Wisconsin Study: Voting Correlates With Lower Mortality Risk for Seniors

A new analysis of long-term health data indicates that older Americans who vote experience lower mortality rates than those who abstain from the ballot box. The study, which focused on a specific cohort in Wisconsin, quantified the survival gap between participants in the 2008 presidential election and those who did not cast a vote.

The research team, comprising an economist and a social psychologist, utilized data from the Wisconsin Longitudinal Study. This longitudinal project has tracked a random sample of Wisconsin high school graduates since 1957. By cross-referencing this cohort with voting records from Catalist and the National Death Index, the researchers isolated the health outcomes of adults aged 65 and older.

The primary finding shows a distinct survival advantage for voters. Those who participated in the 2008 election were 45% less likely to die within five years of the vote. This statistical advantage persisted over longer timeframes, with voters showing a 37% lower likelihood of death 10 years after the election and a 29% lower likelihood 15 years later.

The researchers extended their analysis to include the 2004 and 2012 presidential cycles. They observed that the correlation between voting and longevity was stronger for the more recent elections held in 2008 and 2012. The effect was less pronounced for the 2004 cycle, suggesting that the timing of the civic act may influence the magnitude of the health benefit.

To ensure that the results were not driven by the fact that healthy people are more likely to vote, the team controlled for several demographic and health variables. They accounted for gender, marital status, income, and pre-existing health conditions. The study also included other forms of civic engagement, such as volunteering, in its statistical model. Even after adjusting for these factors, the lower mortality risk among voters remained statistically significant.

The data revealed that the health benefits of voting were not limited to those who were already in good physical condition. Individuals who were in poorer health prior to the election actually derived a greater long-term benefit. Those with lower initial health status saw a more pronounced reduction in mortality risk 15 years after voting compared to their healthier peers.

The method used to cast the ballot did not alter the health outcome. The researchers compared adults who voted in person with those who mailed their ballots. Both groups experienced a similar reduction in the risk of death over the 15-year observation period. This indicates that the act of voting itself, rather than the physical effort required to go to a polling place, drives the longevity effect.

Political affiliation and election results also did not influence the health benefits. The study found that voters who supported the losing candidate experienced the same long-term health improvements as those who backed the winner. The researchers noted that while losing an election can be stressful, the physiological or psychological benefits of civic participation appear to be consistent regardless of the political outcome.

The exact mechanism behind this link remains unclear to the research team. They noted that previous studies on volunteering have shown that civic engagement can trigger positive biological responses, such as boosting the brain's reward system and reducing stress. These processes may slow aspects of aging. The authors suggested that voting, like volunteering, may function as a shared, altruistic activity that fosters a sense of self-efficacy and social connection, contributing to better health outcomes.
