Introduction Consistent positive economic growth post-1994 BUT what has the impact of this positive growth been on social welfare? Evidence from 1995 – 2000: no major shifts in poverty levels, but increase in inequality Release of the 2005 IES enables a 10 yr overview AIM: 1.Poverty and Inequality Shifts: 1995 – Impact of economic growth on poverty & inequality: Exploring the interactions
Data and Methodology 1995 and 2005 Income and Expenditure Surveys All measures are individual poverty and inequality measures, calculated using per capita total household expenditure Based on the standard FGT class of poverty measures and two standard poverty lines (R322/”cost of basic needs” and R174/2$ a day in 2000 prices) Poverty shifts without poverty lines (Cumulative Distribution Functions) Inequality measures: Gini Coefficients, Theil-index, Lorenz Curves

Poverty lines are in 2000 prices 2.At both poverty lines, the changes in the headcount rate are statistically significant at the 5 percent level at the aggregate and for Africans (indicated by the shaded cells) 3.The population in 1995 has been weighted by population weights according to the 1996 Census. The population in 2005 has been weighted by the household weight multiplied by the household size. The 2005 weights are based on the 2001 Census

Relationship between Growth, Poverty and Inequality Growth a necessary but not sufficient condition for poverty reduction What is the role of inequality in the growth process Utilise GIC methodology to examine GPI interactions

Determinants of Growth in Expenditure of the Poor since 1995 Impact of Social Grants Number of beneficiaries has increased from about 3 million in Aug 1997 to 9.4 million in April 2005 Driven by the extension of the Child Support Grant (< 1 million in 2001 to 5.6 million in 2005)

In both datasets, the population has been weighted by the household weight multiplied by the household size.
Conclusions Poverty: Significant (at 5 % level) decline in absolute and relative poverty at the aggregate, for African- and female-headed HHs: Shift is invariant to choice of any feasible poverty line Inequality: Income Inequality: Significant increase (at 5 % level) in Gini coefficient at national level Theil results suggest that inequality between race group component has become more important in explaining inequality shift.
Growth Incidence: Absolute pro-poor growth evident Large changes at the top end....the “missing middle”? Rise in incomes at the bottom end of the distribution Nature of the Growth Path: The incomes of those at the bottom of the distribution are supported through social transfers: is this a desirable and/or sustainable growth and development trajectory? Conclusions
