This paper aims at measuring and analyzing for the first time the evolution of inequality in the distribution of expenditures among households in Togo over 2011-2015 and according to the characteristics of household heads. The study is based on the two most recent surveys (QUIBB 2011 and QUIBB 2015) and the monetary well-being indicator used is total expenditure per adult equivalent. With regard to the decomposition of the Gini index through Shapley's approach, within-groups inequality is greater than between-groups inequality for both years with an increase of total within-areas and within-age inequalities. The decomposition of overall within-groups component shows that urban areas, male-headed families and the 31-50 age group are more contributory. The increase of this contribution is observed for urban areas, the 31-50 age group while we have a slight decrease concerning gender. These findings witness that in Togo, policy actions to reduce inequalities should first target the within-groups expenditure disparities by focusing on the most contributory groups, and also without neglecting the between-strata effects. |
