The population increase is from 86 to 102.

We notice that the increase is

102 - 86 = 16.

So, we can get the answer using the rule of three.

If 86 represents 100%, then which percentage would represents 102?

[tex]102 \times \frac{100 \%}{86} \approx 118.6 \%[/tex]

The percentage increase would be

118.6% - 100% = 18.6%

Therefore, the percentage change is 18.6%.
