Globally, the rate of population growth has declined from a peak of 2.2% per year in 1963. [8] Population growth alongside increased consumption is a driver of environmental concerns, such as biodiversity loss and climate change, [9] [10] due to overexploitation of natural resources for human development. [11]
The 2022 projections from the United Nations Population Division (chart #1) show that annual world population growth peaked at 2.3% per year in 1963, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and could drop even further to minus 0.1% by 2100. [4]
The Demography of the World Population from 1950 to 2100. Data source: United Nations — World Population Prospects 2017. Demography (from Ancient Greek δῆμος (dêmos) 'people, society' and -γραφία (-graphía) 'writing, drawing, description') [1] is the statistical study of human populations: their size, composition (e.g., ethnic group, age), and how they change through the ...
The demographic transition strengthens economic growth process through three changes: a reduced dilution of capital and land stock, an increased investment in human capital, and an increased size of the labour force relative to the total population and changed age population distribution. [2]
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 ...
However, world population growth is unevenly distributed, with the total fertility rate ranging from the world's lowest of 0.8 in South Korea, [13] to the highest of 6.7 in Niger. [14] The United Nations estimated an annual population increase of 1.14% for the year of 2000. [15] The current world population growth is approximately 1.09%. [8]
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 ...
The numbers show total births minus total deaths per 1,000 population for the region for each time period. The first four columns show actual rate of natural increase. The remaining columns show projections using the medium fertility variant.
