By definition, the US is <b>the</b> First World Country.<br>Maybe other industrialised nations should lean away from labelling themselves first-world countries.,(reply>), 1st, 2nd, and 3rd world countries is most often credited to Alfred Sauvy, French demographer. It was a way to label the western allies as superior to the 2nd world communist block. Any other country  not a apart of the western allies or communist block was labeled 3rd world. It honestly holds no value to label a country one way or the other. It was simply political bickering and banter of the Cold War.
