Answer:619 individual / year
Explanation:
We will add up the birth and immigration(individual coming from outside)
and we will minus the death and emigration(individual going away)
Since, the year in question is only 1 . we will divide the change in population by 1.
Growth rate = (1000+72-108-345) / 1 = 619
