Offenders are compared on their age, race, gender, and education. Computer criminals are found to be younger, more white, more female, and more educated than their non-criminal counterparts. Subsets of computer criminals are then compared to each other using the same four demographic variables. x I. INTRODUCTION Computer crime is a relatively new and misunderstood phenomenon in the field of criminal justice. As computers have become increasingly prevalent, crimes utilizing those computers has grown accordingly. While it was very rare to be the victim of computer crime as recently as a few decades ago, it is now quite common. This increase in cybercrime and cybercrime victimology also corresponds to an increase in cyber criminals, but little is known about who they are, how they think, or what makes them different from criminals who commit more traditional types of crime. One of the reasons that computer criminals are hard to identify and study is because there is very little agreement as to what the term “computer crime” actually means. Moon,
