The trend line that I drew is curved and shows the relationship between Infant mortality rate and the GDP per capita of each country. It shows that the lower the GDP, the higher the infant mortality rate. When the GDP of a country is low then it shows that the country cannot afford high quality sanitation and medical expertise, as well as high quality education. When a country does not have access to good medical expertise then the baby could easily die while being born if it is not received properly or taken care of properly when it is born. Sanitation also plays a role in low child mortality rate because if the sanitation is low then there is a higher risk of disease. One more factor that could affect child mortality rate is if women are not well educated there is a higher chance of her not taking good care of her baby and cause its death. The countries tend to fall along the trend line and do not go too far from it.
Hi Tomi,
Your graph is great and you have done a good job of explaining the link between the two data sets. Do you think there is a point where the level of GDP becomes less important? Ie an amount over which infant mortality is just low?
