Once the census and biophysical datasets are integrated, ELL welfare estimates can
be improved (see for instance. Mistiaen et al. 2002 for Madagascar). The preliminary
poverty estimates for rural Uganda control for spatial autocorrelation solely by relying
on Population Sampling Unit (PSU) means calculated from the census. By controlling for biophysical characteristics of the estimation procedure, the efficiency of the derived poverty estimates may be improved, leading to more precise estimates and enhancing the level of spatial disaggregation that is attainable.
