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]
Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four indicate lack of data. Note: Rates below are per 1000 population. Location links are Demographics of LOCATION links.
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]
2012 United Nations projections show a continued increase in population in the near future with a steady decline in population growth rate; the global population is expected to reach between 8.3 and 10.9 billion by 2050. [122] [123] 2003 UN Population Division population projections for the year 2150 range between 3.2 and 24.8 billion. [67]
Population growth against time in a population growing logistically. The steepest parts of the graph are where the population growth is most rapid. The logistic growth equation is an effective tool for modelling intraspecific competition despite its simplicity, and has been used to model many real biological systems.
Latino Americans accounted for 51.1% of the country's total population growth between 2010 and 2020. [32] The Hispanic or Latino population increased from 50.5 million in 2010 to 62.1 million in 2020, a 23% increase and a numerical increase of more than 11.6 million. [32]

Consequently, the nation has an ageing population, with the median age of the country being 40.3 years. [15] In 2009, Russia recorded annual population growth for the first time in fifteen years; during the mid-2010s, Russia had seen increased population growth due to declining death rates, increased birth rates and increased immigration.
