In order to assess the overall degree of human exclusion throughout the life cycle, we aggregate the levels of exclusion in each of the six dimensions. Using a simple arithmetic sum, the overall level of exclusion can therefore be defined as: $$HEx^{v}=dEx^{Nm}+dEx^{ChM}+dEx^{Lr}+dEx^{Yu}+dEx^{Np}+dEx^{Le}$$ As each indicator has a value ranging between 0 and 1, the overall score will take a value between 0 <$HEx^{v}$ <6, reflecting the degree of exclusion of an individual throughout his or her life cycle. The total value of the Index will therefore represent an absolute value of exclusion, reflecting the likelihood of an individual to be excluded from the six dimensions of development described above. In the case of missing values in one of the dimensions, an expansion factor will be applied to facilitate the computation of the index. Missing information for two or more dimensions will not allow proper assessment of exclusion, hence the need to eliminate the country concerned from the exercise.

Estimations at sub-national levels and across time

The same conceptual and methodology frameworks can be applied to assess levels of exclusion at sub-national levels and over different periods of time. Data can be used at different tiers of government to estimate exclusion across subregions. The approach can also be used with longitudinal data sets to identify the drivers of exclusion across time and for each subregion. The outcomes of this exercise will provide critical information on the drivers of exclusion and the type of policies that have contributed to reduce or increase exclusion over time and across subregions.

Exclusion between subgroups of population

Similarly, the Index can be applied across gender as well as urban and rural settings. Maintaining the same decomposition in six dimensions, this method allows for a cross-sectional analysis of exclusion between groups, helping identify the gaps and the factors of exclusion for each subgroup of population, as described in the report.
