One of the reasons for the programme's success might be due to the value of the grant. Two-thirds of the income to the bottom quintile was provided via social assistance grants, with most of this income coming from child grants (the Child Support Grant, the Foster Care Grant and the Care Dependency Grant combined). The Namibian system of social CTs, which has its roots in South Africa, has evolved quite differently given the different economic and social circumstances in these two countries resulting in a mix of eligibility criteria being applied.
