Geography reflects each issuer's registered business address per SEC EDGAR filings where available, falling back to the exchange or listing where no SEC filing exists — not necessarily where a company's stock is primarily listed (e.g. TSMC is classified as Taiwan even though its ADR trades on the NYSE).
