Since 1965, the following has significantly changed American political culture:

A. An increase in Asian and Latin American immigration: This has brought about significant demographic shifts and diversity in the American population, leading to changes in electoral politics, policy debates, and cultural influences.

C. An increase in politicization of American non-college youth: The 1960s and subsequent decades witnessed a rise in youth activism and political engagement, particularly in movements related to civil rights, anti-war protests, and grassroots organizing. This has had a lasting impact on American political culture, as these changes have influenced political discourse and policy priorities.

D. An increase in labor organizing and union activism: While the strength of labor unions has varied over time, the 1960s and 1970s saw a surge in labor organizing and activism. This led to the adoption of labor-friendly policies, changes in worker rights, and influenced the broader political landscape.

B. An increase in Americans' average fertility rates: While fertility rates have fluctuated over the years, there has not been a significant increase since 1965. Therefore, it does not qualify as a factor that has significantly changed American political culture.
