The socio-economic inequality index of development affects the plans of policy makers, investment decisions and services throughout the country such as retailing and banking sectors. Thus, to know the gap between regions or cities becomes a more crucial fact for governments.

For this purpose, different institutions such as TUIK (Turkish Statistical Institute), DPT (State Planning Organization) and banks conduct and publish annual socio-economic development indexes for cities in Turkey. This study aims to provide a projection related to socio-economical situation of Turkey and development level of each city in terms of socio-economic development in future. In this context, various classification methods as Artificial Neural Network-ANN, Bayes Network and Support Vector Machine-SVM algorithm are used on WEKA which is a collection of machine learning algorithms for data mining tools. Besides, K-Means method, a clustering technique, is utilized to provide insight about progressed areas in Turkey.
