Notes
Hardship Measurement Model (HARD)
Where data were available in the World Development Indicators (WDI), the variables above were used to construct three independent components that explain 97.7% of the variation in the indicators.
The first component, HARD1, explained 75% of the variation and was a relatively equal weighting of all the indicators. The second independent component, HARD2, explaining about 20% of the variation, and was a complex Inequality-Male Infant Mortality-Unemployment, Household Expenditure historical controller. The third independent component, HARD3, was a Family Work-Inequality-Male Infant Mortality historical controller that explained 3% of the remaining variation for a total of 97.7% of the variance explained using Principal Components Analysis (PCA).
From the time plots, all the components were stabilizing by 2014.
