Human Lifespan

Paper Summary:

This paper explains that, since a cohort analysis of human lifespan is impractical, a static analysis of human lifespan was performed using data collected from local graveyards and obituaries of persons who died from 1930 to 1939 and from 1990 to 2006. The author concludes that, when survivorship curves for each period were plotted against each other, the curve from 1990 to 2006 was greater for nearly every age group; therefore, it can be concluded that the demographic data show an increase in lifespan for both males and females from the 1930s to the present. The paper concludes that decreased mortality rates in the United States are due to advances in preventative medicine, more advanced and targeted treatments of disease, lower incidence of disease due to vaccination and better education.

From the Paper:

"Once over 1366 data points were collected and checked for duplicate data, it was put into Microsoft Excel and the age of each individual was calculated using the formula year of death minus year of birth. The data was then separated into two groups based on the date of death and this was plotted into various graphs to better analyze the results. Two static life tables were constructed, using this data, which contained survivorship (lx), mortality rate (mx), and survival rate (sx) of all the individuals in each group and then another four tables were made by separating male and female data points in each group. Survivorship intervals were spaced from 0 to 0.99 years of age, 1 to 9.99 years, 10 to 19.99 years, and so on until 100 years of age."
