Answer:

0.023%

Explanation:

The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula

N/t where N is the total change in the population size, and t is time.

When immigration and emigration are factored in, we now have the formula;

(CBR +I) - (CDR + I)/1000

= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\
