Abstract
Age-period-cohort analysis has received much attention recently. It has been a popular epidemiologic tool since Frost [6] employed it in his study by graphical displays. In past two decades, the statistical techniques are applied to the analysis of temporal factors: age, period and cohort.

The objectives of this study are to examine how the effects of age at death, calendar period of year and birth cohort contributed to lung cancer mortality in Hong Kong over the period of 1970-1994 and to predict the mortality rates due to lung cancer from 1995 to 2014. Three projection methods are introduced to determine the future lung cancer mortality rates.
