Since centralization has already been sunk in the dusty pages of the history, defining social policies and implementing the same have gone apart from centralized administration but become localized, which is the ideal form. This is because it is more convenient that the best of the servicing is rendered by the party that is nearest to the people in terms of serviceableness, usefulness, accessibility, communication and economy. Since municipalities, which are no doubt classified within public administration units, are the service organizations that are closest to people, their social functionality carry high importance compared to other public administrative units and organizations. The social activities of the state and its administrative units that are needed in order to ensure social prosperity and sustain the same are now added new dimensions together with the fact that globalism and neo-liberalism have become widespread. Area of responsibility of municipalities has been widened during the globalism process and therefore importance of local administrations has been risen in parallel of it. On the other hand, responsibilities of municipalities have diversified and intensified at the same time in both quantitative and qualitative terms just because improper urbanism has a considerable run in our country. If we should briefly explain the mission of a local administration, it is to ensure happiness and prosperity of the people living within its borders by making use of in the most effective way the material resources available and its legislative authorities. One can rapidly come to the conclusion that ensuring the happiness and prosperity of the people requires highly strategic and sustainable implementations and services when it is taken into account that almost half of the population in large cities of Turkey such as Istanbul and Ankara live in outskirts of the towns and a majority of it belongs to lower income group. Therefore, central government should furnish authorities and possibilities to particularly municipalities so that they can be successful in the spectrum of duties which covers a variety of services from education to housing, healthcare services, social support and social services. This paper includes a review of the subject in theory first and then an analysis of data from a case study conducted in the light of the projects and data of the Esenler Municipality, the subject local administration of ours.
