Objective To quantitatively analyze the population aging and risk factors that affect the top ten causes of death and mortality in Kunshan City so as to achieve the purpose of correctly assessing the role of risk factors for each major cause of death. Methods The analysis of the top 10 causes of death and its mortality rate before and after the year of 1981 and 2000 was conducted to quantitatively calculate the role of population aging and risk factors among them. RESULTS: Aging is the top 10 cause of death and the increase in mortality. The risk factors are the top 9 causes of death and their mortality. Conclusion The increase of all causes of death, major causes of death, and death rates in Kunshan from 1981 to 2001 is due to the aging of the population. The aging of the population is the cause of each cause of death and its mortality. The risk factors are the main causes of death and the factors that reduce the mortality rate. The changes in the energy levels of the two factors determine the rise and fall of a cause of death and its mortality.
