Globally, the rate of population growth has declined from a peak of 2.2% per year in 1963. [9] Population growth alongside increased consumption is a driver of environmental concerns, such as biodiversity loss and climate change, [10] [11] due to overexploitation of natural resources for human development. [12]
Annual world population growth peaked at 2.1% in 1968 and has since dropped to 1.1%. [1] According to the most recent United Nations' projections, the global human population is expected to reach 9.7 billion in 2050 and would peak at around 10.4 billion people in the 2080s, before decreasing, noting that fertility rates are falling worldwide.
The practice, traditionally referred to as population control, had historically been implemented mainly with the goal of increasing population growth, though from the 1950s to the 1980s, concerns about overpopulation and its effects on poverty, the environment and political stability led to efforts to reduce population growth rates in many ...
Human population projections are attempts to extrapolate how human populations will change in the future. [2] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [3] Models of population growth take trends in human development and apply projections into the future. [4]
Graph of world population over the past 12,000 years . As a general rule, the confidence of estimates on historical world population decreases for the more distant past. Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census.
Population Control: Real Costs, Illusory Benefits is a nonfiction book by Steven W. Mosher, president of the Population Research Institute, first published in 2008. Population Control is a detailed exposition on the global effort to combat overpopulation , arguing that not only population control is immoral in many cases, but that ...
The number shown is the average annual growth rate for the period. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship—except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of the country of origin ...
However, world population growth is unevenly distributed, with the total fertility rate ranging from the world's lowest of 0.8 in South Korea, [10] to the highest of 6.7 in Niger. [11] The United Nations estimated an annual population increase of 1.14% for the year of 2000. [12] The current world population growth is approximately 1.09%. [5]
