GA, you disappoint me. Linking data describing Western Europe and claiming to refer to population you when you were explicitly quoted saying Europe and using the term landmass (highlighted in my other post) does not befit a person of your meticulousness. Thus...

Europe (pronounced /ˈjɜrəp/, /ˈjʊərəp/) is, by convention, one of the world's seven traditional continents. It covers roughly 10,180,000 km² (3,930,000 sq mi) of Earth's surface.

The United States of America (commonly referred to as the United States, the U.S., the USA, or America) has a land area of about 9,158,960 km² (3,536,294 sq mi).

Consider yourself generalized.
