White paper on crime 2011 Part4/Chapter6/Section1/2
Fig. 4-6-1-2 shows the number of previously convicted adults cleared for non-traffic penal code offenses (limited to those with previous convictions for offenses other than Road Traffic Act violations) and the rate of previously convicted adults (refers to the percentage of previously convicted adults to adults cleared for non-traffic penal code offenses) over the last 20 years. The number of previously convicted adults cleared for non-traffic penal code offenses continued to increase from 1996, but then decreased slightly over four consecutive years from 2007, and was 66,766 in 2010 (down 4.0% from the previous year). However, the rate of previously convicted adults remained within the range of 22 to 30% from 1991. Examining previously convicted adults cleared for non-traffic penal code offenses in 2010 by number of previous convictions revealed that those with one previous conviction accounted for the highest proportion at 39.1%, but with the proportion of those with five or more previous convictions also being high at 21.9%. In addition, those with previous convictions for the same type of offense (according to the statistical classification made by National Police Agency) accounted for 51.6% (Source: Criminal Statistics by National Police Agency).
Fig. 4-6-1-3 shows the percent distribution of adults cleared for non-traffic penal code offenses by history of previous convictions and type of offense in 2010.
The rate of previously convicted persons among adults cleared was 28.2% for total non-traffic penal code offenses, but was remarkably high for robbery (46.0%) and fraud (39.8%).
The percentage of persons with previous convictions for the same type of offense (according to statistical classifications made by the National Police Agency) was 14.5% for total non-traffic penal code offenses, but was high for theft at 19.3%. The percentage of persons with five or more previous convictions for the same type of offense was 1.6% for total non-traffic penal code offenses, but was high for both theft and fraud at 2.4% and 2.8%, respectively.
The percentage of persons who had previously been cleared for Stimulants Control Act violations (including Act on Special Provisions for Narcotics violations concerning stimulants) and were cleared again for violations of the said Act (repeat offenders for the same type of offense) was high at 60.2% when compared with the rate of repeat offenders among persons cleared for non-traffic penal code offenses. In addition, the prosecution rate for violations of the said Act is extremely high (83.5% in 2010). This then leads to the assumption that the percentage of those with previous convictions for the same type of offense is remarkably high for violations of the said Act when compared to that for non-traffic penal code offenses.
