Errr, not in the rural area I grew up in. Gravel driveways are super common, gravel roads not so much.

To give some specifics: I only remember driving down an actual gravel road (like, for public use) a single time. In 18 years. Even my friends who lived >30min from the nearest "city" (~10k population) had paved roads all the way.

But that is just my own experience. Areas with a different climate or geography might be a totally different story. My hometown area is relatively flat, lots of farmland, and rarely gets severe winter weather.

FWIW in non-rural Canada we sometimes have gravel roads in towns twice that 10k size and in the metro area of a multi million inhabitant city (of which there are not all that many in Canada :)).

Not saying it's common. I don't have to drive over one of those but I have had to when there was construction on our regular route. It's right off the main road leading into town from the highway.

What most people mean by gravel road is macadamized road, which is a gravel/aggregate material bound in crowned layers from larger rocks to smaller on top often by a tar or asphalt binder or at least through compaction. There are true gravel roads in some rural areas, but, thankfully, I've rarely encountered them.
