Final answer:
The groups least likely to vote are those without a high school degree, young adults aged eighteen to twenty-five, and those with lower socioeconomic status due to lesser education and income levels.
Step-by-step explanation:
The group least likely to vote according to their schooling, or level of education, comprises individuals with lower educational attainment and lower socioeconomic status. In particular, this includes those without a high school degree, who have one of the lowest voter turnout rates.
According to research, individuals with less schooling are less "connected" to society and therefore may not see the immediate impact of their vote, leading to lower political participation rates.
Moreover, younger people, especially those aged eighteen to twenty-five, are less likely to vote. They are often still in college or working part-time, which means government policies may seem less relevant to their daily lives.
This group’s low engagement results in them being neglected by political campaigns, perpetuating a cycle of low voter turnout.
In contrast, those with a higher income and level of education, which contribute to a higher socioeconomic status, are much more likely to vote. They tend to be more settled, are more likely to be married, employed, and connected with their communities. All of these factors significantly increase the likelihood of political participation.
