For the record there are several regions, most with many many categories (some rather sad ones from the NA list: "venture capital", "social media", "retail and e-commerce", and "marketing and advertising"). There were 1230 total people on the global lists this year. Of course Forbes can't really defend itself because the notion of a "twelve hundred under 30" damages the pay-to-play golden goose. I would recommend poking around the list if you ever want a mood lightener. There are a truly comical number of people whose bio reads: "co-founder (CEO is over 30) of AI powered yadada which has raised $3M from investors". I think the median 30u30 business actually has considerably less revenue than a typical convenience store.
