About these numbers
Counts cover the people on the public page for each September date, every one traced to a Wikidata record. Billionaires need a dated estimate of at least $1B from Forbes, Bloomberg, the Sunday Times Rich List, Hurun or a filing; combined wealth adds the low end of those estimates, the newest as of September 2026. Month ranks compare all twelve months on the dataset built on 2026-09-28. Read the methodology.
