Outside the USA they're pretty ubiquitous so repairs and parts are easier to come by.
They are in theory more fuel efficient and people respond to those fuel efficiency numbers by buying them over automatics.
Better for dealing with road networks that weren't preplanned, which you see a lot of outside the USA. Since you can skip gears
Finally they're heavily normalised in many countries. Though this is less a reason to do so and more just a reality
In the UK for instance if you pass your driving test in an automatic you can only legally drive automatics. But pass it in a manual you can drive both. So people will generally just pass in a manual. Which means they're used to manuals and thus more likely to continue using manuals.
