Recently, Korea is experiencing a rapid increase in single-person households. In particular, like men, the number of single female households is also increasing very rapidly. According to the routine activity theory, single-person households are suitable targets for crime because their ability to defend against crime is reduced. Currently, in Korea, with the increase in single-person (female) households, the number of appropriate crime targets among the three elements of crime continues to increase, and assuming that a motivated criminal always exists, the condition of absence of guardian (single female) If the situation without adequate protection for households is added, crime against single-person (female) households is likely to increase. For this reason, various local governments in Korea are currently implementing crime prevention programs for single-person (female) households. However, proper evaluation of them has not been carried out. In contrast, in other Anglo-American countries, evaluations of various situational crime prevention programs for home invasion crimes have been conducted, and various policies are being implemented based on this scientific evidence. This study raises the need to introduce an effective single-person household crime prevention policy through scientific evaluation of various crime prevention programs in Korea.
