Recent data from the Pew Research Center indicates a notable shift in political affiliation among U.S. adults aged 18 to 29 between 2021 and 2025. In 2021, 63% of this age group identified as Democrats, while 31% identified as Republicans. By 2025, Democratic affiliation in this demographic decreased to 49%, and Republican affiliation increased to 43%. Gender-specific polling further highlights this trend: among young men, 52% identified as Republicans compared to 34% as Democrats, whereas among young women, 58% identified as Democrats and 37% as Republicans. These changes reflect evolving political dynamics within younger Americans over the past several years.
