The Relationship Between Males And Females

1. In cohort 1, the females have a lower survivorship curve, as indicated in graph 1. Moreover, around half of the population was dead in the 60-69 range. This makes the graph look somewhat close to a type 2 curve, but overall more similar to the type 1. In cohort 2, the graph (graph 2) shows the males and females having around the same curve early on, but then the males drop steeply. Although there is a definite curve in the two genders, the males appear to be closer to a type 2 than the females. The big drop in the males at 50 - 59 mark helps to enforce this idea. However, the overall shape of the graph is between type 1 and 2. Finally, cohort 3 (graph 3), indicates a very good example of a type 1 curve. Very few humans die early on, but …show more content…
Yes, the graphs indicate a difference of survivorship between the males and females. Surprisingly, the females had a lower survivorship in cohort 1, even though at that time, women didn’t have many unsafe jobs. However, there are some explanations as to why this occurred. One is that the women were constantly exposed to diseases and sickness due to their children getting sick and requiring help. Another reason is that childbirth in the 1800’s made women weaker and more susceptible to infectious diseases. Finally, women may have experienced malnourishment due to being a female, and being treated poorly. However, this trend left in cohort 2. Cohort 2 indicates an equal survivorship curve for the males and females up until the 50-59 interval, where the males drop severely. This can be attributed to the world wars. As stated before, cohort 2 is the most likely cohort where the population was affected since one couldn’t go to WW1 if they were born cohort 3. War only permitted males to enter, which is why the male’s survivorship declined in the later intervals. Finally, in cohort 3, the females have a higher overall survivability. This can be credited to their development of cardiovascular diseases. Since, many diseases are curable in this cohort, only the life threatening problems are left. However, women develop cardiovascular problems later in life, usually in their 70s and 80s. This is 10 years later than men, who develop them in their 50s and 60s. Since the onset of these problems are experienced later, there will be less females dying to this than men, increasing the female’s survivorship curve. Moreover, men make up most of the laborious and dangerous jobs, such as construction workers, which decreases their survivability even more. Generally, these factors are what allow the females to have a higher survivorship than
