Only 9% of America Chose Trumpand Clinton as the Nominees By ALICIA PARLAPIANO and ADAM PEARCE While Donald J. Trump or Hillary Clinton will represent the entire country, the Americans who selected them are a small part of it. The United States is home to 324 million people. Each square here represents 1 million people. 103 million of them are children, noncitizens or ineligible felons, and they do not have the right to vote. Estimates for ineligible felons are from 2010. 88 million eligible adults do not vote at all, even in general elections. Based on the share of eligible adults who voted in the 2012 general election. An additional 73 million did not vote in the primaries this year, but will most likely vote in the general election. Does not include people who voted in caucuses, which have less reliable turnout numbers. A small percentage of people vote in primaries but not in general elections, and they are also not included. The remaining 60 million people voted in the primaries: about 30 million each for Republicans and Democrats. But half of the primary voters chose other candidates. Just 14 percent of eligible adults — 9 percent of the whole nation — voted for either Mr. Trump or Mrs. Clinton. The overall shares were about the same in 2008, the last cycle without an incumbent president running. Mr. Trump and Mrs. Clinton will be working to win the votes of these three groups. Polls suggest they will be separated by just a handful of squares.
