2006 to 2014. In addition to Infant Mortality Rates, Version 2.01 includes crude estimates of births and infant deaths, which could be aggregated or disaggregated to different geographies to calculate infant mortality rates at different scales or resolutions, where births are the rate denominator and infant deaths are the rate numerator. Boundary inputs are derived primarily from the Gridded Population of the World, Version 4 (GPWv4) data collection. National and subnational data are mapped to grid cells at a spatial resolution of 30 arc-seconds (~1 km) (Version 1 has a spatial resolution of 1/4 degree, ~28 km at the equator), allowing for easy integration with demographic, environmental, and other spatial data.

《全球地方级婴儿死亡率，版本2.01》包括对234个国家及地区的婴儿死亡率（IMR）估算，其中143个包括地方级单元。数据以2015年为基准（版本1以2000年为基准），并源于2006年至2014年间的国家办公室、人口与健康调查（DHS）、多指标集群调查（MICS）以及其他来源。除了婴儿死亡率之外，版本2.01还包含了出生和婴儿死亡率的粗略估算，这些数据可根据不同地理单元进行汇总或细分，以计算不同尺度或分辨率的婴儿死亡率，其中出生率为分母，婴儿死亡率为分子。边界输入主要来源于《全球人口网格，版本4》（GPWv4）数据集。国家和地方级数据被映射到30弧秒的网格单元中（相当于大约1公里），空间分辨率为30弧秒（相当于大约28公里，赤道附近），便于与人口、环境和其它空间数据进行整合。
