We call them pavements in the UK and I kinda think sidewalk is more descriptive. You walk on the side of the road.
In the US basically anything paved is pavement.
Asphalt road: Pavement
Concrete sidewalk: Pavement
Giant parking lot: Pavement
Gravel road: Believe it or not - paveme… well that one’s debatable.
I’d say gravel roads can be argued to be “paved” if it’s really fine gravel that has been properly packed down by repeated driving on it, to the point where it starts looking shiny and sort of like glazed clay
Footpath makes it sound like it goes through the woods or a field or something.
