Explanation / Answer
Given 4 countries birthrate and deathrates
Here, need to find the Net growth rate of country C for each year.
For year 1985:
Given Birthrate/1000=10.5
Deathrate/1000=11.9
Net growth rate can be obtained by subtracting deathrate from birthrate.
Net growthrate= Bithrate-Deathrate
=10.5 - 11.9
= -1.4
Here '-' sign shows that there is no growth of population.The population is declining.
For year 1995:
Given birthrate=11.2
deathrate=11.1
Net growthrate= 11.2-11.1
= 0.1
In this year, there is a growth of o.1
For year 2003:
Given Birthrate=12.5
Deathrate= 10.2
Net growthrate=12.5-10.2
= 2.3
There is much growth in the year 2003 which is 2.3
By observing the growth rates for the 3 years, the net growthrate is increasing i.e., The population is increasing.
Therefore, After next 20 years, the The country's population will increase.
Therefore, Net growth rate for 1985 is -1.4
Net growth arte for 1995 is 0.1
Net growth rate for 2003 is 2.3
And Best prediction for Country C future population is "The Country's population will increase"
Option C is the correct one.
