Basic Cohort Mortality Analysis at Higher Ages : an Analysis of the Rectangularisation Process Based on Cohorts Born in 1890–1910 in the Czech Republic and France
Abstract
The aim of the article is to conduct a basic mortality analysis of persons aged 60 and over, focusing on the cohort perspective. The Czech Republic and France were selected for comparison.
Owing to data availability the analysis covered cohorts born in 1890-1910, where for each of the two countries it was possible to use data only from one particular source. Moreover, these cohorts can be assumed to be extinct today.
People in these cohorts reached the age of 60 and over starting in the year 1950, so it is also possible to study significant period effects on cohort data caused by developments in the second half of the 20th century. This approcah makes it possible to study mortality development at the highest ages while using the concept of rectangularisation of the survival curve, or mortality compression, as theoretical basis of the analysis.
The assumptions of this concept were not however fully verified for any of the studied populations.
