In biology, population growth is the increase in the number of individuals in a population. The population growth rate is the rate at which the number of individuals in a population increases in a given time period as a fraction of the initial population.Global human population growth amounts to around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing, where estimates have put the total population at 8.4 billion by mid-2030, and 9.6 billion by mid-2050. The top five nations which have majority of the population are China, India, USA, Indonesia and Brazil. Vatican City and Pitcairn Islands are the least populated countries in the World.
All of us know few causes for over population are :
1) Causes of Overpopulation
2) Rise in the Birth Rate
3) Migration
4) Lack of Education
5) Demographic transition
The family planning policy, known as the one-child policy in the West.The term "one-child" is inexact as the policy allows many exceptions and ethnic minorities in China are exempt. In 2007, 36% of China's population was subject to a strict one-child restriction. An additional 53% were allowed to have a second child if the first child was a girl. In November 2013, following the Third Plenum of the 18th Central Committee of the Chinese Communist Party, China announced the decision to relax the one-child policy. Under the new policy, families can have two children if one parent is an only child.This will mainly apply to urban couples, since there are very few rural only children due to long-standing exceptions to the policy for rural couples. Family planning in India is based on efforts largely sponsored by the Indian government. In the 1965-2009 period, contraceptive usage has more than tripled (from 13% of married women in 1970 to 48% in 2009) and the fertility rate has more than halved (from 5.7 in 1966 to 2.4 in 2012), but the national fertility rate is still high enough to cause long-term population growth. India adds up to 1,000,000 people to its population every 20 days. India suffers from the problem of overpopulation. Although the fertility rate (average number of children born per woman during her lifetime) in India has been declining, it has not reached replacement rate yet. The replacement rate is defined as the total fertility rate at which newborn girls would have an average of exactly one daughter over their lifetimes. In more familiar terms, women have just enough babies to replace themselves. Factoring in infant mortality, the replacement rate is approximately 2.1 in most industrialized nations and about 2.5 in developing nations (due to higher mortality). Discounting immigration and population momentum effects, a nation that crosses below the replacement rate is on the path to population stabilization and, eventually, population reduction.
The Family Planning Association of India, abbreviated as FPA India, is a registered charity in India. Established in 1949, the organization has 40 local branches across the country that promote sexual health and family planning.It is the national affiliate of the International Planned Parenthood Federation. This is a list of the States of India ranked in order of number of children born for each woman. Based on this study,the following Indian states,if they continue their current trends of fertility rate or lower them further, would stop contributing to population growth in India in future - Andhra Pradesh, Goa, Tamil Nadu, Himachal Pradesh, Kerala, Punjab, West Bengal, Maharashtra, Delhi, Jammu And Kashmir, Karnataka and Sikkim. This is a list of Major States of India ranked according to unemployment. The list is compiled from the NSS(66th round) Report from Ministry of Statistics and Programme Implementation, Government of India.Data is unavailable for NE region and smaller States.Kerala has the highest unemployment rates and ranks worst, while Rajasthan and Gujarat has the least unemployment rate among major States of India. (Higher ranks represents higher unemployment among the population). National average stands at 50.
This is a list of Indian states ranked by the status of effective coverage of supplementary nutrition program for children. The figures come from the 2011 Evaluation Report on Integrated Child Development Services (ICDS) published by Planning Commission, Government of India. Mizoram, Karnataka, Jammu and Kashmire West Bengal and Gujarat are first five states as per of ICDS
