For this report, the researchers analyzed data from 2 years of the U. S. Army Recruiting Command USAREC New Recruit Survey NRS to see whether substantial seasonal variations in characteristics of accessions exist. Variables were selected for investigation based on preliminary Chi square analyses conducted on 1 year of NRS data. Results indicate that Armed Forces Qualifying Test AFQT category, age at contract, sex, geographic region, enlistment term, length of Delayed Entry Program DEP, first contact with an Army recruiter, and circumstances of first contact appear to have substantial seasonal effects. Enlistment incentives show some statistically significant differences across the year, but seasonal effects may not be of practical significance. Ethnicity, educational goals, plans to use the G.I. Bill, and hometown size do not seem to have seasonal patterns among new recruits. In general, for variables that are affected, the major contrast is between summer and winter accessions.
