  2. Sub-replacement fertility - Wikipedia

    en.wikipedia.org/wiki/Sub-replacement_fertility

    In 2002, Australia introduced a Baby Bonus that did increase birth rates in the years immediately after. The fertility rate also increased to around 2.0 in France and 1.9 in Britain and some other northern European countries, but the role of population policies in these trends is debated. [51]

  3. Birth rate - Wikipedia

    en.wikipedia.org/wiki/Birth_rate

    The low birth rates in the contemporary United States can possibly be ascribed to the recession, which led families to postpone having children and fewer immigrants coming to the US. The current US birth rates are not high enough to maintain the size of the U.S. population, according to The Economist. [69] [70]

  4. Natality in population ecology - Wikipedia

    en.wikipedia.org/wiki/Natality_in_population_ecology

    Natality is the greatest influence on a population's increase. Natality is shown as a crude birth rate or specific birth rate. Crude birth rate is used when calculating population size (number of births per 1000 population/year), whereas specific birth rate is used relative to a specific criterion such as age. By calculating specific birth rate ...

  5. Population momentum - Wikipedia

    en.wikipedia.org/wiki/Population_momentum

    Population momentum impacts the immediate birth and death rates in the population that determine the natural rate of growth. However, for a population to have an absolute zero amount of natural growth, three things must occur. 1. Fertility rates must level off to the replacement rate (the net reproduction rate should be 1). If the fertility ...

    The Population Reference Bureau (PRB) ranking list is based on the data of the 2024 World Population Data Sheet [6] published online. The PRB [7] is a private, nonprofit organization which informs people around the world about population, health and the environment for research or academic purposes. It was founded in 1929.

  7. Total fertility rate - Wikipedia

    en.wikipedia.org/wiki/Total_fertility_rate

    A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...

  8. List of countries by rate of natural increase - Wikipedia

    en.wikipedia.org/wiki/List_of_countries_by_rate...

    Rates are the average annual number of births or deaths during a year per 1,000 persons; these are also known as crude birth or death rates. 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 ...

  9. Human population planning - Wikipedia

    en.wikipedia.org/wiki/Human_population_planning

    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 ...
