Difficulty: HardVoter Turnout and Demographic Influence

Consider the following data representing voter turnout rates by age group during a recent presidential election in two states with different voting laws:

Age GroupState X (Strict Photo ID Required; No-Excuse Mail-In Voting Not Allowed)State Y (Automatic Voter Registration; All-Mail Voting Conducted)
18–2438%38\%56%56\%
25–4448%48\%62%62\%
45–6465%65\%72%72\%
65 and older74%74\%78%78\%

Which of the following statements is best supported by the data in the table?

  1. A
    The lower voter turnout among young voters in State X indicates that strict voter identification laws violate the Twenty-Sixth Amendment by raising the practical voting age.
  2. B
    The higher turnout rate among older populations in both states is primarily a generational effect, meaning these specific individuals have always voted at high rates throughout their lives regardless of institutional barriers.
  3. Strict voter registration and identification laws disproportionately reduce turnout among younger cohorts because they increase the relative transaction costs of voting for groups with less residential stability and bureaucratic experience.Answer
  4. D
    Younger voters in State X vote at lower rates because they utilize prospective voting models to evaluate candidate platforms, whereas older voters rely on retrospective models that simplify participation.

Answer

Strict voter registration and identification laws disproportionately reduce turnout among younger cohorts because they increase the relative transaction costs of voting for groups with less residential stability and bureaucratic experience.
The data shows that voter turnout is higher in State Y (facilitative voting laws) than State X (restrictive voting laws) for all groups, but the difference is most pronounced among younger voters (18–24 and 25–44). Younger voters generally face higher transaction costs to voting—such as changing registration after moving or acquiring specific photo identification—due to lower residential stability and less experience navigating government systems. Reducing these barriers through policies like automatic voter registration and all-mail voting disproportionately increases turnout among younger demographic groups.

Step-by-Step Solution

1
Analyze the table to compare voter turnout rates between State X and State Y across all age groups.
State Y (which has lower institutional barriers like automatic voter registration and all-mail voting) has higher turnout across all groups. However, the difference is largest for the 18–24 group (18 percentage points difference) compared to the 65 and older group (4 percentage points difference).
This establishes that institutional voting rules have a differential impact depending on the demographic age cohort.
2
Relate these findings to political science concepts of transaction costs and demographics.
Younger voters are more mobile, less likely to have government IDs with current addresses, and have less experience with administrative processes. Reducing institutional barriers (State Y) disproportionately helps them overcome these transaction costs.
This explains the demographic mechanism behind the data trend.
3
Evaluate the options against this political science reasoning.
The statement regarding transaction costs and demographic characteristics accurately explains the data trend and the interaction of variables, whereas the other options rely on political science misconceptions.
