This study analyzes the spatial variations of urban hierarchy of Kermanshah province in the period of 1996-2011. This study aimed to explain the uneven distribution of population and social inequality-to reduce the economic disparities across the province. Analysis indicates that 29 cities of Kermanshah in 2011, with a population of about 851,405 people in the city of Kermanshah Province, 62.8% of the urban population ,approximately 16 times and 8times the second and third cities of the same province (Kangavar) population has the most unevenly distributed population. In fact, the lack of central cities in metropolitan networks in urban areas has created instability. This analytic method utilizing GIS, EXCEL, the rank-size model of a class difference, Entropy Coefficient and Lorenz Curve has been done. Results of the entire hierarchy of methods used in urban imbalance and instability tends to show instabilities. Based on a floor equal to 96.6 percent in 2011, more than 141 thousands of people in equations obtained from the following cities ranked as the cities of Kermanshah show much difference between the three periods and the line of normality. The entropy rate of 75 year /8to / 79 in 85 and in year 2011 ، /69 which indicates heterogeneity in the distribution of population was reached. The city of Kermanshah in terms of spatial distribution of population is the worst compared to other cities , so that, the first city ( Kermanshah ) has 216 times more population compared to the second city ( Kvzran ).
