in the Middle East
The reliability of a survey depends on the unbiased and sensible selection of respondents.
In the absence of a granular census, Masae was asked to select the best locations to conduct household interviews in Iraq.
The client wanted Masae to sample accurate locations falling on dwellings, in both urban and rural areas, weighted by population densities at country level.
Masae leveraged satellite-derived data: High-resolution built-up presence probability layer from Sentinel-2 images and high-resolution population density estimates
This data was used to partition sampled administrative units in smaller iso-population enumeration areas based on spatial population distribution. Then target locations were sampled in each enumeration area, using built-up presence probability density
