Statistical Analysis of Navy Personal Motor Vehicle Fatalities
January 1, 2009

The DASN (Safety) asked CNA to identify individual risk factors that contribute to motor vehicle fatalities across the Navy. We conducted a statistical analysis, characterizing the relationship of various demographic factors and career events to these outcomes. We looked separately at motorcycle accidents, an area of interest because of the growing numbers of motorcycle deaths among military personnel. The objective of the study is to determine, in an analytically sound manner, the factors that explain vehicle fatality rates. The hope is that this will aid in selecting tools and interventions to reduce deaths.

The Effect of Deployment Tempo on Marine Corps Selected Reserve Retention
July 1, 2007
Since September 11th, 2001, the Marine Corps has involuntarily activated considerable numbers of the Selected Marine Corps Reserve (SMCR) to support Operation Noble Eagle (ONE), Operation Enduring Freedom (OEF), and Operation Iraqi Freedom (OIF). This presidential mobilization of the Reserves represents the longest period of involutary activations since the formation of the All-Volunteer Force. In this paper, we examine how this increase in operational tempo has affected the composition of and retention in the SMCR. We take two approaches in our analysis. First, we use descriptive statistics to understand changes in the SMCR between September 2001 and September 2006. Second, we use survival analysis to determine the effect of activation on a reservist’s decision to stay affiliated with the SMCR.
