Abstract:
The Global Subnational Infant Mortality Rates consists of estimates of infant mortality rates for the year 2000. The infant mortality rate for a region or country is defined as the number of children who die before their first birthday for every 1,000 live births. The data products include a shapefile (vector data) of rates, grids (raster data) of rates (per 10,000 live births in order to preserve
... precision in integer format), births (the rate denominator) and deaths (the rate numerator), and a tabular dataset of the same and associated data. Over 10,000 national and subnational units are represented in the tabular and grid datasets, while the shapefile uses approximately 1,000 units in order to protect the intellectual property of source datasets for Brazil, China, and Mexico. This dataset is produced by the Columbia University Center for International Earth Science Information Network (CIESIN).
The data in ESRI Shapefile (SHP), Microsoft Excel (XLS), American Standard Code for Information Interchange (ASCII) Grid formats and maps in Portable Document (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
