NOTE: Lower 95% and Upper 95% bounds provide the 95% Confidence Interval for % Arrested at Least Once. The probability of arrest per offense is given by the number of arrests in the year preceding the baseline interview divided by the number of self-reported offenses in the year preceding the baseline interview. The average of this quantity for each group is presented as the Mean Probability of Arrest per Offense.
