Population projection is a scientific attempt to peep into the future population scenario, conditioned by making certain assumptions, using data relating to the past available at t hat point of time.Assumptions used and their probability of adhering in future, forms a critical input in this mathematical effort. Predicting the future course of human fertility and mortality is not easy, especially when looking beyond much further in t ime. Medical and health intervention strategies, food production and its equitable availability, climatic variability, socio-cultural setting, politico-economic conditions and a host of other factors influence population dynamics, making it a somewhat unpredictable exercise. Therefore, much caution must be exercised when either making or using the population projections and the context of various conditions imposed, should not be lost sight of on the basis of past behaviour and the likely future scenario assumed.
The Population Reference Bureau is reporting on the release of preliminary data from the United Nations Population Division projecting population in the year 2100. The United Nations expects India, which is likely to surpass China as the world's largest country by 2030, to reach more than 1.55 billion people in 2100. Here's the list of the world's largest countries in 2100...
- India - 1,557,468,000
- China - 944,380,000
- Nigeria - 756,007,000
- United States - 478,047,000
- Tanzania - 314,197,000
- Pakistan - 262,149,000
- Indonesia - 254,590,000
- Democratic Republic of the Congo - 212,000,000
- Philippines - 178,256,000
