Chapter 56, Problem 2TY
Summary Introduction
Introduction: Life table refers to a statistical table which shows the relation between life expectancy and mortality for a given set of people. Births and deaths related to the population can be calculated by studying the data depicted in the life table. The proportion of newborn and net reproductive rate can be calculated by analyzing the data provided in the life table.

he first involved an assessment of the relationship between cigarette smoking and incidence of lung cancer. For cigarette smokers, the lung cancer incidence rate was Ie = 200 per 100,000. For nonsmokers, the lung cancer incidence rate was Io = 25 per 100,000. The lung cancer incidence rate in the entire population was It = 100 per 100,000. The second study involved an assessment of the relationship between cigarette smoking and incidence of coronary heart disease. For cigarette smokers, the coronary heart disease incidence rate was Ie = 500 per 100,000. For nonsmokers, it was Io = 250 per 100,000. In the overall population, the coronary heart disease rate was It = 300.
1. What is relative risk the of developing lung cancer in the first study and of developing coronary heart disease in the second study? Interpret. 2. From the data involving cigarette smoking and lung cancer incidence, what are the attributable risk and the attributable-risk percent? Interpret the result. 3. From the…

- All of the following conclusions can be made about the population represented in the above age pyramid EXCEPT Select one: a. the wide base indicates a high birth rate b. death rates are only high in extreme old age c. the steep sides show the death rate is high for both the young and adults d. life expectancy is low with few people reaching old agearrow_forwardQUESTION 3 How could you identify a country that was in the postindustrial stage of demographic transition? a. The total population is low. b. Population growth is very rapid. c. There is a high birth rate. d. The birth rate may be lower than the death rate. e. Improved food production leads to drops in birth and death rates. QUESTION 4 Would a country with a high birth rate and a high immigration rate always have a growing population? a. Yes, because births and immigration increase the population size. b. Yes, because birth rate is the most important determinant of population growth rate. c. No, because it may have a low mortality rate. d. No, because it may have a low emigration rate. e. No, because it may also have a high death rate, emigration rate, or both.arrow_forwardTable 3.5 shows the number of deaths by age group in the United States in 2002 from all causes and incidents (unintentional injuries).
