Estimating abridged life tables using alternative methods : a comparative study
SubjectΘνησιμότητα -- Στατιστική
This comparative study involves the construction of abridged demographic life tables, a basic methodological tool used in Demography and Actuarial Science for the study of mortality. For the purpose of the analysis we use vital statistics on deaths registered during the period 1998-2003 and population counts derived from the 2001 population census of Greece. The analysis focuses on six different local areas (Municipalities) with ver different population size. The above tables were obtained using four well-established assessment methods (Even Distribution of Deaths, Reed-Merrel, Greville, and Keyfitz) that calculate the death rates and other survival table functions by age and gender. Comparing the results obtained using the above mentioned methods for each Municipality showed little differences between them. Hence, this gives us the choice of any of the above methods in constructing compact survival tables.
