Places with more than 10 million residents — known as megacities — are becoming more common as people from rural areas migrate to urban ones.

Why it matters: The benefits of megacities — which include opportunities for upward mobility and higher wages — can be offset by their negatives, like the fact that they're breeding grounds for COVID-19.

What's happening: Urbanization is proceeding rapidly, with more than half of the world's population now living in cities, according to Visual Capitalist, an online publisher aimed at investors.

  • Cities like Delhi and Shanghai are growing particularly fast.
  • Tokyo — population 37 million — has the most people, but declining birth rates and an aging population could mean that Delhi surpasses it by 2028.
  • By 2035, Bangalore (India) and Lahore (Pakistan) are expected to replace Tianjin (China) and Buenos Aires (Argentina) in the top 20 list, Visual Capitalist said.

Where it stands: The U.S. has two megacities — New York and Los Angeles — but only New York cracked the global top 20, according to Macrotrends, a research platform for investors that published side-by-side rankings of the most populous cities in the U.S. and the world.

  • Rounding out the top 10 in the U.S.: Chicago, Houston, Dallas-Fort Worth, Miami, Atlanta, Philadelphia, Washington, D.C., and Phoenix.

The bottom line: "The world is a crowded place, with human population expected to reach 9 billion by mid-century," says National Geographic, which published this fun interactive of major megacities.

Japan's Naomi Osaka lights Olympic cauldron, kicking off Tokyo Games

After a year-long delay, the Olympics finally got underway Friday as tennis star Naomi Osaka, who is competing for Japan, lit the cauldron, formally kicking off the Tokyo Games.

The big picture: Friday's opening ceremony looked, like many things over the last year, different than normal — multicolored seats replaced cheering fans, masks were a central part of the athletes' uniforms and a subdued, somber tone marked the occasion.

China sanctions Wilbur Ross, 5 other Americans over Hong Kong warnings

The Chinese government imposed sanctions on Monday against six Americans, including former Commerce Secretary Wilbur Ross, in response to an advisory from the Biden administration warning businesses of the increased risks of operating in Hong Kong.

Why it matters: It's the latest example of China responding furiously to U.S. attempts to shed light on human rights abuses in places like Hong Kong, Xinjiang and Tibet, which Chinese officials routinely condemn as "interference" in domestic affairs.

Cleveland Indians change name to "Guardians"

The Cleveland Indians baseball team announced Friday that it will change its name to the "Guardians," following years of activism and protests against a moniker considered offensive by many Native Americans.

Why it matters: It's the first time the team will change its name since 1915, a move that comes in the wake of the nationwide racial reckoning that began with the murder of George Floyd.
