Overview
Data on live births are obtained from records maintained by the Registry of Births and Deaths. The data covers all live births occurring within Singapore and its territorial waters as registered under the prevailing Registration of Births and Deaths Act in force at the material time. Data on fertility rates and number of children born compiled by the Singapore Department of Statistics depict the fertility profile of Singapore’s resident population.
Our Data Explained
Glossary
Crude Birth Rate
Crude birth rate (CBR) refers to the number of live-births to the population in the year per thousand population.
Gross Reproduction Rate
Gross reproduction rate refers to the average number of daughters a woman would have over her lifetime, under the assumptions that (i) she experiences the age-specific fertility rates prevailing during the reference period and (ii) she survives to the end of her childbearing years.
Live-Births
Data refer to all live births occurring within Singapore and its territorial waters as registered under the prevailing Registration of Births and Deaths Act in force at the material time.
Net Reproduction Rate
Net reproduction rate (NRR) is a refinement of the Gross reproduction rate (GRR), and is a measure of replacement of population. It refers to the average number of daughters a woman would have over her lifetime, under the assumptions that she experiences (i) the age-specific fertility rate and (ii) the age-specific mortality rate prevailing during the reference period.
To achieve population replacement, the NRR should be at least 1.0. This means that on average, each woman gives birth to at least one daughter who survives to reproductive age, ensuring that the female population is replaced from one generation to the next.
Number of Children Born
Number of children born refers to all live-born children each woman aged 15 years and over has ever given birth to. It includes those children who are currently staying with her, those who have set up their own homes, and those who are no longer living.
Total Fertility Rate
Total fertility rate (TFR) refers to the average number of live-births each female would have during her reproductive years if she were subject to the prevailing age-specific fertility rates in the population in the given year.
Age-specific fertility rate refers to the number of live-births born to females of a specific age group, out of every thousand females in the same age group.
