Migration patterns in Pakistan have been heavily influenced by geography, political conflicts, and development projects. Domestic migration includes the development of Punjab canal colonies in the early 1900s which increased rural and urban populations, and rural-urban migration today driven by industrialization. International migration was impacted by the 1947 India-Pakistan partition which increased populations in Punjab and Sindh, as well as conflicts with India, Afghanistan, and Bangladesh which produced refugees. Emigration is now significant, with over 95% of emigrants being male workers going to the Middle East, UK, and USA. Remittances are a major economic impact, transforming infrastructure and appliances in recipients' homes while also creating socioeconomic challenges.
