As of 24 September 2010,the world population is estimated by the United States Census Bureau to be 6.871 billion.With just over 1.3 billion people (1,330,044,605 as of mid-2008),China is the world's largest and most populous country.As the world's population is approximately 6.8 billion,China represents a full 20% of the world's population so one in every five people on the planet is a resident of China.China's population growth has been somewhat slowed by the one child policy,in effect since 1979.
In the next few decades,India,the world's second most populous country is expected to surpass China in population.By 2040,India's population is expected to be 1.52 billion; that same year,China's will be 1.45 billion and India will become the world's most populous country.As of 2005,India has a total fertility rate of 2.8,well above replacement value,so it is growing much more quickly than China.
The current U.S.A.population is over 300 million people (303,500,000 in early 2008) so the United States has the world's third largest population (following China and India).
As the world's population is approximately 6.8 billion,the current United States population represents a mere 4.5% of the world's population so about one in every twenty people on the planet is a resident of the United States of America.
Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards.The last 50 years have seen a yet more rapid increase in the rate of population growthdue to medical advances and substantial increases in agricultural productivity,particularly beginning in the 1960s,made by the Green Revolution.In 2007 the United Nations Population Division projected that the world's population will likely surpass 10 billion in 2055.In the future,world population has been expected to reach a peak of growth,from there it will decline due to economic reasons,health concerns,land exhaustion and environmental hazards.There is around an 85% chance that the world's population will stop growing before the end of the century.There is a 60% probability that the world's population will not exceed 10 billion people before 2100,and around a 15% probability that the world's population at the end of the century will be lower than it is today.For different regions,the date and size of the peak population will vary considerably.
Human population control is the practice of curtailing population increase,usually by reducing the birth rate.Surviving records from Ancient Greece document the first known examples of population control.An important example of mandated population control is People's Republic of China's one-child policy.China has proclaimed that it will continue its one child policy,which limits couples to having one child,through the 2006-2010 five year planning period.
India is an interesting example of changes in government measures to control the country’s population.The Indian government,concerned that the rapidly growing population would adversely affect economic growth and living standards implemented an official family planning program in the late 1950s and early 1960s; it was the first country in the world to do so.Later extreme policies backfired with writers such as Salman Rushdie's Midnight Children lambasting forced sterilisation of petty convicts and incentivised sterilisation during the Indian Emergency (1975-1977).Later,policitians and press reports named Sanjay Gandhi as the policy's governmental head.
