The Effects of Demography in Political Perspective :Demographic Change in Japan between 2000 and 2030

Introduction

Introduction

  • In this report, we will overview the demographic change in Japan between 2000 and 2030, referring to the 12th Japanese Population Projections, January 2002, by the National Institute of Population and Social Security Research (NIPSSR), for the new ones are under preparation for announcement in next year.

  • The 13th projections will be adjusted to recent fertility trend in Japan, based on the results of the 2005 population census and the Vital Statistics.

  • However, long-range basic trend will be not different from the 12th projections.

  • After reviewing the demographic changes in Japan, we will show some speculations on their effects in political perspective .


Trend of the total population

Trend of the Total Population

peak :127.74 million in 2006

(in fact: in 2004)

100.6 million in 2050


Trend of the total population in succession

Trend of the Total Population (in succession)

  • The population is expected to gradually increase in subsequent years, reaching its peak of 127.74 million in 2006, then enter a longstanding depopulation process.

  • The population is expected to drop to the size in 2000 by 2013, then decrease to about 100.6 million in 2050.

  • It is now well known to have already reached its peak in 2004, two years in advance.

  • After then, the expression of Depopulation Society is getting popularity in Japanese Media.


Trend of the total fertility rates tfr

Trend of the Total Fertility Rates (TFR)

1.31 in 2007

1.36 in 2000

1.25 in 2005

1.39 in 2049


Trend of the total fertility rates tfr in succession

Trend of the Total Fertility Rates (TFR) (in succession)

  • Assumption for the Medium Variant: TFR will decline from 1.36 in 2000to 1.31 in 2007. Thereafter, a gradual upward change is predicted, and in 2049 the rate will be 1.39.

  • Assumption for the High Variant:TFRwill turn upward immediately from 1.36 in 2000, reaching 1.63 in 2049.

  • Assumption for the Low Variant: the continues to decline from 1.36 in 2000, reaching 1.10 in 2049.

  • Infact, TFR in Japan continues to decline from 1.36 in 2000, having reached already1.25(ref.. 1.31 of assumption in Mv., 1.36 in Hv. and 1.22 in Lv.) in 2005.

Trend of the Survival Rate (Future Life Table)

male :78.11( 78.64)Female85.20( 85.59) in 2005

male : 80.95Female89.22 in 2050


Trend of the survival rate future life table in succession

Trend of the Survival Rate (Future Life Table)(in succession)

  • According to the future life tables, the life expectancy, 77.64 years for males and 84.62 years for females in the year 2000, is expected to extend to 78.11 years for males and 85.20 years for females in 2005, 79.76 years for males and 87.52 years for females in 2025, and, in 2050, 80.95 years for males and 89.22 years for females.

  • According to the Vital Statistics in Japan, the life expectancy, 78.64 years for males and 85.59years for females is recorded in 2005.


Trend of the international migration rate

Trend of the international migration rate

Males 20-60:net migration rate <0

  • Because international migration for Japanese population is relatively stable, the assumptions were made as follows: first, obtain the average value of the annual net international migration rate between 1995 and 2000, and adjust the rate to remove the blurring which occurs due to random fluctuation as constant for 2001 onward.

Females 20-60:net migration rate >0


Population trend for three major age groups

Population Trend for Three Major Age Groups


Trend of the proportion of three major age groups

Trend of the Proportion of Three Major Age Groups

Working-age (15 to 64) population :53.6 %

Aged(65 and over)

population :35.7%

Child Population (aged under 15): 10.8%


Aging population

Aging Population

  • Child Population (aged under 15):According to the medium variant projection, is expected to shrink from the current 14.6% level (2000) to the 14% mark in 2005, and eventually down to 12.0% in 2021. The downward trend continues to 11.0% in 2036, and by 2050, the percentage is expected to be around 10.8%.

  • Working-age Population (15 to 64) started falling in 2000 at 68.1%, and is expected to reduce to 60.0% in 2020 .The decline continues on slowly to 10 points lower than the current standard in 2035 at 58.0%, 54.9% in 2043, and eventually to 53.6% in 2050.

  • Aged Population (aged 65 and over) will grow from the current 17.4% (2000) to the 25% range in 2014. It will eventually reach the 30 plus-percent range in 2033. The increase persists, reaching 35.7% in 2050.

The effects of demography in political perspective

The effects of Demography in Political Perspective ?

  • Falling down of local communities and hyper-concentration to metropolitan area→Becoming Japan as City States ? (a wider-area local government system)

  • ●地域社会の崩壊→大都市圏への集中化→都市国家化する?

  • Expanding Income-gaps/Reduction of Middle Class Population, Globalization of Japanese Elite /Developing AI-Robots Technology ●格差の拡大/エリート層の相対的縮小・国際化/人工知能化・ロボット化

  • World-leading Consumer Market as the most Aging Society in the human history ●高度消費社会としては世界の先端を行くだろう。

The effects of Demography in Political Perspective ?

  • Short coming and Import of Human Resource for further Technological Innovations ●技術革新など人的資源の不足と輸入?

  • Short coming of Human Resource for political Innovations:Ultra-Conservative Society.40% of votes belong to Aged Population (aged 65 and over) . ●政治的なパワーの担い手? 選挙? 社会の保守化:有効票の過半数が老人票

  • Spiritually radical Nationalism and facturally Timidity in Asian Deplomacy ? ●精神的な意味ではナショナリズムを強調・実態としては弱腰:東アジアのリーダーシップは取れないだろう。
