A survey by Gallup on the relationship between well-being and community service shows a direct positive correlation. The overall pattern cut across income and age group. The Gallup analysis also found a connection between community service and key indicators of emotional health, such as stress and worry.
Sadly it seems that many more U.S. adults do not receive recognition for community service, so this study suggests that communities would be wise to do more to promote opportunities for residents to volunteer and engage in community service and businesses can help by allowing their workers time to engage in volunteer activities.
