The purpose of the study was to estimate the accuracy of death rates that were reported officially. For this purpose, the effects of the structural change of population on mortaity level were analyzed by comparing the age-standardized death rate and crude death rate. The major findings of the study were as follows: Based on the Vital Registration Statistics, the population of target years were standardized year 1966, 1980, 1994. The effects of structural change of population on mortality level were measured as 30.7%, 72.6%, 109.0% during the period 1996-1980 while they were 49.8%, 69.5% and 87.6% respectively during the period 1966-1994. Thesame analysis was conducted on the basis of Census data. The effects were 49.6%,100.0%, 65.4% during the period 1966-1980 while those were 27.6%, 58.7% and 22.8% during the period 1966-1994. Based on the data applied by the crude death rate, the populations of target years were standardized on the standard year 1966, 1980,1994. The results indicated that the effects of structural change of populations on mortality level were 62.3%, 42.6%, 26.0% during the period 1966-1980 while they were 56.0%, 50.8% and 45.4% during the period 1966-1994. There were large differences in crude death rates and age-standardized death rates among these data sources: Vital Registration statistics, Census Data, Data applied by Crude Death Rate. These differences imply that the mortality statistical data collected through the reporting have many problems in terms of the accuracy and reliability.
