certain criteria are used to define the informal sector, such as size, ease of entry, legal status, ownership,
management and technology; the International Labour Organization (2003) identifies the informal sector by
employment categories. ILO perhaps thought informal employment was both self-employment and wages that
were often not recognized, regulated, or protected by legal or regulatory frameworks; such employment
categories include; Self-employment which are self-employed workers, family business heads, and unpaid
family workers; and wage workers which includes informal workers, casual workers without permanent
employer, domestic workers, paid domestic workers, temporary and part-time workers, and unregistered
workers; whereas, employers according to OECD (2009) includes owners and owners of informal enterprises.
Informal employment mainly refers to employment in companies that have no registration and no social security
protection for their employees.
Howbeit, the contributions of the informal sector in terms of job creation, capital saving and mobilization,
efficiency, strong links with other sectors, use of local technology training for entrepreneurs and self cannot be
overemphasized. Nnabuife et al (2020) is of the view that since the early 1980s, Nigeria's economic situation
has deteriorated seriously such that income per capita has significantly plummeted while wage employment has
diminished. The informal economy as posited by the Bank of Industry-BOI- (2018) has contributed to economic
growth and Gross Domestic Product (GDP) accounting for more than half of global employment and up to 90%
of employment in some of the poorest developing countries and accounts for 65% of Nigeria's GDP. Despite
relatively high participation rates, women in Nigeria continue to face several interlinked challenges within the
labour market. Nwokoye (2025), points out that a major concentration of female workers in the informal sector,
where jobs are often unstable, poorly paid, and lack legal protections such as sick leave or maternity benefits.
Situations of this nature expose women to particularly vulnerable and precarious conditions especially during
economic shocks like COVID-19 pandemic where informal jobs were among the hardest hit. In addition, to
economic vulnerabilities, cultural norms places a disproportionate share of unpaid care responsibilities on
women.
Nigeria according to Onyebueke and Geyer (2011) has the largest informal sector in Africa, a predominance that
stems from its massive population which according to World Population Review (2025) stands at 237’ 528’ 000
with 0.56 in Human Development Index (HDI) as at present and this falls short of current global average of
0.744, which places Nigeria low in human development. In addition, to decades of poor economic performance
denoted by a high unemployment rate which according to National Bureau of Statistics (NBS) is 4.3% as of Q2,
2024 as well as multidimensional poverty incidence of 63% or 139million people living in poverty according to
the World Bank (2025) poverty rate projection for Nigeria. World Bank (2025) studies reports that Nigeria's
informal sector is significantly accounting for over 40% of GDP and an estimated 37.5million people were
employed in the sector as of 2019. While employing over 92.7% of the workforce as of Q1, 2024, (NBS, 2024).
Similarly, Dell’Anno and Omobola (2020) reports that the size of informal economy is well above 67% with
80.4% according to the World Bank Report (2021) of Nigeria’s employment being in the informal sector. World
Bank Report (2022), show that 82.1% of women actively participate in the informal sector such as agriculture
and small businesses, in comparison to men. Furthermore, World Bank Report (2024) citing collection of
development indicators, puts the ratio of female to male labour participation rate in Nigeria at about 95.6%, this
figure indicate a relatively high female participation rate in the informal economy.
The ownership structure of most of the enterprises in the informal economy is sole proprietorship, and in a
number of cases with the assistance of unpaid family members and/or tenured apprentices. Another of the
noteworthy attributes of this sector is its broad activity spectrum that spans the entire segments of the national
economy. (Abumere, Arimah & Jerome, 1998). Apart from activity differential, the Nigerian informal sector
also has distinct gender and age segmentation. For instance, the informal manufacturing sub sector (food,
beverage and tobacco; wears and leather works; metal fabrication; paper and paper products, etc.), women
(58.5%) have a slight dominance over men (41.5%), whereas in the non-manufacturing (water supply; building
and construction; wholesale and retail trade; repair works, etc.), the reverse is the case with men (65.2%) which
is in a clear majority above women (34.8%). Moreover, male-headed enterprises are much more capital-intensive
than their female-headed counterparts and as such reported much more profit. For example, the proportion of
male-headed enterprises to female-headed ones that reported to be earning above N20’000 per month (or
US$2’335) is 95.4% to 4.6%, respectively. It has been identified that these informal sector enterprises are not
