Population, Growth and Economic Inequality in Urban Areas Mamminasata, South Sulawesi, Indonesia

Decentralization, population, development and economic growth are factors to reduce economic imbalances in a region. The purpose of this study is to see the extent of economic inequalities in Urban Area Mamminasata (Makassar, Maros, Sungguminasa/Gowa, and Takalar) as well as the factors that led to it. The data obtained are then analyzed to determine the income disparity by using Williamson Index. The Williamson Index analysis is used to measure how much economic inequality is between regions. The value of the Williamson Index derived from the calculation of per capita local income and the total population of each area. The data used in this study is secondary data, which is the annual data during 2012-2016 and obtained from the agency. A criterion is a moderate, high-level gap. The size of inequality if the value of the Williamson Index closes to 0 means that in the area of imbalance small or more evenly and if the value of the Williamson Index closes to 1 then the area occurs a very large or widened inequality. From the research result of difference, criterion indicates that Sungguminasa/Gowa Regency is at the highest condition of inequality in Urban Area of Mamminasata with a value of the variation of equal to 0903. In the Mammminasata Urban Area, the lowest level of index inequality of Williamson is in the area of Makassar City with an average value of 0.383 than in Maros District with a high imbalance rate of 0.801 next Takalar District with Williamson inequality value of 0.821 and included in the category of high inequality. Given the economic growth both directly and indirectly will affect the problem of regional disparities. The difference in revenue sharing is an imbalance in economic development between different regions in a region that will also cause per capita income disparities between regions.
