Japanese survival data

Description

This data frame contains information about the counts of dead Japanese by gender and year of birth (cohort), categorized by the whole part of age attained at death.

Usage

japanese

Format

A data frame with 1038 rows and 4 variables:

age

integer, age (to the smallest year) at death (in years)

byear

integer, birth year

count

integer, number of death for cohort at given age

gender

factor, the gender of the individuals; either male or female

Details

These data were obtained from the Annual Vital Statistics Report of Japan, released by the Japanese government every year since 1947. The authors note that "All the members of that cohort have died by the end of the observation period, a procedure referred to as the extinct cohort method". The data were obtained from the Human Mortality Database by the authors. Only positive counts are reported and two records (Misao Okawa and Jiroemon Kimura) are excluded because they do not correspond to the same selection mechanism.
