Geopolitical Analysis of the Demographic Changes Necessary and Spatial Planning Policy Making in the Field of Geographical Distribution in Iran

Iran needs population growth in order to achieve high weight in the region and world as well as to obviate peripheral threats. Iran''s area is so vast that it can accommodate more population than the current population. The country having population density of 46 individuals per square kilometer ranks 162 in the world. However، quality and efficacy are necessary for a population to lead high weight. Therefore، it has been attempted in this research to explain necessity of population growth of the country geographically; and to study optimization of indices for these changes and policy making in order to lead the changes in the framework of the land preparation plans. The research questions are: Which indices are considered as priority from the view point of the land preparation، concerning the population growth; and which areas and provinces are more apt to accommodate more population? General purpose of this study is to consider crucial land preparation indices in population growth policy and to prioritize provinces based on the indices. The research method is descriptive-analytical.
