The answer

60,000,000 people

Roughly 60M.

Historians estimate 60 to 70 million people under Roman rule around 150 CE — somewhere near a fifth of everyone alive at the time. The city of Rome itself is thought to have passed a million residents, a level no European city reached again until London in the 1800s.
