Rate is called the coefficient that refers to the link between two magnitudes. Fertility, in turn, refers to fertility and the ability to produce or reproduce.
The idea of the fertility rate reveals the average number of births per woman that would exist if all women lived their entire fertility phase and gave birth according to the average fertility rate for each age. It is a variable that measures the possible scope of demographic changes in a territory. It is possible to differentiate between two classes of fertility rates: the general fertility rate and the total fertility rate. The general fertility rate is the index that reflects the number of live births registered in a year for every 1,000 women between 15 and 49 years of age. The global or world fertility rate, for its part, indicates the average number of births of women who completed the reproductive cycle in a given country.
Suppose that, in a year, 125 children are born in a village and there are 2,500 women of reproductive age (between 15 and 49 years). The general fertility rate, expressed per 1,000 women, is 50. In other words, we can determine that the formula to obtain the general fertility rate is the following: the total number of births in a country or region divided by the female population in reproductive age (15 to 49 years) and the result multiplied by 1,000. The total fertility rate, which is often simply called the fertility rate, indicates the average number of births that would occur in a year if all women in a region survived the fertile period and had children according to the fertility rate by age. This rate is falling globally in most industrialized countries. This fertility rate has become one of the basic demographic indicators to fully understand the reality of a country. However, we cannot ignore that, together with this, we resort to the study and realization of the realization and calculation of the other indicators mentioned. In the case of fertility itself, there are some such as the following:
-The fertility rate by age of the mother.
-The short-term fertility indicator.
-The average age of motherhood. In this case, we can say that to obtain this parameter, data such as the fertility rate or the aforementioned short-term fertility indicator must be used.
-The percentage of births by birth order.
-The percentage of births to single mothers. This refers to what single, widowed or divorced women are.
However, when it comes to knowing in depth certain sociological and social aspects of a nation, it is common to also resort to the analysis of what mortality is, through indicators such as the crude mortality rate, the mortality rate by age, which is done by sex or even life expectancy.
