Background of the Study :
The informal sector constitutes a significant portion of Nigeria’s economy, employing a large share of the workforce. Informal employment encompasses activities that are not regulated by formal labor laws and often lack social security benefits. In Nigeria, the informal sector plays a critical role in income generation, particularly in rural areas and urban peripheries where formal job opportunities are scarce (Balogun, 2023). It serves as a buffer during economic downturns and provides a livelihood for millions. However, while the informal sector contributes to economic growth by generating employment and fostering entrepreneurship, it also presents challenges such as low productivity, limited access to finance, and inadequate social protection.
Recent studies from 2023 to 2025 indicate that informal employment can both stimulate and constrain economic growth. On one hand, the sector’s flexibility and ability to absorb labor contribute to reduced unemployment rates and support consumer demand. On the other hand, the lack of formal training, investment in technology, and regulatory oversight often results in low wages and poor working conditions. This dual nature of informal employment creates a complex dynamic that policymakers must navigate. The study investigates how informal sector employment influences Nigeria’s overall economic growth by examining its contribution to GDP, its role in poverty alleviation, and its impact on formal sector development. By integrating quantitative data on employment and economic performance with qualitative interviews from informal workers and policymakers, the research seeks to provide a balanced evaluation of the informal sector’s role in driving or hindering economic growth (Ibrahim, 2024).
Statement of the Problem :
Although the informal sector is a major contributor to Nigeria’s economy, its impact on sustainable economic growth remains ambiguous. A significant problem is the sector’s inherent vulnerability, as informal workers often lack access to formal financial services, social security, and legal protection (Oluwaseun, 2024). This situation not only undermines individual livelihoods but also limits the potential for productivity improvements and formal sector integration. The informal sector’s predominance may also lead to an underestimation of the true scale of economic activity and hinder effective policy formulation aimed at boosting long-term growth.
Furthermore, the absence of formal regulatory frameworks and standardized practices in the informal sector results in low productivity and limited technological innovation. While the sector provides a critical safety net, its contribution to tax revenue and overall economic development is diminished by the prevalence of unregistered and unregulated activities. This disconnect between the sector’s potential and its actual performance calls for an in-depth investigation to identify the structural weaknesses that prevent the informal sector from fully contributing to Nigeria’s economic growth. The study aims to analyze these challenges and explore strategies that could formalize and improve the productivity of informal employment, thereby promoting a more robust and inclusive growth model (Chukwu, 2025).
Objectives of the Study:
To assess the contribution of the informal sector to Nigeria’s economic growth.
To identify the challenges hindering productivity and formalization in the informal sector.
To recommend strategies for integrating informal employment into sustainable economic development.
Research Questions:
How does informal sector employment affect Nigeria’s economic growth?
What are the key challenges limiting the productivity of the informal sector?
Which policy interventions can facilitate the formalization and growth of informal employment?
Research Hypotheses:
The informal sector significantly contributes to Nigeria’s GDP but limits sustainable growth.
Lack of formalization and regulatory support hampers productivity in the informal sector.
Targeted policy reforms can improve the productivity and integration of informal employment.
Scope and Limitations of the Study:
This study focuses on informal employment in Nigeria from 2015 to 2024, primarily analyzing its economic contributions and challenges. Limitations include reliance on unstructured data and measurement difficulties inherent in the informal sector.
Definitions of Terms:
Informal Sector: Economic activities that are not regulated by formal labor laws or subject to taxation.
Economic Growth: The increase in a country’s output of goods and services.
