Final answer:
The number of independents in the United States is not falling, but rather increasing, especially among young Americans who are disenchanted with partisan politics.
Step-by-step explanation:
The question about whether the number of independents in the United States is falling is false. Evidence from polls and studies, including data from Gallup, shows that there is a rise in the number of self-identified independents over recent years. This increase occurs as the Republican Party has seen a decline in party membership, indicating a shift in political identification among the U.S. electorate. Young Americans, in particular, are less likely to identify with traditional political parties due to increasing partisanship, leading to a higher number of young people identifying as independents, despite many leaning towards a particular party come election time.
