There has been much disagreement over the relative safety and merits of solo diving. Up to 2003, very few statistics existed regarding the impact of solo diving on safety, as the subject had not been specifically studied. A 2006 report from the British Sub-Aqua Club (BSAC) concluded that "BSAC currently takes the view that based on evidence from available statistics and risk assessment, the increased risk attendant to allowing planned solo diving is unacceptable". The data underlying the statistics which are used to point to the dangers of solo diving are questionable: for example, divers who end up dying alone but originally had started out as part of a buddy pair are often considered to be "diving solo" in such statistics, but whether the separation was a consequence of the triggering incident rather than a cause is not analyzed.
