The Civil War that lasted from 1861 to 1877 was mainly caused by the diverging society between the North and the South. The North and the South had different goals. There were many factors that led to the war and the chief ones were political and economic differences between the North and the South.

This study was done to determine and compare the suvivorship curves of people who

died prior to1945 and after 1945. Many medical advances have been made in this

country since 1945. We have developed many new drugs, vaccines, and medical

equipment that have aided in prolonging and saving lives of humans. We have also

developed many new techniques to test for diesases and this helps people get the

proper medical attention before the disease gets to the point where it can no longer be

controlled.

I would think that the general belief of most people is that the survivorship of mankind

would have dramatically increased after 1945 because of how far science has come in

that time. The lifespan of humans throughout history has gotten longer, because of

medical advances. The deaths of the people studied will most likely not only be from

disease or sickness but other causes, such as war, violence, drugs, automobiles, etc.

Methods & Materials:

We received a data sheet to collect the data from our findings. The sheet is two-sided,

with blank columns to record the male and female individuals and the age of their

death. The age of death column is divided into five year intervals. One side of the

sheet is to collect the information for those that died before and in the year1945. The

second side is for the data of those that have died after the year 1945.

We went to the Cullowhee graveyard to collect the data off of all of the gravestones in

the cemetary. Since the graveyard is so big and not in exact rows, we had to be sure

that be would not contaminate the data and duplicate the headstones, so we roped off

the sections to be sure not to. When examining the headstones, we looked at the

headstone and determined if they were male or female, by the name or markings on the

headstone. Second, we looked at the date of death to determine which class to put

them in. Third, we subtracted the year of death from the year of birth to determine the

age...
