Abstract
The study sought to investigate disparities in earnings across the geo-
political zone. Data were collected using the 2005 Labour Market
Survey of the National Manpower Board covering 19,888 Nigerian
workers: 2,297 in the North-East; 2,967 in the North-West; 3,714 in
the North-Central; 3,448 in the South-East; 3,088 in the South-South;
and 4,374 in the South-West. Sectors of employment were grouped
into private and public across the six national geo-political zones. The
research question raised was answered using descriptive statistics,
while the null hypothesis formulated was tested using One-way
Analysis of Variance (ANOVA) and Scheffe Post hoc analyses were used
to test for differences among the different geo-political zones. The sole
hypothesis was tested at the 0.05 level of significance. The results
indicated that there is a big difference between private sector and
public sector mean in all the geo-political zones. This implies that
public sector pays higher than private sector in all the six geo-political
zones. Also the hypothesis tested showed a significant difference in
workers’ earnings across the geo-political zones (R=0.03, F (5, 19,882)
=4.693, p< 0.05). These accounted for 3.4% of the variance in workers’
earnings. The study established that workers’ earnings differed across
the six geo-political zones in Nigeria; and also provided evidence of
disparity in earnings. This important finding gives the anecdotal
evidence and general perception of such disparities. It also gave us
insight into the differences in earnings on account of geo-political
zones which are being referred to as the native abilities of workers,
thus providing evidence of variation in earnings in the six geo-political
zones in Nigeria. Hence, the advocacy for policy and programmes for
closing the disparity gaps.
