What is general fertility rate in statistics?
What is general fertility rate in statistics?
The general fertility rate is an age/sex-specific birth rate while the total fertility rate is an age/sex-adjusted birth rate. The TFR is an age-adjusted rate because it is based on the assumption that there are the same number of women in each age group.
What is the general fertility rate formula?
GENERAL FERTILITY RATE 1. Definition: during a specified period (usually a calendar year) divided by the female population age 15-44 years (usually estimated for a mid-year) for that area, and the resulting fraction multiplied by a 1,000.
Why is general fertility rate important?
Tracking fertility rates allows for more efficient and beneficial planning and resource allocation within a particular region. If a country experiences unusually high sustained fertility rates, it may need to build additional schools or expand access to affordable child care.
What is the difference between crude birth rate and general fertility rate?
The general fertility rate (GFR) represents the annual number of births in a population per 1,000 women age 15-44. The crude birth rate (CBR) is the annual number of births in a population per 1,000 Page 2 44 | Fertility persons.
What is 2.1 fertility rate?
Assuming there are no migration flows and that mortality rates remain unchanged, a total fertility rate of 2.1 children per woman generates broad stability of population: it is also referred to as the “replacement fertility rate”, as it ensures replacement of the woman and her partner with another 0.1 children per …
How do you calculate total fertility rate and general fertility rate?
The TFR is usually simply described as the average number of children per woman which makes it an intuitive measure of fertility. The TFR is calculated by adding up all the age-specific fertility rates, multiplying this sum by five (the width of the age-group interval), and then dividing by 1,000.
Why is 2.1 the replacement fertility level?
What causes high fertility rates?
Factors generally associated with increased fertility include the intention to have children, in advanced societies very high gender equality, religiosity, inter-generational transmission of values, marriage and cohabitation, maternal and social support, rural residence, pro family government programs, low IQ and …
Why is NRR less than GRR?
NRR is always lower than GRR, because it takes into account the fact that some women will die before entering and completing their child-bearing years. Correspondingly NRR will be less than half the magnitude of the TFR.
Why GFR is more refined than CBR?
GENERAL FERTILITY RATE (GFR) It is also a cross-sectional measure of fertility. It is more refined than CBR as it includes only the population exposed to the risk of child bearing i.e, female population of the age group 15-49 years.
What is high fertility rate?
Age-specific fertility rate: Annual number of births per woman in a particular age group expressed per 1000 women in that age group. High fertility: Total fertility levels above 5 children per woman. Replacement-level fertility: Total fertility levels of about 2.1 children per woman.
What is low fertility rate?
The fertility rate – the average number of children a woman gives birth to – is falling. If the number falls below approximately 2.1, then the size of the population starts to fall.
