Past studies reveal that military service “runs in the family”: offspring’s service records often accord with those of their parents. To extend this research, this study uses the complete Liberian Housing and Population Census of 2008 to estimate rates of military participation among Liberians living with relatives in the military. The study finds—both in the overall data and in an exactly matched subset consisting of observations that share the same values on all control variables—that Liberians living with a relative in the military participate in the armed forces at over two times the rate of individuals who do not live with a member of the military. This finding provides new insight into military participation and civil–military relations in Liberia and, perhaps, other developing nations.
