It is essential that urban governments accommodate the vulnerable with basic minimum income, housing and socially integrating environment for their daily living. In Korea, the government has played the major role in poverty reduction by providing the National Basic Livelihood Security(the public assistance program) and the Permanently-Rented Housing schemes. However, there has been unique contradiction that entailed by those anti-poverty measures. That is, so-called the formation of poor neighborhood concentration and the unequal distribution of financial resources for the local public assistance provision. The study examines critical theories, explaining urban poverty(from the perspectives of urban ecology and human geography), the inverse care law, and the quality of life in community living. Also, it is analyzed that two districts, with highly-concentrated low income households(Kang-seo and Nowon), spent two times more resources for poor relief than the other two(Song-pa and Seo-cho) which have the lowest proportion of the poor among the Seoul districts. In addition, findings show that the districts with concentrated poor neighborhoods are ill at ease by the heavy burden of supporting the poor, not being able to afford enough resources for their own initiatives. Thus, there is urgent needs for the central government to enact measures for improving the regional disparity, in terms of the poor relief expenditure.
