According to estimates by the United Nations, the world population is 6 billion people in 1999 and 6.89 billion people as of July 1, 2011, but according to Hania Zlotnik of the United Nations Economic and Social Affairs Population Division, It seems that it is believed to reach 7 billion people on October 31. However, it is said that this date is only half talk level.

The world population is about 1 billion people around 1800 and finally increased to 2 billion people in the 20th century (in 1930). However, in 1974 it was only 44 years to reach 4 billion people, and 6 billion people in 1999 it will take only 25 years, which is even shorter.

Dr. David Bloom of Harvard University published in Science magazine "7 Billion and CountingAccording to the survey results titled "The flow of population continues as the death rate decreases and the birth control is delayed. In 1950, 68% of the world's population was from developing countries, but in 2050 this proportion is expected to extend to 86% and the world population in 2050 is estimated to have increased by 2.3 billion , But 97% of them seem to be in developing countries.

Currently, the country with the largest population is 1.35 billion in China, but it decreased to 1.3 billion in 2050. Meanwhile, India, which is now the second-ranking company with 1.24 billion people, has increased to 1.69 billion people, and the number 3 (311 million people) currently in third place is expected to increase to 423 million people In Nigeria, which is currently ranked fourth, the population of 166 million people is expected to explode to 20 million in 2050. Japan and Russia whose names are included in the top ten are thought to be disappearing from the ranking in 2050.

The birthrate has declined worldwide from 5 to 2.5, but regional disparities exist. In response to the question "How many children are ideal?", Responses of 1.6 in Austria and 2.4 in the UK were obtained, while answers of 5.3 in Uganda and 9.1 in Niger have been obtained.

As the population increase increases, it becomes necessary to solve the problem of distributing food and water. There are also problems concerning housing and energy supply. In order not to increase the population, the birthrate must be lowered, but the birthrate decline policy due to contraception etc. in developing countries has not been quite effective, while in advanced countries the aging of the population is accelerating due to the declining birthrate It says.

Dr. Bloom says, "It is easy to pretend not to look at these difficult problems, but there are a lot of difficult problems to be addressed."
