Migration plays a pivotal role in shaping regional economies and social structures. In recent years, Uttar Pradesh (UP), traditionally known for high out –migration, has witnessed an increase in in-migration due to factors such as urban expansion, industrialization, and government-led economic initiatives. This study aims to examine the economic and social outcomes of growing in-migration in UP by analyzing key variables, including Gross domestic product (GDP), per capita income, total population, urban population, and total in- migration. Using data from the Census of India, Economic Surveys, and National Sample Surveys, this research applies statistical methods to assess the impact of migration on economic growth and urbanization. The study explores whether in-migration fosters economic development or creates socio-economic challenges like urban congestion and employment competition. The findings of this study are expected to provide valuable insights into the role of migration in regional economic transformation. By understanding the interplay between migration, economic indicators, and develop strategies to harness the benefits of in-migration while mitigating potential negative consequences.
