What is the age breakdown of independent voters?

Party identification data reveals that while 3/4 of the Silent Generation affiliate with a political party, the majority of voters born after 1980, Millennials and Gen Z, do not.

A majority of voters born after 1980 identify as independent

The traditional political battle between Republicans and Democrats has become a relic of the past. American political division is no longer defined strictly by party but increasingly by age. Data suggests that younger voters—Millennials and Gen Z—are fundamentally changing American politics by rejecting party affiliation in favor of political independence, issue-based voting, and split-ticket choices.

This means that hyper-partisan messaging that once resonated with a party's “base” is losing relevance. The Republican and Democratic “bases” are disproportionately older, and their voters are already locked in. Meanwhile, younger voters are more willing to listen to arguments from both sides—and their growing numbers make them an electoral force that can’t be ignored.  

Engaging with independent voters is now a requirement for electoral victory. There is no chance to win an election without swinging the independent vote.  

This was true in 2016 when Trump won independents by 4%, and again in 2020 when Biden won them by 13%. The 2024 election followed the same pattern: Trump carried all nine key swing states en route to victory, and he won independents in seven or eight of those states, depending on the exit poll.

Younger voters aren’t "waiting to join a party"—they’re staying independent

Historically, younger voters started out as independents and eventually joined a political party as they got older. That pattern is breaking.

A Gallup trend analysis from Axios illustrates this shift. Younger voters are not just delaying party affiliation—they're rejecting it altogether.

If you’re 45 or younger, this data likely makes perfect sense. If you’re older, you might be skeptical or assume it’s an anomaly. But the numbers don’t lie—party loyalty is declining, and the old red vs. blue narrative is losing relevance.

  • Younger voters rank economic issues, climate change, and civil rights as higher priorities than immigration (The Economist/YouGov)
