GridSample is a tool to select clusters for household surveys using gridded population data.
This tool may be used when a gridded population dataset is more accurate than the census sample frame, the survey design calls for spatial oversampling to improve small area estimates, or when custom-sized clusters are needed
With the GridSample tool, you can design and implement household surveys from gridded population estimates in low- and middle-income countries.
