(56.25% higher at the 5th percentile, 42.85% higher at the 10th percentile, and 28.57% higher at the 25th percentile), are no different between the 50th and 90th percentile, and are substantially higher (140%) at the 95th percentile. Therefore, among the working class, those who have served in the military have tended to come from poorer circumstances, while there is low representation of the children of the very rich. Indeed, additional analysis (not shown here) finds that the highest income quartile was significantly less likely to have served than the lowest, while the second and third quartiles were not significantly different from the lowest quartile in their likelihood to serve.
In sum, the economic elite are very unlikely to serve in the military.
