Typical household gain in local currency
Because each wealth tier is itself a power-law (Pareto) distribution, the mean per-household figure overstates what a typical household in the tier received — especially at the top, where a handful of ultra-high-net-worth individuals pull the mean far above the majority of the tier's members. Each figure below shows the median household within the tier, not the mean. The within-tier correction factor (rightmost column) shows how far the mean overstates the typical.
Correction factors (typical ÷ mean), derived from Pareto α = 1.161 (80/20 distribution): Bottom 80% = 86% · Next 16% = 86% · Next 3.2% = 83% · Next 0.64% = 56% · Top 0.01% = 29%. The top 0.01% correction is most dramatic: a billionaire at the 99.999th percentile pulls the mean to roughly 3.5× what the typical household in that tier actually received.
