Here's the 2012 NEC definition:
Location, Damp. Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture. Examples of such locations include partially protected locations under canopies, marquees, roofed open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as some basements, some barns, and some coldstorage warehouses.
If a crawl space under the house with exposed earth as the floor can be considered a damp location
It certainly can be a damp location, but it really shouldn't be. I.e. if your crawl space sees enough water to be considered damp, that is definitely worth fixing. Most crawl spaces aren't damp.
