THIS SPECIAL EDITION OF Enterprise Development and Microfinance is concerned with the question of investing in children born into and growing up in poverty – and how children in poor families and settings can better be supported to make successful transitions into good livelihoods and decent work as young adults. Across all regions, child poverty has long been an unduly neglected issue in national policy. Its implications for economic development have been underestimated and its impacts on societies, future prosperity, and for disadvantaged children themselves have been poorly understood. Within the global push toward poverty-reduction goals, the persistence of poverty among children needs to be addressed as an urgent priority. Children are by far the most vulnerable to poverty’s damaging effects: harms suffered by poor children, such as stunting in early childhood and learning deprivation, are hard to recover from in later years; such deprivations have major costs, not only for the young people affected but also for their whole societies; and poverty’s effects are powerfully transmitted to the next generation in turn. The elimination of extreme poverty among children cannot be safely left to the forces of economic growth alone. Particularly in quite unequal societies, rising average incomes may not translate powerfully into gains for the poorest children, while improvements in basic services, if they occur, may fail to reach the most deprived. Specific, strongly targeted interventions for the poorest families and children are needed to ensure that girls and boys and young people around the world are able to fulfil their potential, including as future entrepreneurs and wealth-creators. Of the more than 1 billion people currently living in extreme income-poverty, almost half are children, while in low-income countries, some 52 per cent of under-12s live in income-poverty, compared to 42 per cent of people over this age (Olinto et al., 2013). Rates of poverty are significantly higher among children compared to adults in many rich-world countries, too (UNICEF, 2012). Such patterns will continue unless there is a concerted focus on child poverty in its own right. Low family economic status is associated with poor outcomes and major deprivations in young lives. Children born in the lowest household wealth quintile in developing countries are over twice as likely to die before the age of five years as their counterparts in the top quintile, while the prevalence of malnutrition (low weight for age) among young children is about two-and-a-half times higher in the poorest families in developing countries compared to the richest (UNICEF, 2010). The physical stunting of children is not only a poverty trap for them as individuals; it also represents a fundamental squandering of human potential. It leads to long-term, largely irreversible damage – through poorer school performance, lower work capacity, and diminished adult productivity. Girls who suffer under-nutrition
