This study examined the reasons cited by inactive athletic donors at a major NCAA Division I institution for their decision to lapse. A survey was emailed to all inactive donors with a valid email address on file with the athletic fundraising organization at the institution in question. The survey collected demographic information, followed by levels of agreement with the effect that a number of different service and external factors had on their decision to lapse as donors. Descriptive statistics were run on the data, and then a series of chi-square tests were run to determine the relationships that existed between different demographic criteria (including male/female, distance of residence from the university, alumni status, and years of membership) and the reasons cited for lapse. The most frequently-cited factors for lapse were identified and discussed, and the significant relationships between demographic groups and the factors for donor lapse were analyzed and discussed.
