The image here presented is part of the analysis of fuel poverty among French households as laid forth by Berry et al. (2016). Such an analysis on France's energy insecurity is further broken down by levels of energy vulnerability. The image at hand represents the different levels of energy insecurity according to the levels first presented in the definitional table of energy insecurity groups against the total number of income per unit of consumption.
