. A population shows the following annual data: 3% emigration 2% immigration 2% births 1% deaths Which of the following is the change in population at the end of the year?
A. 3% decrease
B. 2% increase
C. 1% decrease
D. No change
I think it is not change.
Correct.
I THINK IT IS NOT CHANGE
To determine the change in population at the end of the year, we need to consider the net effect of all the factors that contribute to population change.
In this case, the factors are:
- 3% emigration: People leaving the population.
- 2% immigration: People entering the population.
- 2% births: New individuals born within the population.
- 1% deaths: Individuals dying within the population.
To calculate the net change, we can subtract the percentage of the population that leaves (emigration and deaths) from the percentage of the population that enters (immigration and births).
Net Change = (Immigration + Births) - (Emigration + Deaths)
Net Change = (2% + 2%) - (3% + 1%)
Net Change = 4% - 4%
The net change in population is 0%. Therefore, there is no change in the population at the end of the year.
The correct option is D. No change.
