Every person on the English Wikipedia, sliced by where and when they were born, their gender, and what they did. The underlying database has ~1.9 million people and is built straight from Wikidata. Birth years are capped at 1500–2010 — earlier data is patchy, later cohorts are mostly too young to be Wikipedia-notable yet.
You can fool all the people all of the time if the advertising is right and the budget is big enough.
