A very common factor is socio-economic background. People who live and/or were raised in poverty are much more likely to participate in criminal behavior than those from wealthy backgrounds. A related factor is level of education completed. Those who graduate from high school and especially from college ted to have much lower rates of committing crimes. So these are all associated factors.
Criminal behavior can be correlated to several different areas. There are the environmental factors such as socioeconomic status, place of birth, and family influence. There are other genetic implications that there have been studies on. In these examples we can see that at some point regardless of the situation you are born into there is a direct genetic correspondence between a child and their blood relation to their parents. For example, a child that is born to parents that exhibit criminal behaviors is adopted by a rich , well to do family. There are still implications that the child will be at risk for criminal behavior because of the genes that trigger certain emotional responses to a given set of stimiuli. Hope this helps.
