International Mortality Comparisons
  • Richard MacMinnEdmondson-Miller Chair
  • Katie School
  • College of Business
  • Illinois State University

Opening comments
  • Data
  • The Human Mortality Database
  • Perspectives on international mortality data
  • Period data
  • Select birth cohorts
  • Rationales for mortality improvements

3
Objectives
  • Look for common trends in mortality improvement
    data
  • Identify select birth cohorts
  • Seek causal links for mortality improvements
  • Compare immediate annuity costs using historical
    mortality data

4
Select birth cohorts
  • A select cohort is a birth cohort characterized
    by greater rates of mortality improvement that
    previous and subsequent generations.
  • A number of select birth cohorts have been
    identified in the literature
  • England Wales (1925-45), Sweden (1900-10), and
    Japan (1910-20)
  • More select birth cohorts are noted here.

England Wales
  • There are some dramatic mortality improvements by
    period
  • The GAD identified generations born between 1925
    and 1945 as select birth cohorts.
  • Mean mortality improvements jumped from a max of
    1.8 to 3.8 for select cohorts.
  • The standard deviation jumped from .043 to .056

  • The next figure compares immediate annuity costs
    for different birth cohorts.
  • At each date the figure provides the cost for an
    immediate annuity that covers the individual for
    age 25 through 45.

Norway
  • There are some dramatic mortality improvements by
    period
  • Note the 1870s and late 1940s.
  • A 1940 select birth cohort has been identified.

Sweden
  • There are some dramatic mortality improvements by
    period
  • Note 1915-19 and the early 1940s.
  • 1925 and 1930 select birth cohorts have been
    identified.
  • The mean mortality improvement increased and the
    standard deviation decreased for the select
    cohorts.

  • There are dramatic positive and negative effects
    in the 1940s.
  • The 1915, 1930 and 1935 cohorts exhibit select
    properties.
  • The 1915 and 1935 cohorts exhibit higher mean
    mortality improvements and lower standard
    deviations that surrounding cohorts

  • There is a significant negative mortality effect
    in the 1960s similar to other countries.
  • The 1900, 1905, 1910, 1915 and 1935 cohorts
    exhibit select properties

Annuity comparisons
  • The figure provides a comparison of immediate
    annuity costs for Japan, England Wales and the
    United States

65
Annuity comparisons
  • The correlation between the change in costs is
    significant. The correlation between the
  • US and England Wales is 59
  • US and Japan is 52
  • England Wales and Japan is 33

66
Close
  • The mortality experience in the countries
    investigated exhibit similar trends from both a
    period and a cohort perspective.
  • The similar mortality experience is confirmed by
    the sizable correlation between the changes in
    annuity costs.
