Hello clouver,
Between 1930 and 1950, the population of Japan changed from 64,450,000
to 83,200,000 people, an increase of 29%.
During the 1930's, Japan experienced a sudden increase in population
growth, averaging about 1.5% increase per year throughout the
decade[1]. Between 1940 and 1945, however, the average annual rate of
growth decreased to 0.06%, although there is a marked increase in
fertility rate during the war years (caused by full employment and an
official policy encouraging childbirth) [2]. This decrease in growth
is probably due to deaths to warfare. During and after the war, the
male to female ratio changed from 100.6 men per 100 female in 1935 to
95.4 male per female in 1947. This indicated that many males were
killed in service during those years.
Immediately after the war, the nation experienced an increase in rates
of growth. Between 1945 and 1947, the average annual rate of growth
was 4.04%. Marriages during and before the war was considerably less
than before the war. Many young couples put off marriage until after
the war when the man in conscripted. In the years immediately after
the war, marriages almost doubled. The number of live births also
increased considerably during this period.
Between 1930 and 1950, the age distribution in Japan remained largely
unchanged. In 1930, 36.6% of Japanese were between 0-14 years old.
This percentage decreased to 35.4% in 1950. The 58.7% between 15-64
age group in 1930 increased to 59.7% in 1950. The 65+ age group
inched from 4.8% to 4.9%.
I hope that this answered your question. If you need clarification,
please request for it before rating this answer.
Thanks,
