A great deal of the time, mortality statistics take the place of the morbidity statistics because in many developed societies where people typically die from degenerative conditions, the age in which they die sheds more light on their life-time health. This produces many when looking at the pattern of sickness, but sociologists try to look at various data to analyze the distribution better. Normally, developing societies have lower life expectancies in comparison to developed countries. They have also found correlations between mortality and sex and age. Very young and old people are more susceptible to sickness and death. On average women typically live longer than men, although women are more likely to have bad health.
