The association of more crime with youthful age is widely accepted in social science. However, a literature search revealed no studies of the age-crime relationship that controlled for young ages’ economic disadvantage. This research gap is addressed using the California Criminal Justice Statistics Center’s arrest detail and Census poverty statistics for 2010. When poverty rates were controlled, younger and older ages’ violence disparities largely disappeared. Where teenagers and emerging adults display typical middle-aged demographics (two thirds non-Latino, White, or Asian, poverty levels under 10%), they display "middle-aged" violent crime rates; where ages 40 to 69 have typical teenage demographics (54% Black or Latino, 17% in poverty), they display "teenaged" violent crime levels. These findings challenge conventional theories associating violence with young age.
