As the number of single-female households increases, their safety is emerging as an important issue. The number of single-female households is increasing due to changes in social values, such as strengthening the value of individual freedom and the pursuit of self-actualization, and changing perceptions of marriage. However, this increasing trend is accompanied by problems such as social isolation and risk of crime, and their safety is also threatened. Concerns about this are growing. Single-female households are easily targets of crime, and are especially exposed to physical safety threats such as home invasions, theft, and sexual violence. Today, digital crime is also threatening their safety. Continuous research is essential to identify the various risks that the increasing number of single-female households may face and to promote social and policy improvements. Therefore, this study seeks to examine the need for effective policies for the safety of single-female households by identifying the characteristics of single-female households and examining and analyzing the interaction between personal, social, and policy factors that affect their safety. . I want to see that. In existing studies on the relationship between crime vulnerability and safety awareness of single-female households, personal factors such as age, economic stability, residential environment, social networks, and media exposure have been found to be factors that influence the safety perception of single-female households. Personal furniture. Social-environmental factors and various policy factors were presented. The important point is that the interaction effect between elements has a greater influence than the influence of each of these elements, and a safety policy that takes this into account must be prepared. Safety policies for single-female households that are implemented uniformly without comprehensive analysis are bound to have limitations. In most cases, facilities for crime prevention are provided in residential areas without considering individual or regional characteristics. Therefore, recognizing that the meaning of safety and security needs may be different even for the same single-female household, we must examine the interaction of personal, social environment, and policy factors that influence when establishing safety policies for single-female households. The safety of single-female households was also considered. We must consider the impact on operations and propose a customized safety policy accordingly.
