Question
In the country of Kong, if the birth rate is 22 and the death rate is 9, what is the annual rate of natural population change? Is this high or low? Explain. In how many years will the population double if the growth rate stays constant, and migration is not a factor? Is that high, low, or medium? Explain. The total fertility rate of Kong is 2.5. Is that high, low, or medium? Explain. Suppose you knew the age structure of the country, especially the percentage of people under the age of 15. Of what use is that information??
Explanation / Answer
Given birth rate= 22
death rate=9
Annual rate of natural population change= Birth rate- death rate/10
=22-9/10=1.3%
Since the growth rate of natural increase of population is 1.3% so it is low.
Doubling time( in years)=70/r
r= rate of population growth=1.3%
Now Doubling time of population growth=70/1.3=53.8=54 years
Therefore population will double in 54 years
Since the lowest low fertility rate is defined as at or below 1.3 and it is given that the total fertility rate of the country is 2.5 which is medium.
