This is because they know that not all of their children will survive as they do not have access to facilities such as hospitals and doctors. Knowing that not all of their children will survive, they have more children. The reason it is common for children under the age of five years old to die in these countries is because their parents do not have enough income to buy food. These countries also do not have great agriculture; the climate is too dry, wet or hot to grow their own crops. You can also notice that most of the countries that have a low child mortality rate and a low amount of children per woman are developing countries. This would be because developing countries have the facilities like hospitals and doctors that the developing countries do not have. A third variable that would relate to the child mortality rate and the amount of child per woman is life expectancy (graph 5). What is noticeable from graph 5 is that all the countries that have
