We explain what the birth rate is, what its characteristics are in underdeveloped countries and the benefits in more developed countries.
What is birth rate?
The birth rate is the number of births that occur in a population in a given period of weather (generally annual periods). The birth rate makes it possible 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. population. It is a variable rate since births change according to the regions or countries and according to the times.
Certain moments in the history they can cause births to decline globally, as in major economic depressions, or they can cause the number of births to explode. A clear example of this occurred after finishing the WWII, this is the demographic phenomenon called Baby boom.
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, socioeconomic, educational, nutritional conditions and the more culturally advanced areas influence the evolution of this rate.
Birth rate in underdeveloped countries
In general, the rate increases progressively compared to previous years, especially in underdeveloped countries, mainly due to cultural reasons:
- Many times the lack of attention to the birth rate has to do with political issues, lack of information or training for the citizens.
- The creation of large families thanks to the fact that many times more family members are needed to survive.
- Religious factors often influence, in some religions abortions or the contraceptive methods are prohibited.
- Culturally there is no distribution of marked time and they do not have a notion of work 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 bend every twenty years. Although in some countries, thanks to campaigns and operations in favor of birth control, fertility levels are being reduced.
Birth rate in developed countries
In contrast to developed countries or the so-called "first world", birth rates are lower, culture also has responsibility here. Thanks to its first-world status, it has a greater number of benefits such as:
- More complete sexual education than in underdeveloped countries.
- Family planning (Chinese government launches one-child policy, government fines families with more than one child). This planning idea Condition It is the responsibility of the total population, because excessive population growth would have consequences at an economic and / or territorial level.
- The time is divided between work 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 have the lowest birth rates. The lowest birth rate is that of the Australian Norfolk Island, which is, in fact, a negative rate.
