INTRODUCTION To begin with I would like to define child mortality. Child mortality can also be known as the death of an infant, baby or as child. The pleasures of life are worth nothing if one is not alive to experience them. Through the twentieth century in the United States and other high-income countries, growth in real incomes was accompanied by a historically unprecedented decline in mortality rates that caused life expectancy at birth to grow by nearly 30 years (Cutler et al., 2006). In poor countries, that is the less developed countries which are mostly in the sub-Saharan Africa about 30 percent of all deaths occur in childhood compared with just 1 percent in the richer that is developed countries (Cutler et al 2006). The determinants of mortality change in less developed countries are not easy to unravel. Improvements in health technology and availability are evidently relevant; education certainly plays an important part; sanitation, clean water supply and a host of other environmental variables have undoubted effects.( Rodgers 2002).
Conventional methods of classifying causes of death suggest that about 70% of the deaths of children (aged 0-4 years) worldwide are due to diarrhoeal illness, acute respiratory infection, malaria, and immunizable diseases (Pelletier et al 1995). A question of long standing policy interest concerns the extent to which reducing poverty will lower the risk of child mortality( Bhalotra 2010).Much of the literature on consumption smoothing and on risk sharing has focused on the ability of the household as a unit to protect its consumption.(Dercon and Krishnan 2000). In recent years a large literature has arisen which estimates the effect of household on the health and mortality of children in developing countries (Pitt 1997). Hence the importance of household cannot be over emphasized.

Household income is the income that accounts for the income of all residents in each household in form of
