The lasting impact of WWI veteran bonuses on children’s longevity

This study looks at how a surprise one-time cash bonus in 1936—given to World War I veterans—affected the long-term health of their children. The bonus was large for its time, equal to the entire per capita income of 1936. Researchers examined whether kids born around the time of the payout, especially those in utero or in their first year, lived longer as a result of the extra household income. They found that children of veterans born in 1936 lived about 7.6 months longer in old age compared to others. While the effect was strongest for those exposed very early in life, impacts for others were smaller and mostly not statistically significant. The study carefully ruled out other explanations by comparing families and running multiple tests. It also found bigger gains for children from lower-income families and noted that veteran households saw major improvements in housing values after the bonus. These better living conditions likely played a role in the health and longevity boost.
