After the economic crisis, Korea has been facing new issues of poverty. The recent state of poverty, so-called 'new-poverty', have emerged because of a sudden increase in the 'working poor' and its consequences. This condition is the result of all the following problems put together; labor market flexibility, social exclusion, weakening human resources and family support, and the immaturity of the social security system. But the action taken in response by the government is insufficient. Since the employment state of the working poor without public assistance is becoming increasingly unstable, comprehensive measures are required. In this sense, this research is aimed at: reviewing various definitions of the working poor; examining their conditions; understanding why they are poor; analyzing existing poverty policies and; presenting comprehensive coping measures. This research consists of the following parts. First, we reviewed various definitions of the working poor and estimated the scale and the characteristics of them according to the definitions. Second, we studied the dynamics of the working poor's poverty, employment and needs for public assistance. Third, we inspected the government's policies on working poor, concerning the labor market, tax, income maintenance, and social welfare services. Last, but not least, we suggested promotion of labor market opportunities, introduction of Earned Income Tax Credit, right mixture of social welfare services, and expanded coverage of social insurance.
