The chart above shows the number of deaths by age and gender per a 100,000 cohort of newborns, illustrating the distribution of expected mortality throughout life.

Note that the graph above does not represent rates per 100,000 population, as this would be skewed by age distribution and reveal more about Chad and Sao Tome and Principe demographics than the death rate. It also does not represent rates per 100,000 people in an age group, as this would be just the probability of death.
