Although the conventional wisdom might suggest that, say, U.S. presidents are more likely to be firstborns — they’re not. Actually,52 percent of presidents are middle children — a fact that takes into account older female siblings, which somehow hadn’t been included in previous data. Notable middles include Abraham Lincoln, John F. Kennedy and Donald Trump* as well as Winston Churchill, Bill Gates, Martin Luther King Jr., Warren Buffet, Madonna, Mart Twain, Mark Zuckerberg, Martha Stewart, Susan B. Anthony and Steve Forbes.
*As psychologist Catherine Salmontold CNN, “Donald Trump is a middle with a firstborn brother who didn't fit the role. Donald usurped it.”
