Survivorship in Massachusetts from 1940 to 2010 Student’s Name Affiliation Course Instructor Date
Question 1 According to the population obtained from the census, the population in Massachusetts exhibits a relative increase in survivorship in cohorts between 1940 and 1990. When the two data sets are compared, survivorship trends in 1990 are slightly higher than in 1940. In 1940, the highest survivorship is experienced in the cohort 15-24 while in 1990 the highest survivorship is experienced in the cohort 25-34. The cohorts exhibiting the lowest survivorship include 75-84 & 85 and above in both years. This observation is as summarized in the graph below 0 2 4 6 8 10 12 0 2 4 6 8 10 12 14 16 18 20 Combined Survivorship curve for 1940 vs 1990 Graph 1: Combined Survivorship curve for 1940 vs 1990 Both curves exhibit a type I survivorship curve. Some of the attributed facts to this trend observed may include advancement in medical technology, developed immunity to some of the diseases causing high death rates among individuals, better healthcare provision, among other possible outcomes. Low survivorship is experienced in the cohorts 75-84 and 85 & above as a result of old age and the reduced immune system among the aged.
