Socioeconomic Analysis of Gender Disparities in Occupational Outcomes for Mine Workers in Rivers and Bayelsa States, South South Nigeria

Gender disparities in occupational outcomes within extractive industries remain a persistent feature of labour markets in Nigeria's South South geopolitical zone, where mining and allied sector employment is strongly sex-segregated. This study analyses gender-based disparities in wages, occupational safety exposure, career advancement, and employment security among mine workers in Rivers and Bayelsa states. A stratified random sample of 320 workers, balanced by gender, was drawn from 14 operations including sand dredging, aggregate quarrying, and oil sands extraction activities. Structured questionnaires supplemented by in-depth interviews with 20 workers and eight human resources managers were employed. Statistical analysis used OLS wage regression controlling for education, experience, and occupational grade, alongside qualitative thematic analysis. A gender pay gap of 28 percent was identified after controlling for human capital variables, attributable partly to occupational segregation and partly to unexplained within-grade differentials. Women in the sample are disproportionately employed in surface support roles with lower injury rates but significantly lower earnings. Career advancement opportunities are reported as severely limited by gender-based social norms and the absence of mentorship structures. The study recommends gender pay audit requirements for mining licence holders, targeted women's leadership development programmes, and gender-disaggregated occupational health monitoring.
