**Japan and America**

 * Hypothesis:** The survivorship cove for both American and Japanese people will fit into the Type I cure, which is a late loss curve. Since U.S.A and Japan are both developed country, they have relatively strong and complete medical system and have enough food supply to feed people in the early and mature stage (reduce the mortality rate). However, the increase in morality rate for both may be caused by the pollution or the eating habit (particularly, for American, eat too much unhealthy food) of that country. Moreover, the increase in mortality rate also follows the natural principle of being birth and death.

The characteristic of the late loss curve is that mortality ( death rate) is very low in the infant and the early life stage and throughout most of the adult life and increase in old age life.

U.S.A http://freepages.genealogy.rootsweb.ancestry.com/~langolier/obituaries.html http://surnamearchive.com/1obits.htm http://www.latimes.com/news/obituaries/ Japan http://www.japantimes.co.jp/gsearch/gsearch.html?cx=partner-pub-4223870936880387%3Axbmt01-kzym&cof=FORID%3A11&q=obituary&sa=Search#0 Compare the graphs that I draw from my data with my hypotheses, we can only thta there is similarity between my graphs and the survivorship type II curve.The survivorship of humans in Japan does have a relative steady number of people alive during the early and middle age in life (from 0 to 60), which creates a smooth downward curve. After age 60, the morality rate of Japnese ebgins to increase in a more rapid rate, which creates a nice beautiful doward slope curve. The same situation also happens in the survivorship for humans in U.S.A. This may occur because the advance health cares system that both countries have developed. Due to both countries are developed country, they have better technology to produce a better quality of medical system which can cure people’s disease regardless of the difference ages in life. Through my data, we could also see that Japan’s old people mortality rate is lower than America. Japanese live longer than American. This might be affected by many factors. First, Japan is an island with many coastal areas trade of seafood. Therefore Japanese people end to eat more healthy food and live longer. Compared to America, American tend to eat less healthy food, therefore the mortality rate of Japan is lower than that of the US. The limitation of these graphs is that the data collected from the obituary online database does not represent a complete population of the whole country. It only represents partial population of the whole country. This happen may due to the person’s status of the society (famous or unknown, good reputation or bad reputation), the finical status (poor or rich, can afford the fee to post obituary in public), and the custom of the country. (Some country dose not have obituary). All these factors will determine and influence the accuracy of the database and the survivorship of a country. Also, this survivorship does not indicate the years of the population of a particular country. Maybe there is a famine in a particular and that will definitely affect the shape of the survivorship of a particular country. Another limitation factor is that it is not possible to investigate this experiment on the whole country considering every single person. Therefore, some assumptions were made since we had to assume that these results represented the whole population of both of these two countries. For example, this data is based on the number of obituary archives recorded in both of these two countries’ online database. There are always some people that did not register when they passed out or died without people knowing. Therefore, this data is not 100% accurate.
