The Rothschilds are a large, wealthy family, and as you say, have accumulated their fortunes since the 1800s. The family has been involved in business for more than a century). Years ago when the number of billionaires start to soar, we made the decision to focus on individual wealth. We list brothers together, only if they are worth an estimated $1 billion apiece or $2 billion-plus total. We list a man, with his wife and children, if he’s the founder who built the fortune, even if he’s passed on some shares. But otherwise we really try to keep it focused on individuals. (Those fortunes with some nuclear family sharing are denoted with & family). That is why the family is not on, but Nat Rothschild, who has a personal fortune we can trace, is among the billionaires.
