absolute change is determined by the absolute value of the subtraction of the number of refugees in both years:
absolute change = | 16.1 million - 8.7 million | = 7.4 million
Relative change is given by the quotient between final value and initial value, just as follow:
relative change = final value / initial value
= 16.1 million / 8.7 million
= 1.85
Hence, the absolute change is 7.4 million and relative change is of 1.85
