The world’s population

To get a macro understanding for a task, we visit the Japanese Bureau of Statistics website.  This site has a page on world population and the content is taken from the United Nations Statistic Division. 

We’d like to show the shifts taking place in the world’s population.  Below are the populations for the top 10 countries in 2009.

China                               1.35 billion            Male 700 million    Female 650 million

India                                1.2 billion               Male 620 million    Female 580 million

United States                315 million            Male 155 million    Female 159 million

Indonesia                   230 million         Male 115 million    Female 115 million

Brazil                           194 million               Male 95 million      Female 98 million

Pakistan                      181 million                Male 93 million      Female 88 million

Bangladesh                  162 million               Male 82 million      Female 80 million

Nigeria                         155 million               Male 78 million      Female 77 million

Russia                             141 million               Male 65 million      Female 76 million

Japan                              127 million               Male 62 million      Female 65 million

The 2050 population estimate is below.  *The website also lists a 2025 forecast. 

India                              1.61 billion              Male 820 million      Female 790 million

China                             1.41 billion               Male 730 million   Female 680 million

United States             400 million             Male 200 million       Female 200 million

Pakistan                      335 million            Male 171 million      Female 164 million

Nigeria                          289 million            Male 146 million      Female 144 million

Indonesia                         288 million            Male 142 million      Female 146million

Bangladesh                         222 million            Male 111 million      Female 111 million

Brazil                                  219 million             Male 106 million    Female 113 million

Ethiopia                              174 million              Male 87 million       Female 87million

Democratic Republic of the Congo   148 million     Male 73 million       Female 74 million

The world population is estimated to be 6.83 billion people in 2009 and 9.15 billion in 2050. 

One possible reason that India will overtake China is China’s “one child policy,” which has been in effect since 1979.   The policy may also explain the difference in China’s male to female ratio.  In India, the male to female ration difference may come from the fact that males are preferred from the labor and manpower standpoint.  Also, it has been pointed out that for women, families must come up with expensive dowries during weddings.    Some feel that the gender discrimination problem also has an impact.  If the predictions are correct, this will mean that in 2050 approximately 50 million Chinese men and 30 million Indian men will be unable to marry.  China will also be facing the problems associated with becoming an aging society.  

Recently, the United States has also become a topic in the population discussion.  It is being said that in 2050 the number of Hispanic residents will reach approximately 100 million.  *Population growth is also affecting the United States.  In Europe, countries are facing dwindling birthrates and aging populations as well as increasing numbers of immigrants.  The number of people with Arab backgrounds also continues to increase. 

Countries known as “developed nations,” are beginning to take measures for aging populations (or already aged societies).  Population growth is considered one of the contributing factors for economic growth.  What should be done in Japan?  Japan’s 2050 population is expected to be approximately 90 million.
