Table 1: Census based Approach

Incorrect size measures have also been used as MOS to demonstrate the
impact on the different estimates. The bigger the relationship with the target
value, the larger is the impact of size on the MSE (in percent).
Stratification has been applied by different variables as described in the
appendix.
1.1. Sampling from a purely satellite based sampling frame, where the
population values are derived from a raster of gridded population data.
There are situations, where there is no frame at all. In this case the option
exist to use gridded population data. In our simulation we have used
WorldPop, and results are shown bellow.
