This implies that about 5.6 billion people in the world are vulnerable to various degrees. Despite working, they cannot earn enough to get out of poverty. In many developing countries, most poor adults have to work, if only to survive, especially in the absence of adequate social protection. Of the world’s poor, 75 per cent live in rural areas where agricultural wage workers suffer the highest incidence of poverty, largely because of seasonal unemployment and the low wages paid by small farms (World Bank, 2009b).
