Birth rate- death rate= natural increase rate 20.97-7.48= 13.49 13.49 is the NIR
The rate of natural increase is the net gain in population when you subtract the Death Rate from the Birth Rate.
The formula for finding the rate of natural increase is as follows: (Crude birth rate - Crude Death Rate) / 10. The result is the rate of natural increase in percentage form. For example, Paraguay's crude birth rate (28.47) - the crude death rate (4.49) is 23.98; divide that by 10 and the result is 2.39%, Paraguay's rate of natural increase.
The rate of natural increase is the net gain in population when you subtract the Death Rate from the Birth Rate.
According to About.com, the natural increase in Germany is -0.2% and they have a zero rate of growth.
The formula to calculate the natural increase rate is (crude birth rate-crude death rate)/10 = % natural increase.
The second stage of demographic transition has the highest natural increase rate because there's a very low growth rate due to advances in medicine and sanitation technology, but families are still feeling like they need to have more children in case some die. In rural societies, families also see it as beneficial to have larger families to help farm.
Factors that are considered when determining a country's rate of natural increase include the birth rate, death rate, and net migration rate. The difference between the birth rate and death rate is a key indicator of natural increase, with higher birth rates and lower death rates leading to a higher natural increase. Net migration can also play a role in influencing the overall rate of natural increase in a country.
