Abstract
This publication provides a multidimensional assessment of earnings inequality in the world of work using harmonized ILO microdata. It examines vertical inequality through relative and absolute measures, horizontal disparities across demographic and labour‑market groups, and inequality of opportunity driven by circumstances beyond individual control. The findings show that Sub‑Saharan Africa and Latin America consistently exhibit high earnings inequality, with absolute measures revealing particularly wide material gaps. Decomposition results highlight the large role of sectoral differences and employment formality, while demographic characteristics such as sex contribute less to between‑group inequality but remain important when considering intersecting disadvantages. Inequality of opportunity accounts for a measurable share of wage dispersion, underscoring persistent structural barriers. The publication also analyses earnings among own‑account workers, revealing substantial within‑group inequality, especially in the informal economy. Overall, the results underscore the need for comprehensive labour‑market policies that address structural segmentation, expand formal employment, and improve access to decent work.
