Laryngeal cancer mortality age-standardized rates (ASRs), using 1985 Japanese standard population, are shown for Japan, USA, UK, France and Italy (Fig. 1). In all of the countries, males have higher ASRs compared with females. For males, ASRs have been decreasing since 1970s in Japan and France. ASRs in the other countries have been gradually decreasing in recent years. For females in Japan, ASRs drastically decreased until 1990 and since then have been slightly decreasing. In Italy, a mild decreasing trend is observed after the middle of the 1980s. In the USA, ASRs increase until 1980. The others remained roughly flat for four decades.

Mortality trends in males are shown by age group according to
year of death (
Fig. 2). In Japan, the USA and the UK, decreasing
trends are observed among age groups under 70 years old. In
France and Italy, mortality rates are higher than in the other
three countries for all age groups and there are decreasing
trends after passing peaks between 1970 and 1980. Japan has
the greatest difference in mortality rates between the 40–44
and 85+ age groups, while France and Italy have only a small
difference between those age groups. Mortality trends in females
are shown by age group according to year of death (
Fig. 3).
In Japan, mortality rates have been decreasing for all age groups.
There is no obvious trend in the other countries.

Mortality trends in males are shown by age group according to
year of birth (
Fig. 4). In Japan, mortality rates decreased
from the birth cohort born in 1900 onwards. In the USA, a mild
decreasing trend is observed from the birth cohort born 1920.
In the UK, mortality rates have been decreasing with the birth
cohort born before 1920. After the birth cohort born in 1920,
however, a decreasing trend is not observed. In France and Italy,
mortality rates in the 40–64 age groups exhibit a peak
with the birth cohort born around 1930. Mortality trends in
females are shown by age group according to year of birth (
Fig. 5).
Decreasing trends are observed from the birth cohort born
in 1900 in all of the countries except the USA. In the USA,
as well as for the 40–64 age group for males in France
and Italy, there is a peak in mortality rates with the birth
cohort born around 1930.
