Modeling Population Age composition in Southern Upper Egypt Region (1976-2017)

Age composition has particular importance in population studies because it affects and affected by all demographic variables. In this research discusses model of population age composition in the South Upper Egypt region, which includes the governorates Suhag, Qena, Luxor and Aswan. This research also aimed to create a composite index of the nature of population growth in South Upper Egypt region within period 1976 - 2017. The goal is a determining the pattern and trends, which shaped population age composition in this region, relying on quantitative and spatial dimensions, by using a time-space approach simultaneously. Through the process of creating a model, that expresses the nature of the evolutionary direction with an explanation of these stages. These stages summarized a set of significant change patterns and trends, which combined into three basic groups:
1) A group of units with strong positive change, appearing in a four-color group at the top of the model.
 2) A group of units with strong negative change, and appearing in a four-color group at the bottom of the model.
 3) A group of units with slight changes, whether positive or negative, and a quadruple color group appears in the center of the model.
