Human Population – Changes in Survival

I. Abstract
The purpose of this lab was to determine how changes in human mortality and survivorship have influenced population growth.

People today are living longer than they did a hundred years ago. This can be contributed to the advances in modern medicine and lifestyle changes. We as a society are taking better care of our elderly. We have government funding to help those who cannot help themselves.

This mass population growth is seen by some people to be in line with the sustaining of the global environment. But how can we continue producing millions of children each year, and still support plant growth and clean air?

III. Materials and Methods
To find out the population growth of a certain area (namely my home town of Powell, Tennessee) I visited a local cemetery to record data from the headstones. The information I collected was sex and age at death. I then charted these findings to establish the number of male and female deaths during a certain century, and the average age of each at the time of death. I also obtained local newspapers to record the deaths from the past two weeks. I then charted these with the same information.

IV. Results
After spending considerable time at the local cemetery, and looking through a couple of weekly papers, I took the information that I had recorded and formulated excel spreadsheets to show the results. These charts are included with this report.

V. Discussion
I found that there are varying ages of death in each date category, but for the most part, the ages increased considerably from century to century. This, to me, would be a sign of the technology progression that we have experienced and the modern medical discoveries to aid in the healing processes of some previously fatal diseases.

There are millions and...
