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.
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] The second list is based on CIA World Factbook estimates for the year 2023. [2] Dependent territories and not fully recognized states might not be ranked.
To the right of each year column (except for the initial 1950 one), a percentage figure is shown, which gives the average annual growth for the previous five-year period. 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 ...
(2011) World population growth rates between 1950 and 2050. The world population growth rate peaked in 1963 at 2.2% per year and subsequently declined. [9] In 2017, the estimated annual growth rate was 1.1%. [28] The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.86%, 0.78%, and 1.08% respectively. [29]
[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]
This is a list of population milestones by country (and year first reached). Only existing countries are included, not former countries. Only existing countries are included, not former countries. 20 million milestone
This is a list of countries showing past fertility rate, ranging from 1950 to 2015 in five-year periods, as estimated by the 2017 revision of the World Population Prospects database by the United Nations Population Division. The fertility rate equals the expected number of children born per woman in her child-bearing years.
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. [8] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [8]
