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]
Rates are the average annual number of births or deaths during a year per 1,000 persons; these are also known as crude birth or death rates. Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four ...
Conversely, other countries have policies to reduce the birth rate (for example, China's one-child policy which was in effect from 1978 to 2015). Policies to increase the crude birth rate are known as pro-natalist policies, and policies to reduce the crude birth rate are known as anti-natalist policies.
Natality is shown as a crude birth rate or specific birth rate. Crude birth rate is used when calculating population size (number of births per 1000 population/year), whereas specific birth rate is used relative to a specific criterion such as age. By calculating specific birth rate, the results are seen in an age-specific schedule of births.
By 1970 Russia was firmly in stage four, with crude birth rates and crude death rates on the order of 15/1000 and 9/1000 respectively. Bizarrely, however, the birth rate entered a state of constant flux, repeatedly surpassing the 20/1000 as well as falling below 12/1000.
One long-term effect of a declining birth rate could be a slowing economy. As the population expands, the economy has a larger workforce, which produces more goods and services. The net result is ...
English: Crude birth rates of sovereign states plus Greenland, French Guiana, New Caledonia, and Puerto Rico. Birth rate should not be confused with the generally more useful total fertility rate, which adjusts figures to account for how many females of reproductive age there are.
