answer:I have searched some scholarly journals and have found little information on the socioeconomic status of military enlistees. I’ll share some of the good information, but since I had to log into the library website to get to them, links wouldn’t work here so I can’t include the whole article. From an article in the journal Foreign Policy, from September 4, 2004: “The Pentagon does not keep information on the socioeconomic status of recruits, but evidence suggests that the lower middle class (regardless of race) bears a disproportionate burden. The military’s refusal to accept those without a high school diploma and a clean criminal record often prevents the most disadvantaged from enlisting. As the survey notes, “[T]he biggest predictor of whether you’re in the military today is the unemployment rate in your home county.” I also found many articles analyzing the contents of the Heritage Foundation study posted in the other thread that mostly agree with the data. I think the most pertinent information here is that the Pentagon doesn’t track socioeconomic information on military recruits.
