Component 1 – the Gini-Index – serves as a weighting factor for component 2 (private consumption); therefore it is the only index coloured in grey. Components 6, 16, and 17 can either be positive or negative, thereby increasing or decreasing the total value of NWI.
The NWI consists of twenty components that are aggregated in the following way:
