  2. Rate of natural increase - Wikipedia

    en.wikipedia.org/wiki/Rate_of_natural_increase

    Data unavailable. In Demography, 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]

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

    The natural increase rate in column three is calculated from the rounded values of columns one and two. 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.

  4. Demographic transition - Wikipedia

    en.wikipedia.org/wiki/Demographic_transition

    Demographic transition. In demography, demographic transition is a phenomenon and theory which refers to the historical shift from high birth rates and high death rates in societies with minimal technology, education (especially of women) and economic development, to low birth rates and low death rates in societies with advanced technology ...

  5. Carrying capacity - Wikipedia

    en.wikipedia.org/wiki/Carrying_capacity

    Carrying capacity. The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the environment 's maximal load, [clarification needed] which in population ...

  6. Population momentum - Wikipedia

    en.wikipedia.org/wiki/Population_momentum

    Population momentum is a consequence of the demographic transition. Population momentum explains why a population will continue to grow even if the fertility rate declines. Population momentum occurs because it is not only the number of children per woman that determine population growth, but also the number of women in reproductive age.

  7. Climate change - Wikipedia

    en.wikipedia.org/wiki/Climate_change

    An example of a trade-off is that increased use of air conditioning allows people to better cope with heat, but increases energy demand. Another trade-off example is that more compact urban development may reduce emissions from transport and construction, but may also increase the urban heat island effect, exposing people to heat-related health ...

  8. Physical geography - Wikipedia

    en.wikipedia.org/wiki/Physical_geography

    Environmental geography is a branch of geography that analyzes the spatial aspects of interactions between humans and the natural world. The branch bridges the divide between human and physical geography and thus requires an understanding of the dynamics of geology, meteorology, hydrology, biogeography, and geomorphology, as well as the ways in ...

  9. Demographic momentum - Wikipedia

    en.wikipedia.org/wiki/Demographic_momentum

    Demographic momentum. Demographic momentum is the tendency for growing populations to continue growing after a fertility decline because of their young age distribution. This is important because once this happens a country moves to a different stage in the demographic transition model .
