The population reproduction rate is one of the most important indicators characterizing the demographic situation in the country. It shows how many people are born on average per one death over a certain period of time.
However, this indicator may be distorted due to various factors such as migration, wars and other social processes. In order to obtain a more accurate estimate, it is necessary to clear the reproduction rate from these factors.
One method of purification is to use the net replacement rate method. This method allows you to take into account only those factors that directly affect fertility and mortality, such as the age structure of the population, level of education, availability of medical care and others.
The cleared population reproduction rate is calculated as the ratio of the number of births to the number of deaths over a certain period of time, but takes into account only those cases where both indicators refer to the same population group. This allows us to exclude the influence of various factors on the reproduction rate and obtain a more accurate picture of the demographic situation in the country.
In addition, the purified reproduction rate can be used to assess the effectiveness of programs to improve the demographic situation. For example, if the cleared replacement rate increases, this may indicate that the program to reduce mortality is working successfully and is leading to an increase in fertility.
In general, the refined population replacement rate is an important tool for analyzing the demographic situation and assessing the effectiveness of programs to improve it. It allows you to obtain more accurate data on fertility and mortality, as well as evaluate the effectiveness of programs to reduce mortality and increase the birth rate in the country.
