What does birthrate mean?
Birthrate is a noun referring to the number of live births in a population during a given year, conventionally expressed as births per thousand people. It is one of the most fundamental measures in demography, alongside death rate, migration, and life expectancy, and it offers a quick snapshot of whether a population is growing, stable, or shrinking. The term carries a neutral, statistical tone and appears frequently in news reporting on economics, healthcare, and social policy: governments track birthrates to plan schools, pensions, and labor markets, while economists watch them as signals of future growth. A falling birthrate often prompts debate about childcare costs, housing, and family support, while a high one may strain resources or signal rapid expansion. Closely related but distinct is the 'fertility rate,' which measures births relative to women of childbearing age rather than the whole population — a distinction worth keeping in mind when reading demographic statistics.
nounThe number of live births per year for every thousand people in a population, used as a standard measure of fertility and demographic change.
- The ratio of live births in a year to the total population, usually expressed as births per thousand people.
"The country's birthrate has fallen steadily over the past three decades."
"Japan's birthrate has remained among the lowest in the developed world."
"Government policies introduced in the 2000s helped raise the national birthrate slightly."
Usually treated as uncountable when discussing a single population, but plural forms appear when comparing across regions or time periods.
"Birthrates vary widely between urban and rural areas."
In much of the world today, the birthrate has fallen below the level needed to replace each generation — a demographic shift with no precedent in recorded history.

Etymology of birthrate
Birthrate is a straightforward English compound formed from 'birth,' an Old English word (beran, 'to bear') of Germanic origin, and 'rate,' which entered Middle English from Old French and ultimately from medieval Latin rata. The compound emerged in English during the nineteenth century, when modern statistics and censuses made systematic measurement of populations possible. Its components tie it to a broad Germanic word family including birthday, birthplace, and stillbirth.
How birthrate is actually used
A neutral, statistical term common in journalism, demography, and public policy. It is typically written as one word ('birthrate') or two ('birth rate'), with no difference in meaning; both are widely accepted.
