The table below shows annual population growth rate history and projections for various areas, countries, regions and sub-regions from various sources for various time periods. The right-most column shows a projection for the time period shown using the medium fertility variant. Preceding columns show actual history.
Crude birth rate refers to the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population. The article lists 233 countries and territories in crude birth rate. The first list is provided by Population Reference Bureau. [1]
This is a list of Oceanian countries and dependencies by population in Oceania, which includes Australasia, Melanesia, Micronesia and Polynesia. Projections are from the United Nations [ 1 ] and official figures are from the Pacific Community [ 2 ] and other official sources.
[clarification needed] The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population. [2] [3] When the crude death rate is subtracted from the crude birth rate (CBR), the result is the rate of natural increase (RNI). [4]
Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels, assuming that mortality rates remain constant and net migration is zero. [10] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [10]
Falling birth rates have put major global economies on the path toward "population collapse," according to a report from McKinsey Global Institute. By 2100, some counties could see their ...
Thus, the figures after the 1960 column show the percentage annual growth for the 1955-60 period; the figures after the 1980 column calculate the same value for 1975–80; and so on. The formulas used for the annual growth rates are the standard ones, used both by the United Nations Statistics Division and by National Census Offices worldwide.
All of these economies have fertility rates far below 2.1, the “replacement rate” which allows for a stable population. They haven’t reported a rate above 2.1 for years, if not decades.
