Birth rate, also known as natality, is the total number of live human births per 1,000 population for a given period divided by the length of the period in years. [1] The number of live births is normally taken from a universal registration system for births; population counts from a census, and estimation through specialized demographic ...
Birth rate and mortality rates can change rapidly due to disease epidemics, wars and other mass catastrophes, or advances in medicine and public health. The UN's first report in 1951 showed that during the period 1950–55 the crude birth rate was 36.9/1,000 population and the crude death rate was 19.1/1,000. By the period 2015–20 both ...
This is the highest birth rate in the UK in 40 years. [99] By contrast, the birth rate in Germany is only 8.3 per 1,000, which is so low that both the UK and France, which have significantly smaller populations, produced more births in 2010. [100] Birth rates also vary within the same geographic area, based on different demographic groups.
Crude mortality rate refers to the number of deaths over a given period divided by the person-years lived by the population over that period. It is usually expressed in units of deaths per 1,000 individuals per year. The list is based on CIA World Factbook 2023 estimates, unless indicated otherwise.
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]
In demography, demographic transition is a phenomenon and theory which refers to the historical shift from high birth rates and high death rates to low birth rates and low death rates, as societies attain more technology, education (especially of women) and economic development. [ 1 ] The demographic transition has occurred in most of the world ...
The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.86%, 0.78%, and 1.08% respectively. [31] The last 100 years have seen a massive fourfold increase in the population, due to medical advances, lower mortality rates, and an increase in agricultural productivity made possible by the Green Revolution.

A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...
