Table 1 Average annual household energy expenditures, incomes, net incomes, Nhs, and Ebs portrayed for different income groups based on their relationship to AMI. Note that the statistics for Eb and Nh are calculated per cohort after averaging the income and expenditure statistics to avoid the effect of extreme values skewing the interpretability of these metrics as described in the text. For example, the actual weighted average Eb for households from 0-30% AMI is 16,451%, and the average Nh for this cohort is 8.6 due to subsets of the dataset with very low incomes or low energy expenditures. Nh is not as susceptible to this skewing effect.
