Background of the Study
Per capita income, representing the average income earned by individuals, is a key measure of economic well-being and an important determinant of overall GDP. In Nigeria, fluctuations in per capita income over the period 2023 to 2025 have provided insights into the country’s economic performance and development progress. Economic theories suggest that increases in per capita income can lead to higher levels of consumption, savings, and investment, which in turn contribute to GDP growth. In Nigeria, where the economy is characterized by a large population and significant income disparities, analyzing the relationship between per capita income and GDP is critical for understanding growth dynamics (Uche, 2024). Rising per capita income can improve living standards, drive domestic demand, and stimulate economic diversification. However, the strength of this relationship is often mediated by factors such as income distribution, labor market dynamics, and structural economic constraints. This study aims to examine the relationship between per capita income and GDP in Nigeria, investigating how changes in average income levels impact overall economic output and exploring the feedback effects between individual well-being and national growth.
Statement of the Problem
Although per capita income is widely used as an indicator of economic progress, its relationship with GDP in Nigeria is not straightforward (Uche, 2024). While improvements in per capita income are expected to contribute to GDP growth, persistent structural challenges such as unequal income distribution, underemployment, and inefficient resource allocation have weakened this linkage. In some cases, increases in per capita income have not translated into proportional growth in GDP due to factors such as high consumption leakage and limited domestic production capacity. These discrepancies create challenges for economic planning and policy formulation, as policymakers struggle to harness individual income gains for broader national development. The complexity of this relationship underscores the need for a thorough examination of the mechanisms linking per capita income and GDP, as well as for strategies that can better convert individual income improvements into aggregate economic growth.
Objectives of the Study
To analyze the relationship between per capita income and GDP in Nigeria.
To identify the factors that mediate the impact of per capita income on national economic output.
To propose policy measures that enhance the positive effects of income growth on GDP.
Research Questions
How does per capita income affect GDP growth in Nigeria?
What factors mediate the relationship between per capita income and national output?
What policy interventions can strengthen the linkage between individual income gains and GDP?
Research Hypotheses
H1: Increases in per capita income positively influence GDP growth in Nigeria.
H2: Structural inefficiencies weaken the impact of per capita income on national output.
H3: Targeted policy measures enhance the contribution of per capita income to GDP.
Scope and Limitations of the Study
This study focuses on the relationship between per capita income and GDP in Nigeria using data from 2023 to 2025. It incorporates national economic statistics and survey data. Limitations include the challenge of accounting for informal economic activities and potential data measurement issues.
