It’s something that we all knew but perhaps didn’t fully appreciate—just about all of us have cell phones now, and we use them a lot.

According to new figures published by the International Telecommunications Union on Thursday, the global population has purchased 6 billion cellphone subscriptions. Fully a third of those, for a total of two billion, are from China and India.

As smartphone prices continue to fall, and more people have access to other data devices, the ITU also reported mobile broadband continues to rapidly grow.

“Over the past year, growth in mobile-broadband services continued at 40 percent globally and 78 percent in developing countries,” the ITU said in a statement. “There are now twice as many mobile-broadband subscriptions as fixed-broadband subscriptions worldwide.”

The ITU ranked South Korea again as the world’s “most advanced ICT economy,” adding that the average price of home Internet access has fallen 75 percent globally between 2008 and 2011, primarily in the developing world.

CTIA, the industry group for all wireless providers in America, also reported Thursday that between July 2011 and June 2012, Americans used 1.1 billion gigabytes of mobile data—an increase of 104 percent from the previous period.

The trade group reports there are more mobile phone subscriptions (322 million) than there are Americans (314 million). Of that total, 41 percent are smartphones, and 23 percent are prepaid customers.

Here in the United States, the CTIA says, Americans collectively spent 2.321 trillion minutes on the phone over the last year (a three percent increase over last year), and sent just about as many texts: 2.273 trillion (also an increase of three percent.)

One last figure that might give you pause: the average monthly cell phone bill has fallen slightly to $47.16—meaning each of us, on average, spends $566 per year on our phones.
