A rate plateau of over 13.0 persons per 1,000 population occurred for every year from 1946 to 1962. There has been a fall in the rate of natural increase since 1962 due to falling fertility . In 1971, the rate of natural increase was 12.7 persons per 1,000 population; a decade later it had fallen to 8.5.
The replacement fertility rate is 2.1 births per female for most developed countries (in the United Kingdom, for example), but can be as high as 3.5 in undeveloped countries because of higher mortality rates, especially child mortality. [9]
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 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.
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 ...
In 2015, the birth rate among teenage women in Australia was 11.9 births per 1,000 women. [12] The rate has fallen from 55.5 births per 1,000 women in 1971, probably due to ease of access to effective birth control, rather than any decrease in sexual activity. [13]
The total (crude) birth rate (which includes all births)—typically indicated as births per 1,000 population—is distinguished from a set of age-specific rates (the number of births per 1,000 persons, or more usually 1,000 females, in each age group). [5] The first known use of the term "birth rate" in English was in 1856. [6]
The country with the lowest birth rate is Japan at 7.64 births per 1000 people. Hong Kong, a Special Administrative Region of China, is at 7.42 births per 1000 people. As compared to the 1950s, birth rate was at 36 births per 1000 in the 1950s, [92] birth rate has declined by 16 births per 1000 people. In July 2011, the U.S. National Institutes ...
