Almost as many people use Facebook as live in the entire country of China

If Facebook were a country, its population would rival the single most populous country on Earth. That’s one eye-popping takeaway from Facebook’s Q3 earnings report, in which the site announced that its monthly active users cleared 1.35 billion -- roughly equal the population of China, and 9 percent larger than that of India. By these numbers, nearly 20 percent of the world’s population logs into Facebook once a month. And if we just look at the world’s Internet users, roughly half of them -- every other person with Internet on the planet -- use the site actively.
