What this guide establishes
- The analysis compares aggregate brackets, not individual merit or conduct.
- Total-asset concentration and the mix of real estate, deposits and securities are calculated separately.
- Values describe records at their disclosure dates, not present wealth or investment performance.

Bracket shares describe this disclosure sample. They do not measure investment returns, liquidity, conduct or present ownership.
One representative current record per person
The report uses one representative row for each person in the latest records included by PWRMAP. Historical rows are not added together. The sample size and data-through date update when new verified records are published.
Records are ordered by disclosed total assets, then divided into the top 1%, 5% and 10%. Boundary counts may move slightly as the dataset changes.
Concentration and asset composition answer different questions
Concentration divides each bracket's disclosed total by the full sample total. Composition instead uses positive reported amounts for real estate, deposits, securities and vehicles. Debt is shown separately because it affects the net total differently.
The results are a way to form better research questions. They do not explain acquisition history, current ownership, returns or whether any holding is appropriate.
