The German Capability Index—An Operationalization of Sen’s …
183
The analysis so far has revealed heterogeneity in the capability budget across the
household groups and their respective justice spreads. Hence, the different effects
will now be summarized in the capability index for the various German household
groups based on the equations of Sect. 4.2.
4.4 Revealed Capabilities
The analysis reflects the heterogeneous picture of the German capability index (GCI)
for the various households (Table 14). The GCI measures the distribution of the
capability budgets between the social groups and their functionings.
Our results reveal a great spread between the social groups over all functionings.
The highest GCI is calculated for the group of single women and single men (0.469,
0.458), followed by the group of couples (0.376), and at a much lower level the
single parents (0.274) as well as couples with children (0.164). These numbers result
in an aggregated GCI for the average household of 0.248. The capability budget of
the single parents and of the couples with children is smaller than that of the single
households. Essentially this implicates that a single woman or a single man can make
much better use of their functionings than members of the other household groups.
