Results: Current drinkers were more concentrated among richer South Africans, while binge drinkers were concentrated among the poorer population. Changes in socioeconomic inequality in alcohol consumption between 20/15 were also assessed using the concentration index. Various equity stratifiers (sex, age, race, and rural/urban) are used to analyze the prevalence of alcohol consumption and to investigate differences in socioeconomic inequalities. Methods: Data come from the 2008, 2010/11, 2012, and 2014/15 waves of the National Income Dynamics Study (NIDS).
