This study aims to analyze the population changes, as well as the age and gender composition, in addition to population density in the Abu Salim area and all its localities. The study is based on population census data from the years 1973, 1984, 1995, and 2006, along with population estimates for the year 2020. It also seeks to identify the factors influencing population growth during the period from 2013 to 2023. The study employs descriptive and demographic statistical methods, in addition to using appropriate statistical equations and models to measure population growth rates and estimate future trends. The findings reveal several key results, most notably a population growth rate of 1.9% during the period between the 2006 census and the 2025 population estimates. The population increase was particularly concentrated in the southern Abu Salim and Al-Zahf Al-Akhdar localities. Moreover, the population density in the city reached approximately 279 persons per square kilometer in 2006, continuing to rise by 83 persons per square kilometer by the year 2020.............
