Younger Citizens

younger citizen

According to the age-cohort tendency, significant changes in the pattern of political socialization are typically concentrated among younger citizens.

To arrive at this answer, you can use the following information:

1. Age-cohort tendency: The age-cohort tendency refers to the idea that individuals' political beliefs and attitudes are influenced by the historical events and experiences they encountered during their formative years.

2. Significant changes in the pattern of political socialization: Political socialization refers to the process through which individuals acquire their political beliefs and values. Significant changes in political socialization occur when there is a shift in the dominant factors influencing political beliefs and values within a given population.

Considering these points, we can deduce that younger citizens are more likely to experience significant changes in their pattern of political socialization. This is because they are exposed to different historical events and experiences compared to older generations. As they mature, these experiences may result in different political beliefs and values compared to previous generations.
