Technical Specifications: Crude birth rate (1 000 pop.)
(English / Spanish)
|Crude birth rate (1 000 pop.)
Tasa bruta de natalidad (1 000 habs.)
The quotient between the number of births in a population over a given period and the total population over that period.
|Unit||Per 1 000 pop.|
|Type of statistics||Corrected/Predicted|
This indicator has application in the planning, implementation, development and evaluation of public policies related to maternal and childcare. It allows evaluating the effect of the implementation of strategies related to birth control or incentives. It is also used for the distribution of human, economic and technological resources necessary for perinatal health programs.
The crude birth rate is an indicator of population growth. Together with the crude mortality rate, they allow the evaluation of the level of population aging and estimation of its natural or vegetative growth.
If standardized based on a reference population, it allows the evaluation and comparison of temporal and geographical trends of the birth rate between different countries or within the same country over time. It also has applicability for making health care-related projections.
|Method of estimation||
For countries with a population greater than 90 thousand inhabitants, the figures are estimates from the United Nations, based on data that represent values estimated as of July 1st, obtained by linear interpolation of the corresponding five-year population projections of the United Nations, using the medium-variant projections.
For countries with less than 90 thousand inhabitants, the figures are estimates from the US Census Bureau International Database. The US Census Bureau population projections are based on the cohort component method.
The crude birth rate of country A for the five-year period 2015-2020 was 19.9 per 1 000 inhabitants and in country B it was 40.0 per 1 000 inhabitants., During this period, country A had 19.9 live births per 1 000 inhabitants, half of the births in neighboring country B.
The international comparability of this indicator may be limited due to factors such as the quality of population censuses and demographic surveys on the basis of which these calculations are made, among these factors are the misinterpretation of questions or memory bias. Estimating the birth rate requires a national civil registration system with adequate coverage (greater than 90%) and the timely registration of births.
Estimated figures of this indicator may differ from the statistics made by countries due to factors such as methodological differences, for example, to produce population estimates and projections.
Figures may be affected by variations in the sex and age structure of the study population. Because the confounding effect of age persists in this indicator, its value should not be used to make comparisons between different populations or in the same population over time.
The crude birth rate includes births, which are only one component of changes in a population, so it should not be confused with the growth rate that considers all components of change (births, deaths, and migratory movements).
It should not be compared with the fertility rate because the latter is not affected by variations in the age structure of the population and, furthermore, it considers women in its denominator.
