(8,710 posts)your 18% estimate is way, way off.
Estimated 2016 U.S. population: 322,464,620
Population of states represented by two Democratic Senators or Democrat/Independent: 139,864,970 (43.47%)
Population of states represented by two Republican Senators: 105,621,918 (32.75%)
Population of states represented by split parties (Rep/Dem or Rep/Ind): 76,977,732 (23.87%)
So you are correct that there is a disparity between state populations as a percentage of national population and Senatorial representation, but it is nowhere near the 18% figure.
Edited to add: I just realized that when you use the 52% figure, you weren't talking about the current Senate makeup, but rather the aggregate. So in that sense, yes, it about 18% (17.66%, to be exact for 2016 figures). Apologies for misunderstanding.
