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.

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.

Son of Google co-founder Sergey Brin
What makes him powerful: Benji Brin, the son of one of the most notable names in tech, reportedly had a domain name just days after he was born.

AGE 6: Ella Gordon
Daughter of Jeff Gordon
What makes her powerful: The list of legacy racing families — which includes Earnhardt, Andretti, Petty, and Unsder — might soon add the Gordon clan.

One of the highest-paid YouTube stars
What makes him powerful: At just 7 years old, Evan is the 20th-highest-paid YouTube star, earning up to an estimated $1.32 million yearly income after YouTube’s 45% cut.

Another powerful 12-year-old: First Daughter Sasha Obama will decide where the first family lives after leaving the White House.
AGE 13: Viraj Puri
What makes him powerful: The Virginia middle-school student started his bullying-prevention blog to “use technology to bring lawmakers and teens together.” Bullyvention is not just a place anyone can speak out against bullying: It’s also a tool that can be used to locate cyberbullying as it’s happening around the country through a heat map that Puri created to track and record bullying patterns. Puri’s is now the first website to team up with the U.S. House of Representatives’ Congressional Anti-Bullying Caucus.
AGE 14: Daniel Singer
What makes him powerful: This Zuckerberg-to-be is barely a teenager and already lords over a mini tech empire. He’s the creator of a website called YouTell, launched in 2012 and built with the help of one of his dad’s programmer friends. The site lets Facebook friends talk anonymously to one another, and has become popular with Singer’s age group.
YouTell landed him two patents, five employees, 3.1 million users, and $200,000 of seed funding, which allowed him to expand into the app market with Backdoor (iOS) and Backchat (Android).

Daughter of President Barack Obama
What makes her powerful: Obama’s daughter accompanied her mother and younger sister on a trip to China last month where she met with President Xi Jinping and his wife, Peng Liyuan. Not only was the trip a notable foreign-policy move — it was also a notable fashion move.

AGE 16: Malala Yousafzai
Women’s education activist
What makes her powerful: Yousafzai is a young Pakistani student who survived an assassination attempt by the Taliban. Her refusal to stand down from what she believed was right has brought to light the plight of millions of children around the world who are denied an education.

AGE 17: Lorde
Grammy Award-winning music artist

The youngest to hit No. 1 on the Billboard Hot 100 chart in 26 years, Lorde took home two major awards at this year’s Grammys.
AGE 18: Bethany Mota
What makes her powerful: A social-media goddess and ascendant fashion icon, Mota has turned her YouTube channel into a full-blown career and “celebridom.” Her most popular channel features makeup tutorials, DIY, and “haul videos” in which she shows off her most recent shopping finds.
The teen-apparel fixture has more Instagram followers than Vogue, Elle, Marie Claire, Glamour, and Cosmopolitan combined, as well as a clothing and jewelry line at Aéropostale. Several sources familiar with YouTube advertising suggest she’s pulling down $40,000 a month from her videos alone.
AGE 19: Andrew Wiggins

Small forward for the University of Kansas Jayhawks
What makes him powerful: People call Andrew Wiggins, the small forward for the Kansas Jayhawks, the next LeBron James. And while his team lost to Stanford during the NCAA tournament, the 6-foot-8-inch Canadian with a sweet slam-dunk is considered the best player in the loaded 2014 NBA draft.
AGE 20: Justin Bieber
Grammy Award-winning musical artist
What makes him powerful: Over the past year, the Bieb’s reputation has taken quite the tumble, thanks to a string of fights with paparazzi, pot-smoking allegations, and a DUI arrest. Still, Bieber has a net worth of $58 million and is the second-most-popular celebrity on Twitter, with more than 50 million followers. He’s being heralded for his marketing genius for updating his squeaky clean image to attract an older and broader fan base.
AGE 21: Palmer Luckey
USA Today video
Inventor of the Oculus Rift
What makes him powerful: Luckey is the founder of Oculus VR, a startup that makes virtual-reality headsets such as the Oculus Rift.

AGE 22: Neymar da Silva Santos Júnior
Jamie McDonald/Getty Images
What makes him powerful: No other player in the 2014 World Cup will be under as much scrutiny as Neymar da Silva Santos Júnior — known around the world simply as Neymar — a forward for Spanish club FC Barcelona and the Brazilian national team.He’s proved he can handle the pressure in international competition, winning the Golden Ball award as MVP in the 2013 Confederations Cup.
While Neymar has had trouble finding his footing at Barcelona, on a team that already features Lionel Messi, he still earns 3.8 million pounds per goal.
AGE 23: Evan Spiegel
CEO of Snapchat
What makes him powerful: As the creator of an app with 70 million usersaround the world, Spiegel is a dominant force in tech. He faced some backlash when he decided not to apologize for an information security breach, but the tech world waits patiently to see what his next move will be after turning down a $3 billion offer from Facebook.
Other powerful 23-year-olds: Magnus Carlsen of Norway won the world chess championship in November and ushered in a new era of the game. Jennifer Lawrence still commands the screen as the lead in the successful “Hunger Games” franchise.
AGE 24: Taylor Swift
Grammy Award-winning musical artist
What makes her powerful: Swift may have gone home empty-handed from this year’s Grammy Awards, but she’s still thehighest-paid singer. She topped Billboard’s list for the second year in a row by bringing in nearly $40 million, crushing it with merchandising, branding, and perhaps the best metric of fan passion: touring. Her sweet-spot demo captures revenue from every angle, while her global Red Tour put an estimated $30 million in her pocket.
AGE 25: Kevin Durant
Jamie McDonald/Getty Images
Forward for the Oklahoma City Thunder
What makes him powerful: The nextpresumed NBA MVP scores about 20 shots a game and leads his team to impressive victories. Even LeBron has voiced jealousy of the 6-foot-9-inch forward’s skills. People talk about the vast expanse of his arms (whichspan over 7 feet when outstretched), his quick release, and his superhuman-like hand-eye coordination, all of which make him a force to be reckoned with.
Another powerful 25-year-old: Inbee Park has been ranked No. 1 in the Women’s World Golf Rankings for almost an entire year.
AGE 26: Lionel Messi
David Ramos/Getty Images
What makes him powerful: In the battle for maestro of La Liga, Messi might fall short of Cristiano Ronaldo in total goals scored this season, but the FC Barcelona and Argentina national team forward does seem to set records every time he sets foot on the pitch. He became the youngest player to score 200 league goals in Spain at 25, has scored against 100 goalkeepers, and nets a goal every 78 minutes, ahead of Sergio Aguero, Luis Suarez, and Ronaldo.
Despite his numerous club titles, some say he needs to win the World Cup with Argentina to cement his place among all-time greats such as Diego Maradona and Pelé.
AGE 27: David Karp
Mario Tama, Getty Images
CEO of Tumblr
What makes him powerful: Karp’s unnaturally accelerated success with Tumblr completely negates the fact that he didn’t even finish traditional high school. Yahoo paid $1.1 billion in cash for his company last year, and Karp remains CEO. Karp ranked No. 2 on Business Insider’s 2013 Silicon Alley 100 list.
AGE 28: Lady Gaga
Grammy Award-winning musician
What makes her powerful: The Mother Monster beat chart-topping artists such as Rihanna, Justin Bieber, and Taylor Swift to become the second-highest-paid musician. Lady Gaga reeled in $80 million last year, a figure that would have been higher had an injury not cut her Born This Way Ball Tour short.
She’s an outspoken advocate for LGBT equality, marching in Pride parades and launching a nonprofit anti-bullying organization.
AGE 29: Mark Zuckerberg
CEO of Facebook
What makes him powerful: He’s built the largest social network ever, with over 1 billion users, and from WhatsApp to Oculus VR, Zuckerberg has overseen a number of huge Facebook acquisitions in the past year. Now the Zuck has the ear of the White House: He recently took a trip to Washington after calling President Obama to express “frustration over the damage the government is creating for all of our future.” He was subsequently invited to chat with other tech powerfuls about privacy and intelligence in technology.
Another powerful 29-year-old: LeBron James took the NBA championship and was named the NBA and Finals MVP for the second year in a row.
AGE 30: Edward Snowden
Former National Security Agency systems analyst
What makes him powerful: Snowden, a Nobel Peace Prize nominee, perpetrated one of the greatest intelligence leaks in U.S. history. Last May, Snowden snuck as many as 200,000 classified documents out of an NSA facility, fled to Hong Kong, and distributed documents to journalists. The collection — which includes NSA intelligence reports, spying requests from other U.S. government agencies, and information on the mass surveillance of citizens — disrupted American ties with allies and benefited adversaries.
AGE 31: Kim Jong-un
Supreme leader of North Korea
What makes him powerful: Last month, North Korea claimed that voters in the country unanimously re-elected supreme leader Kim Jong-un. He isn’t the most favorably viewed leader in the world, but it’s hard to deny his influence. He can snap his fingers and have anyone — be it family or North Korean officials — executed. And he gets Dennis Rodman to sing him “Happy Birthday.”
AGE 32: Beyoncé

Grammy Award-winning musician
What makes her powerful: Queen Bey is the third-most-honored woman in Grammy history, claiming 17 wins and 46 nominations. While some say her sexual empowerment is a far cry from feminism, others laud her songs like “Run The World (Girls)” for wearing the label proudly. She’s half of the highest-earning celebrity couple— she and music-mogul husband Jay Z took home $95 million last year.
Another powerful 32-year-old: Kate Middleton, aka the Duchess of Cambridge, gave birth to the heir to the British throne in July 2013.
AGE 33: Daniel Schwartz

AGE 34: Chelsea Clinton

AGE 35: Kobe Bryant
Point guard for the Los Angeles Lakers
What makes him powerful: Last year, at 34, Kobe became the youngest player in NBA history to reach 30,000 career points. A torn Achilles tendon took him out of the game over the summer, but he was back on the court in December. He has been calledthe hardest-working player in the NBA.
AGE 36: Kanye West

Grammy Award-winning musical artist
What makes him powerful: Kanye has been compared to Steve Jobs, Picasso, Michael Jordan, Jimi Hendrix, and evenGod — of course Yeezy drew those comparisons himself. His sixth studio album, “Yeezus,” was certified gold less than two months after release, later went platinum, and inspired a film coming to theaters.
Kanye makes the list because, as radical and self-indulgent as he is, all of America tunes in to hear what he has to say.
AGE 37: Floyd Mayweather Jr.
What makes him powerful: Floyd Mayweather Jr. is the highest-earning athlete in the world — once pocketing $40 million for a single fight — and with homes, cars, and an impressive shoe collection, he knows exactly how he wants to spend his paychecks. He’s also undefeated: In 45 career matches, Mayweather hasn’t lost a fight yet.
AGE 38: Marissa Mayer
CEO of Yahoo
What makes her powerful: This former Googler is proof you can teach old dogs — like aging Internet giant Yahoo — new tricks. In her two years since taking the reins, she got a redesign to go through, put mobile first (and meant it), and acquired an insane number of companies. Called a “destroyer of startups,” Mayer has ransacked Silicon Valley to cobble together a younger, hipper team at Yahoo.
AGE 39: Leonardo DiCaprio
Golden Globe-winning actor
What makes him powerful: The recent Golden Globe winner saw monstrous box-office success with “The Great Gatsby” and “The Wolf of Wall Street.” His portrayal of financial scumbag Jordan Belfort won DiCaprio some of the best reviews of his career. He has yet to win an Oscar, but DiCaprio continues to make movies that everyone wants to see simply because he’s in them.
AGE 40: Sergey Brin
Co-founder and director of special projects at Google
What makes him powerful: Larry Page’s “other half” is responsible for trying to decide which ideas Google will pursue. He oversees Google X’s “moon shots,” the hush-hush long-term projects that try to tackle big problems — think Google Glass, driverless cars, smart contacts for diabetics, and flying wind turbines that generate power.
Google recently carried out its plan to split its stock, consolidating the voting power of executives Brin, Page, and executive chairman Eric Schmidt.
AGE 41: Larry Page
CEO and co-founder of Google
What makes him powerful: When Page took over as Google’s CEO, he wanted to reinvigorate the company’s vision. Today, the company continues to dominate search, makes a ton of money with ads, and is leading a number of other innovative projects, including Google Glass. In the last year or so Google generated nearly $18 billion in profits — money that Page will be able to use to forward his grand visions for granting Internet access to the world.
AGE 42: Elon Musk
CEO of Tesla and Space X
What makes him powerful: Arguably the greatest inventor alive, Elon Musk steered three revolutionary companies to monstrous success, while his ownfortune more than tripled in the last year. Tesla’s on a fast and furious quest to disrupt the auto industry, with plans underway to build a massive Gigafactory. SpaceX launched the first commercial satellite into orbit and is under agreement with NASA to resupply the International Space Station.
Musk, who made his fortune co-founding PayPal, was the inspiration for Tony Stark’s character in “Iron Man.”
AGE 43: Ted Cruz
What makes him powerful: In a short time Ted Cruz went from being the GOP’s ultimate conservative purist to one of the most despised men in the U.S. Senate,provoking the federal government shutdownlast year. Still, the Tea Party rep has made an impression with his take-no-prisoners and make-no-compromises approach to legislating. He staged a 21-hour faux filibuster to defund Obamacare. He failed then, but recently had his bill to bar Iran’s U.N. envoy from entering the U.S. pass in the Senate, a tidy win for the Texas freshman minority senator.
AGE 44: Paul Ryan
What makes him powerful: The 2012 Republican vice presidential nominee has become a powerful member of Congress. Currently chair of the House Budget Committee, he recently unveiled the House Republican budget, which would cut government spending by $1.5 trillion over the next 10 years and repeal the Affordable Care Act.
He’s also the clear front-runner to successor Rep. Dave Camp as chairman of the powerful Ways and Means Committee, where he would be in charge of policies governing Medicare, Medicaid, Social Security, and more.
Another powerful 45-year-old: “Lean In” author Sheryl Sandberg is credited with bringing adult supervision to Facebook and is one of the world’s first self-made billionaire women.
AGE 45: Robin Li
CEO of Baidu
What makes him powerful: Money is power, and Robin Li has a lot of both. With an estimated net worth of $12.1 billion, he’s one of the richest people in tech. And as the CEO of China’s top search engine, Li’s like the Larry Page of Asia. According to Bloomberg, Li said in October that his company would invest even more aggressively in mobile search; installments of its search app rose to 330 million users — an increase of 50% — from June to September.
AGE 46: Peter Thiel

Venture capitalist and co-founder of Palantir Technologies
What makes him powerful: Famous for being Facebook’s first investor, and co-founder and former CEO at PayPal, Thiel has another big winner with big-data consultancy Palantir Technologies. The semisecret firm has worked for the FBI and CIA, and raised $107.5 million in December.
Thiel’s name is synonymous with entrepreneurship. His venture firm Founders Fun helps power Airbnb, Practice Fusion, and payments company Stripe; and each year, Thiel gives 20 teenagers $100,000 to drop out of college and start a company.
AGE 47: Roman Abramovich

Russian businessman, oligarch, and owner of the Chelsea Football Club
What makes him powerful: Abramovich is one of the richest men in Russia and the world, worth more than $9 billion. He wasorphaned as a child and today lives a luxurious lifestyle full of superyachts, commercial airplanes, getaway homes all over the world, and a friendship with Vladimir Putin. Abramovich’s stake in steel company Evraz lost about two-thirds of its value in 2013, but he continues to do business in metals.
Another powerful 47-year-old: Recently appointed Walmart CEO Doug McMillon runs the No. 1 company in the 2013 Fortune 500.
AGE 48: J.K. Rowling
Best-selling author of the Harry Potter series
What makes her powerful: Rowling, who ignited a new generation of readers with her magical series, became the first billionaire author. She’s still cashing in on the boy wizard 17 years later. In an unprecedented move, she retained the digital rights to her novels, rather than signing them over to her publisher, and launched an online store so she can sell the e-books directly to consumers. The Pottermore site allows Rowling to reap 100% of everything she sells.
It was recently announced that Rowling’s spinoff book, “Fantastic Beasts and Where to Find Them,” would be turned into three movies.
AGE 49: Jack Ma
Executive chairman of Alibaba Group
What makes him powerful: No. 146 on Forbes’ billionaires list, Jack Ma created the largest e-commerce business in China. Ma made headlines a couple of years ago withtalks of buying Yahoo, but he’s going to have his own plate pretty full very soon. His company’s impending IPO could exceed $150 billion, making it the world’s largest this year, if it happens.
AGE 50: Jeff Bezos
David Ryder/Getty Images
CEO of Amazon
What makes him powerful: Amazon seems to be stretching into new frontiers every few weeks, from its drones program to its quest to dominate mobile payments. The e-commerce giant has been making a lot of moves in hardware lately, with Fire TV and an upcoming smartphone that will let you see 3-D images without wearing special glasses.
Bezos puzzled everyone when he scooped up The Washington Post last August, but he has some pretty shrewd plans for saving the paper.
Disclosure: Jeff Bezos is an investor in Business Insider through his personal investment company Bezos Expeditions.
