Others, like Roderick Hindery, have sought to discern profiles in the propaganda tactics used by terrorists. Some security organizations designate these groups as violent non-state actors. A 2007 study by economist Alan B. Krueger found that terrorists were less likely to come from an impoverished background (28 percent versus 33 percent) and more likely to have at least a high-school education (47 percent versus 38 percent). Another analysis found only 16 percent of terrorists came from impoverished families, versus 30 percent of male Palestinians, and over 60 percent had gone beyond high school, versus 15 percent of the populace.A study into the poverty-stricken conditions and whether terrorists are more likely to come from here,show that people who grew up in these situations tend to show aggression and frustration towards others. This theory is largely debated for the simple fact that just because one is frustrated,does not make them a potential terrorist.To avoid detection, a terrorist will look, dress, and behave normally until executing the assigned mission. Some claim that attempts to profile terrorists based on personality, physical, or sociological traits are not useful. The physical and behavioral description of the terrorist could describe almost any normal person. the majority of terrorist attacks are carried out by military age men, aged 16 to 40. Non-state groups
Groups not part of the state apparatus of in opposition to the state are most commonly referred to as a "terrorist" in the media.
These divergences have made it impossible for the United Nations to conclude a Comprehensive Convention on International Terrorism that incorporates a single, all-encompassing, legally binding, criminal law definition of terrorism. The international community has adopted a series of sectoral conventions that define and criminalize various types of terrorist activities. Since 1994, the United Nations General Assembly has repeatedly condemned terrorist acts using the following political description of terrorism:

Criminal acts intended or calculated to provoke a state of terror in the public, a group of persons or particular persons for political purposes are in any circumstance unjustifiable, whatever the considerations of a political, philosophical, ideological, racial, ethnic, religious or any other nature that may be invoked to justify them. U.S. law
Various legal systems and government agencies use different definitions of terrorism in their national legislation. U.S. Code Title 22 Chapter 38, Section 2656f(d) defines terrorism as:
"Premeditated, politically motivated violence perpetrated against noncombatant targets by subnational groups or clandestine agents".18 U.S.C.
