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.
