Abstract
This study provides a rigorous and data-driven examination of migration from Nigeria to the United Kingdom through a multi-dimensional, data-driven framework that integrates economic push factors, immigration policy, occupational outcomes, and remittance flows. Using datasets from the World Bank, United Nations Department of Economic and Social Affairs, UK Census records, and the DEMIG-QuantMig database, the study analyses trends from 2000 to 2024 to understand the structural forces shaping this migration corridor.
The findings robustly demonstrate that deteriorating economic conditions in Nigeria,characterised by rising inflation, unemployment, and widespread underemployment,serve as powerful drivers of emigration. Despite increasingly restrictive UK immigration policies, Nigerian healthcare migration has continued to rise, with regression results indicating a strong negative relationship between policy openness and migration levels. This provides strong empirical evidence that labour demand in the UK, particularly in healthcare, alongside persistent economic pressures in Nigeria, outweighs the restrictive effects of policy.
The study also introduces a Brain Waste Index to assess occupational outcomes, revealing overall improvement in professional integration between 2001 and 2021 but significant geographic disparities across UK regions. Finally, analysis of remittance flows shows only a weak relationship with migration volume, indicating that the economic benefits of migration depend more on macroeconomic conditions than on the size of the diaspora.
Overall, the project demonstrates that the Nigeria,UK migration corridor is shaped by interconnected economic, policy, and labour market dynamics, highlighting the need for a multi-dimensional approach to understanding migration patterns.
