how different types of organisation led to different value systems and choices
all criminal behaviour is learned through interaction
if an individual was exposed to criminality and delinquency more than conformity, more likely to be criminal
' a person becomes delinquent because of excess of definitions favourable to violations of law over definitions unfavourable to violation of law'
differential associations vary in length, intensity, frequency and duration
crime and delinquency rates tended consistently to be lower in areas of high socio-economic status and higher in areas of relative socio-economic deprivation
