From Prince William and Kate Middleton's royal bundle of joy — third in line of succession to the British throne — to 98-year-old David Rockefeller, the oldest billionaire alive, it's evident that authority transcends shape, size, and age.
Power is, in fact, relative to a person's capacity to enact change or direct the behavior of others when compared to his or her peer's ability to do the same.
In creating this list, we considered three criteria to determine power. A person's sphere of influence was the greatest indicator, followed by potential for acquiring future power, and estimated net worth. If two candidates of the same age seemed equally powerful, their net worth served as the deciding factor.
Now it's time to meet the most powerful people in politics, tech, finance, entertainment, sports, retail, and culture, ages 0 to 100.
AGE 0: Prince George of Cambridge
Son of Prince William and Catherine, Duchess of Cambridge
What makes him powerful: After his grandfather and father, the royal bundle of joy is third in line to succeed his great-grandmother, Queen Elizabeth II. In April, the 8-month-old embarked on his first royal tour, a 19-day visit to New Zealand and Australia.
AGE 1: Margaret Laura “Mila” Hager
Granddaughter of former President George W. Bush
What makes her powerful: The younger twin daughter of Laura and George W. Bush, Jenna Bush Hager and her husband, Henry Hager, gave birth last year to their first child, Margaret Laura Hager. Little "Mila" joins the Bush family as the first granddaughter — and great-granddaughter — to two former U.S. presidents.
AGE 2: Blue Ivy Carter
Daughter of Beyoncé and Jay Z
What makes her powerful: Blue Ivy — a name her parents tried (unsuccessfully) to trademark — is the offspring of hip-hop and pop's two biggest moguls. She's already a fashion trendsetter, world traveler, and recording artist, having appeared on Jay Z's song "Glory" and Queen Bey's song "Blue."
