Explanation:
To calculate the total births for the year, we can use proportions.
First, let's calculate the number of births per 1,000 people:
Birth rate = 11 births per 1,000 people
So, for every 1,000 people, there are 11 births.
To find the total number of births, we can set up a proportion:
(11 births / 1,000 people) = (x births / 9,507,000 people)
To solve for x (the total number of births), we cross-multiply:
11 * 9,507,000 = 1,000 * x
104,577,000 = 1,000x
Dividing both sides by 1,000, we find:
x = 104,577 births
Therefore, the total number of births for the year is approximately 104,577.
Now let's calculate the total deaths for the year using the same method:
Death rate = 13.5 deaths per 1,000 people
So, for every 1,000 people, there are 13.5 deaths.
Setting up a proportion:
(13.5 deaths / 1,000 people) = (y deaths / 9,507,000 people)
Cross-multiplying:
13.5 * 9,507,000 = 1,000 * y
128,104,500 = 1,000y
Dividing both sides by 1,000:
y = 128,104 deaths
Therefore, the total number of deaths for the year is approximately 128,104.
To calculate the change in population, we subtract the total deaths from the total births:
Change in population = Total births - Total deaths
Change in population = 104,577 - 128,104
Change in population = -23,527
The negative sign indicates that the population decreased by 23,527.
Therefore, the change in population for the year is approximately -23,527.
