A Study of the Relationship Between Lung Cancer Mortality and Smoking Rates

Abstract

While the crude mortality rate for lung cancer has been increasing year by year for both men and women, the age-adjusted mortality rate, which is calculated based on the base year population, has been decreasing since the 1990s. We will discuss the influence of specific generations on this peak in age-adjusted mortality rates by comparing age-adjusted mortality rates based on multiple base-year populations and by examining time-series trends in the percentage of the population in each 5-year age group in crude mortality rates.
