Differbetween
The fertility rate is defined by the National Center for Health Statistics as the total number of live births per 1,000 women aged 15 to 44 years. ... Birth rates are different from fertility rates in that the denominator is not all women aged 15 to 44, but rather a specific age group.

Why is total fertility rate better than birth rate?
The TFR (or TPFR—total period fertility rate) is a better index of fertility than the crude birth rate (annual number of births per thousand population) because it is independent of the age structure of the population, but it is a poorer estimate of actual completed family size than the total cohort fertility rate, ...
What is the difference between crude birth rate and general fertility rate?
Crude birth rate (CBR) is the number of live births in a given year per 1,000 people alive at the middle of that year. General fertility rate (GFR) is the number of births in a year divided by the number of women of childbearing age (usually 15 to 49 years old, or sometimes 15 to 44 years old), times 1000.
What is 2.1 fertility rate?
Replacement-level fertility: Total fertility levels of about 2.1 children per woman. This value represents the average number of children a woman would need to have to reproduce herself by bearing a daughter who survives to childbearing age.
What's a birth rate?
The birth rate is the ratio between the number of live-born births in the year and the average total population of that year.
Which country has highest fertility rate?
In 2017, the fertility rate in Niger was estimated to be 6.49 children per woman. With a fertility rate of almost 7 children per woman, Niger is the country with the highest fertility rate in the world followed by Mali. The total population of Niger is growing at a fast pace.
Which country has lowest fertility rate?
All figures are estimates. In 2017, the fertility rate in Singapore was estimated to be at 0.83 children per woman, making it the lowest fertility rate worldwide. The fertility rate is the average number of children born per woman of child-bearing age in a country.
What is an example of total fertility rate?
Sometimes TFR is expressed per woman instead of per 1,000 women. For example, the theoretical replacement rate would be expressed as 2.1 live births per woman. Two variations in the five-year age groups used for calculating TFR are 15-49 and the formerly common 15-44 year age range.
What is general fertility rate formula?
Calculation:
(Number of resident live births / Number of females age 15-44 years) x 1,000. Number of Resident Live Births. X 1,000. Number of Females Age 15-44 Years Population.
How are fertility rates calculated?
The total fertility is expressed as the number of children per woman. Total fertility (TF) is computed as the sum of age-specific fertility rates weighted by the number of years in each age group, divided by 1,000. Where fa is the age-specific fertility rate for women whose age corresponds to the five-year age group a.
Are fertility rates declining?
In particular, the US has been reporting a steady decline in fertility rates for several decades now, with 2019 seeing a historic 35-year low in the number of births in the country. It is unclear how the ongoing coronavirus pandemic and public health crisis will affect these fertility rates.
What is a good fertility rate?
The single most important factor in population growth is the total fertility rate (TFR). If, on average, women give birth to 2.1 children and these children survive to the age of 15, any given woman will have replaced herself and her partner upon death. A TFR of 2.1 is known as the replacement rate.
What is fertility ratio?
By extension, the fertility rate is the ratio between the number of live births in a year and the whole female population of childbearing age (average number of women between 15 and 50 years of age over the year).
