Infant mortality rate is the number of babies who die before the age of one per thousand live births per year. Infant mortality rate shows how countries survival rates vary due different stages of development. A high Infant mortality rate may indicate insufficient healthcare resources such as low levels of food available, leading to a lower calorie intake as well little numbers of nurses available per person. It may also indicate the prevalence of fatal diseases such as HIV/AIDS and Malaria, more commonly found in less economically developed countries. The opposite can be assumed from low infant mortality rates.
