Documentation for the Global Subnational Infant Mortality Rates, Version 2

This document outlines the basic methodology and data sets used to construct the Global Subnational Infant Mortality Rates (IMR), Version 2, along with use cases, limitations, and use constraints. The second version of SEDAC’s Global Subnational Infant Mortality Rates data set compiles IMR data 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. Boundary inputs are derived primarily from the Gridded Population of the World, Version 4 (GPWv4). National and subnational data are mapped to grid cells at a spatial resolution of 30 arc-seconds (~1 km) allowing for easy integration with demographic, environmental, and other spatial data.
