    The Demography of the World Population from 1950 to 2100. Data source: United Nations — World Population Prospects 2017.

  4. Demographics of France - Wikipedia

    en.wikipedia.org/wiki/Demographics_of_France

    The slow growth of France's population in the 19th century was reflected in the country's very low emigration rate. The French population only grew by 8.6% between 1871 and 1911, while Germany's grew by 60% and Britain's by 54%. [22] French concerns about the country's slow population growth began after its defeat in the Franco-Prussian War ...

  5. Rate of natural increase - Wikipedia

    en.wikipedia.org/wiki/Rate_of_natural_increase

    In demography and population dynamics, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. [1] It is typically expressed either as a number per 1,000 individuals in the population [2] or as a percentage. [3]

  7. Demographic statistics - Wikipedia

    en.wikipedia.org/wiki/Demographic_statistics

    Demographic statistics are measures of the characteristics of, or changes to, a population. Records of births, deaths, marriages, immigration and emigration and a regular census of population provide information that is key to making sound decisions about national policy. [1] [2] A useful summary of such data is the population pyramid. It ...

  8. Population dynamics - Wikipedia

    en.wikipedia.org/wiki/Population_dynamics

    The half-life of a population is the time taken for the population to decline to half its size. We can calculate the half-life of a geometric population using the equation: N t = λ t N 0 by exploiting our knowledge of the fact that the population (N) is half its size (0.5N) after a half-life. [20]

  9. Population projection - Wikipedia

    en.wikipedia.org/wiki/Population_projection

    A population projection, in the field of demography, is an estimate of a future population. It is usually based on current population estimates derived from the most recent census plus a projection of possible changes based on assumptions of future births, deaths, and any migration into or out of the region being studied.
