Intro-Biological
Biological theory’s say that the genetic makeup of a person DNA makes them a criminal rather than rational thinking and logic. This is also referred to nature vs. nurture tis mean that criminal behaviour is more natural and that we are born with it rather than it been learnt.
Causal factors
Negative family influences
This includes being neglected by your family, a lack of parental involvement-children who don’t have a close relationship with parents are at risk for committing crimes young and are more likely to drink alcohol or smoke cigarettes. Another one is bad habits made by a family member; a child of a criminal parent is more likely to become a criminal themselves.
Lack of education
A Factor which comes most readily to mind is the extremes of poverty and poor education. Juveniles from poor communities are not even interested in becoming educated because there are not any decent paying jobs for them anyway. By not going to school, these juveniles are not are not developing the proper mental framework with which they can make good choices in life. The growing numbers of poor communities does not help the situation. It is old news that crime follows poverty. Americans should be concerned that juvenile crime is being fuelled by a lack of education and poverty.
Poverty
A child who fails to get pocket money may steal from his father's purse. A father may steal to supply his children food, clothing, and other necessities of life. Often, poverty operates indirectly too. A child from a poor family may run away from his home to escape worry, irritability, desperation and discord of parents and may come to associate with delinquent gangs.
Unemployment
People will not work due to their lack of education and the limited jobs that are out there and other easy ways of making money without working; this includes theft, drug and arms selling,
