The average rate of population growth between 2010 and 2015 is 0.52 million people per year.
To find the average rate of population growth between 2010 and 2015, you can use the following formula:
Average Rate of Growth= Total Change in Population/ Total Change in Time
Let's denote P_1 as the population in 2010 and P_2 as the population in 2015.
Total Change in Population=P_2 −P_1
Total Change in Time=Year in 2015−Year in 2010
Substitute the values:
Total Change in Population=39.1−36.5
Total Change in Time=2015−2010
Now, calculate the average rate of growth:
Average Rate of Growth= 39.1−36.5/2015−2010
Average Rate of Growth= 2.6/5
Average Rate of Growth=0.52
So, the average rate of population growth between 2010 and 2015 is 0.52 million people per year.
