Technical Specifications: Births (thousands)

Indicator name
(English / Spanish)
Births (thousands)
Nacimientos (en miles)
Indicator ID Births_Est_Num_1000
Domain Sociodemographic
Subdomain Demographic
Definition

Average number of births in a specific year, for a given country, territory, or geographic area, generally estimated mid-year.

Unit Thousands
Measure Absolute number
Type of statistics Predicted
Purpose

The number of births allows to quantify the magnitude of births that occur in a specific country or geographic area during a specific period of time. It is used as a denominator to estimate key demographic indicators, such as the birth and fertility rates.

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.

Interpretation example

In country A there were 2,286,300 births during 2018.

Disaggregation  
Limitations

The international comparability of this indicator may be affected by the periodicity for population censuses and demographic surveys. Population censuses are generally carried out every 10 years. Surveys have a frequency that varies between different countries, and the sampling error can also influence comparability. The value of the indicator also depends on whether the coverage of the civil registry system is adequate (greater than 90%), whether births are registered in the system in a timely manner, the integrity of the national registry, and how newborns who die are registered during delivery or within 24 hours after birth.

Estimated figures may differ from the statistics of countries due to factors such as methodological differences, for example, to produce population estimates and projections.

Other factors that may influence are differences in the definitions of vital events, the coverage, and the tabulation procedures applied in each country.
