Poverty has always been studied in a world of certainty. However, if the aim of studying poverty is not only improving the well-being of households who are currently poor, but also preventing people from becoming poor in the future, a new forward looking perspective must be adopted. For thinking about appropriate forward-looking anti-poverty interventions (i.e. interventions that aim to prevent or reduce future poverty rather than alleviate current poverty), the critical need then is to go beyond a cataloging of who is currently poor and who is not, to an assessment of households’ vulnerability to poverty. This study analyses a panel dataset on a representative sample of 150 rural households interviewed in 2007 and 2008 in the Amathole District Municipality of the Eastern Cape Province to empirical assess the dynamics of poverty and estimate the determinants of households’ vulnerability to poverty. The result of the study indicates that the number of vulnerable households is significantly larger than for the currently poor households; the vulnerability index was found to be 0,62 compared to 0,56 headcount index in 2008. This implies that while 56 percent of the sampled households are poor (ex post) in 2008, 62 percent are vulnerable to becoming poor (ex ante) in future. The result of the Probit model shows that the age, level of education and occupation of the household head, dependency ratio, exposure to idiosyncratic risks and access to credit are statistically significant in explaining a households’ vulnerability to poverty.
