The study aimed to examine some socio-economic variables of the human element and their relationship to certain sustainable development factors that contribute to attracting respondents to internal migration in the South Valley region. The research followed both descriptive and quantitative analysis methods to process published and unpublished data, which were obtained through a field survey questionnaire, as well as through data from relevant studies and agencies. The research employed Pearson's correlation coefficient to assess the strength of the relationship between socio-economic variables and the factors attracting internal migration to the study area. A simple random sample method was used, and the data were collected during the winter agricultural season of 2020/2021. The results showed that the highest percentage of residents in the area had been living there for more than ten years, while the lowest percentage was for those who had been living there for less than a year. The correlation analysis between some socio-economic variables in the sample, such as land area and certain factors attracting internal migration to South Valley, revealed a significant correlation between land area and factors such as higher net income per feddan, housing availability, and the presence of relatives. However, no correlation was found with other factors. The study recommended focusing on completing the infrastructure between sustainable population development areas in South Valley to facilitate easy movement between them.
