Where is the world's most Instagrammed place?
Popular photo-sharing app Instagram has now reached 400 million active users, clocking up its latest 100m members in just nine months, owner Facebook has announced.
More than half of the 100 million new users come from Europe or Asia, said Facebook, which bought the San Francisco-based firm for $1bn (£669m) in 2012.
The site has attracted celebrities including David Beckham and Caitlyn Jenner, and sees more than 80 million images shared every day.
Here's a snapshot of the figures involved.
