Each modeled surfaces is produced using standardized geostatistical methods, publically available DHS data, and a standardized set of covariates across countries. Each map package contains a mean estimate surface, an uncertainty surface, and corresponding information on the model creation process and validation. Not all indicators are available for all countries, a table summarizing the data available at the time of visit is available for download by clicking the Data Availability button. For more information on the modeling methods, refer to Spatial Analysis Report 11. For more information on the use of these surfaces in decision making, refer to Spatial Analysis Report 14.
