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]
In 2010, the East's fertility rate (1.459) clearly exceeded that of the West (1.385), while Germany's overall TFR had risen to 1.393, the highest value since 1990, [20] [21] which was still far below the natural replacement rate of 2.1 and the birth rates seen under communism. In 2016, the TFR was 1.64 in the East and 1.60 in the West.
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]
The preterm birth rate among Black individuals increased annually from 11.12% in 2014 to 12.51% in 2021, followed by a decline to 12.34% in 2022. ... the preterm birth rate for White people ...
The lowest rates were observed in Latvia (1.31), Hungary and Portugal (both 1.32) and Germany (1.36). The increasing fertility rate has also been accompanied by an upward trend in the natural increase of the population which is due to the moderate increase of the crude birth rate that reached 10.9 births per 1000 inhabitants in 2008, an ...
This is likely due to the birth rate declining among people of color. For example, between 1990 and 2010, the birth rate declined 29% among Blacks, 25 percent among Asians, 21% among Hispanics, but only 5% among White people. [55] If this trend continues the White birth rate will surpass the Black birth rate in a few years.
The mean age at childbearing indicates the age of a woman at their childbearing events, if women were subject throughout their lives to the age-specific fertility rates observed in that given year. [1] In countries with very high fertility rates women can have their first child at a much younger age than the mean age at childbearing.
In 2017, the U.S. birth rate remains well below the replacement level needed – at least 2.1 children per woman so as not to experience population decreases – as white American births fell in all 50 states and the District of Columbia. Among non-Hispanic white women, no states had a fertility rate above the replacement level.
