We explain to you what is the birth rate, what are its characteristics in the underdeveloped countries and the benefits in the more developed countries.
Birth is the number of births that occur in a population in a given period of time (usually annual periods). The birth rate allows you to calculate fertility levels.
The birth rate is calculated using a formula: number of births registered in “x time” per thousand inhabitants in relation to the entire population . It is a variable rate since births change according to regions or countries and according to times .
Certain moments in history can cause births to decline worldwide, as in large economic depressions, or they can also cause the number of births to explode. A clear example of this was after the end of World War II , this is the demographic phenomenon called the birth explosion .
When analyzing the birth rate, a wide variety of factors that influence it must be taken into account . The physical space and the period of time, as well as the cultural, religious, socio-economic, educational, nutritional and culturally more advanced areas influence the evolution of this rate.
In general, the rate increases progressively with respect to previous years, especially in underdeveloped countries, mainly due to cultural issues:
It is for these reasons that the increase in the birth rate is often explosive and uncontrollable year by year, thus causing the population to double every twenty years. Although in some countries, thanks to campaigns and operations in favor of birth control, fertility levels are being reduced.
In contrast to developed countries or the so-called “first world”, birth levels are lower, culture also has responsibility here. Thanks to its first world status, it has more benefits such as:
That is why nations such as Germany, Japan and Austria, find the lowest birth rates. The lowest birth rate is that of the Australian island Norfolk, which, in fact, is a negative rate.
