Erreygers normalized concentration index (ECI) was utilized to evaluate socioeconomic inequality in knowledge about HIV. The variables that contributed to the observed socioeconomic inequality were determined using decomposition analysis.Results: We found the pro-rich inequality in knowledge about HIV (the weighted ECI was 0.16 with a Standard error = 0.007 and P value< 0.001). The decomposition analysis indicated that educational status (46.10%), wealth status (30.85%), listening to the radio (21.73%), and reading newspapers (7.05%) were among the contributors to the pro-rich socioeconomic inequalities in knowledge about HIV.Conclusion: Having knowledge about HIV is concentrated among rich reproductive-age women. Educational status, wealth status, and media exposure were the major contributors and should be a priority for interventions to reduce the inequality in knowledge about HIV.Keywords: socioeconomic inequality, concentration index, decomposition analysis, comprehensive knowledge, HIV/AIDS, sub-Saharan Africa
