We explain to you what is the birth rate, what are its characteristics in the underdeveloped countries and the benefits in the most developed countries.
What is birth?
Birth is the number of births that occur in a population in a given period of time (usually annual periods). The birth rate allows 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 globally, as in large economic depressions, or they can also cause the number of births to explode. A clear example of this came 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 should be taken into account . The physical space and the period of time, as well as the cultural, religious, socio-economic, educational, food and culturally more advanced areas influence the evolution of this rate .

Birth in underdeveloped countries
In general, the rate increases progressively compared to previous years, especially in underdeveloped countries, mainly due to cultural issues:
- Many times the lack of attention to birth has to do with political issues, lack of information or training for citizens.
- The creation of large families because many times more family members are needed to survive.
- Religious factors often influence, in some religions abortions or contraceptive methods are prohibited.
- Culturally there is no distribution of marked time and they do not have a notion of working time and educational time.
It is for these reasons that the increase in the birth rate is often explosive and uncontrollable year after 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.
Birth in developed countries
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:
- Sex education more complete than in underdeveloped countries.
- Family planning (the Chinese government launches a one-child policy, the government fines families with more than one child). This idea of state planning is the responsibility of the total population, because excessive population growth would have consequences at an economic and / or territorial level.
- Time is divided between working time and study time, to achieve a balanced life between professional life and people's private life.
That is why nations like 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.
