  2. Demography - Wikipedia

    en.wikipedia.org/wiki/Demography

    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 ...

  3. 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. Matrix population models - Wikipedia

    en.wikipedia.org/wiki/Matrix_population_models

    Matrix population models are a specific type of population model that uses matrix algebra. Population models are used in population ecology to model the dynamics of wildlife or human populations. Matrix algebra, in turn, is simply a form of algebraic shorthand for summarizing a larger number of often repetitious and tedious algebraic computations.

  6. 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. Euler–Lotka equation - Wikipedia

    en.wikipedia.org/wiki/Euler–Lotka_equation

    In the study of age-structured population growth, probably one of the most important equations is the Euler–Lotka equation.Based on the age demographic of females in the population and female births (since in many cases it is the females that are more limited in the ability to reproduce), this equation allows for an estimation of how a population is growing.
