Abstract
The study of the age structure is an important element to follow the changes between different population groups, and based on that, the aim of the study was to study the age structure and its indicators for the population of a modern district with its administrative borders(1997-2020).
The study showed that the age structure is constantly changing, as the general trend of the younger age groups is decreasing, which led to a decrease in the proportion of the youngest group (0-14) years. While the middle age groups (15-64 years) their percentages tended to increase. As for the elderly category, it was the least variable in the amount of the ratio and the most volatile and unstable in the direction of change. The relative change in the age structure contributed to the change in the dependency ratio, median age and aging index. The dependency ratio tended to decrease in all its types. As for the median age, as a result of the increase in life expectancy at birth and the increase in the number of the population in the middle age groups, this contributed to raising the median age.
