To the best of my knowledge, there are no detailed profiles of Muslim terrorists, although serious efforts have been made. Bongar et al. (2007) states that "explanations intended to reduce the causes of terrorism to dispositional, intrapersonal factors are too simplistic...as are the material conditions in which terrorism takes place". The most common denominator noted among terrorists is that most have high levels of education. Some documents that may assist you further in your research are listed below.

The literature on terrorism indicates that the notion of a terrorist 'profile' is very questionable. So far, the most reliable elements of such a profile appear to be that most terrorists are young and most are male. Such information is of little practical use of course.

There is not one clear 'terrorist' typology; instead terrorists fulfil numerous roles, embrace a wide variety of ideological views and operate in disparate organizational structures. As Victoroff (2005) writes: ‘any effort to uncover the “terrorist mind” will more likely result in uncovering a spectrum of terrorist minds’.

With regard to terrorists of the 1980s, McCauley and Segal (2009) found that most were male, most were young, they were predominantly from middle-class backgrounds and had at least some university education.

In his study on 242 European jihadists, Bakker (2006) concludes that ‘there is no standard jihadi terrorist’. His sample consisted predominately of single males, not participarly young, often from the lower socioeconomic strata and with a criminal record. By contrast, Sageman's (2004) work on internaitonal jihadist terrorists found that they mostly led middle-class existences.

In short, there appears to be far more diversity than uniformity when it comes to terrorist profiles, Islamic or otherwise.
