Birth RateBirth rate is the number of live births per 1,000 persons in the population.
Age-Specific Birth Rates (Adolescent Birth Rates)An age-specific birth rate is the number of births to women in a certain age group per 1,000 women in that same age group (e.g., births to adolescent mothers per 1,000 adolescent girls of the same age in the population).
- Fertility Rate
Fertility RateFertility Rate: Live Births per 1,000 Female Population (Limit mother's age for age-specific fertility rate)
Age-Specific Fertility Rate: The number of live births to women in a certain age group, per 1,000 women in that age group. e.g., Live births to adolescent mothers per 1,000 adolescent girls of the same age in the population.
- General Fertility Rate
General Fertility RateThe general fertility rate is the number of live births per 1,000 females of childbearing age between the ages of 15-44 years. (The age range used can vary, depending on who is reporting the information. So it is important to note what age range is being used if you plan to compare these rates with those in other reports).
- Total Fertility Rate
Total Fertility RateThe total fertility rate is the sum of the age-specific birth rates of women in five-year age groups multiplied by five. This rate estimates the number of children a cohort of 1,000 women would bear if they all went through their childbearing years exposed to the same age-specific birth rates in effect for a particular time.
