Background of the Study
Labor market informality—characterized by unregistered, unregulated, and often precarious forms of employment—is a pervasive feature of Nigeria’s economy. Informal employment provides livelihoods for a large segment of the population, yet it is typically associated with lower wages, limited social protection, and poor working conditions. In Nigeria, where the informal sector accounts for a significant share of economic activity, the effects of informality on economic inequality are of critical concern (Adeniyi, 2023). Recent studies conducted between 2023 and 2025 indicate that labor market informality exacerbates income disparities, hinders social mobility, and undermines the overall efficiency of the economy. Informal workers often lack access to social security, formal training, and legal protections, which perpetuates a cycle of poverty and inequality. While informality can offer flexibility and income generation for those excluded from formal employment, it also contributes to economic segmentation and unequal distribution of resources (Okoro, 2024).
The relationship between labor market informality and economic inequality in Nigeria is complex. On one hand, the informal sector provides vital employment opportunities, especially in regions where formal job creation is limited. On the other hand, the prevalence of informality limits workers’ bargaining power, reduces their lifetime earnings, and restricts access to upward mobility. This duality presents significant challenges for policymakers seeking to reduce inequality while fostering inclusive economic growth. The present study aims to assess the impact of labor market informality on economic inequality in Nigeria by analyzing income distribution data, examining the structural determinants of informality, and evaluating the social consequences of prolonged informal employment. The research will combine econometric analyses with qualitative insights from affected workers and policymakers to provide a comprehensive understanding of how informality shapes economic inequality in Nigeria (Adeniyi, 2023).
Statement of the Problem
Labor market informality in Nigeria has long been identified as a key driver of economic inequality, yet its precise impact remains underexplored. The primary problem is that informal employment, while providing immediate income opportunities, often results in lower wages, job insecurity, and limited social mobility. This, in turn, perpetuates income inequality and contributes to broader socio-economic disparities (Okoro, 2024). Additionally, the lack of effective regulatory frameworks and social protection mechanisms for informal workers exacerbates these inequalities. The fragmentation of the labor market, with a large proportion of workers outside the formal sector, undermines efforts to implement inclusive economic policies and hampers sustainable development. This study seeks to address these issues by investigating the extent to which labor market informality contributes to economic inequality, identifying the channels through which this occurs, and proposing policy measures to reduce inequality by promoting formalization and enhanced worker protections.
Objectives of the Study
-
To assess the relationship between labor market informality and economic inequality in Nigeria.
-
To identify the mechanisms through which informal employment contributes to income disparities.
-
To propose policy interventions aimed at reducing economic inequality by addressing labor market informality.
Research Questions
-
How does labor market informality affect income distribution and economic inequality in Nigeria?
-
What mechanisms mediate the relationship between informal employment and income disparities?
-
What policy measures can promote formalization and reduce economic inequality?
Research Hypotheses
-
H₁: Higher levels of labor market informality are significantly associated with increased economic inequality.
-
H₂: Informality contributes to income disparities through reduced wages and limited access to social protections.
-
H₃: Policies that promote formalization and worker protections can mitigate the adverse effects of informality on economic inequality.
Scope and Limitations of the Study
This study focuses on the impact of labor market informality on economic inequality in Nigeria from 2010 to 2025, using national income surveys, labor statistics, and qualitative interviews. Limitations include data collection challenges in the informal sector and difficulties in isolating the effects of informality from other economic variables.
