Of course, this is just a theoretical estimation of the results. There may be a week or a year ago, the Earth has ushered in 65 million members; or one month later, the Earth 65 million citizens will be born in a corner of the world. But in any case, the Earth's population growth trend is an indisputable fact, on planet Earth to keep so many people have made greater challenges. The Agency also expects to 2012 United States Eastern time on October 16, 4: 36 pm (Beijing time 2012 on the morning of October 17, 5: 36), the global population will reach 7 billion; 2050 global population will increase to 90 billion.

The world's most populous of the five countries: China (13 million), India (11 million), United States (2.97 million), Indonesia (2.23 billion) and Brazil (1.81 billion).

States population growth and fertility, mortality, living standards, health and economic development, and so on, but over the past 50 years, there is also a phenomenon that is: in most cannot afford additional population of the fastest growing population. For example, in Africa and large parts of Latin America, women's average growth of 6-7 children. United States women's per capita have two children and meets the population zero growth, but the United States the reproductive migration persistent high volume. But in general the more developed in Europe, the average number of births only 1.4, individual countries have negative population growth.
