What's the difference between an index and percentage growth/decline?

Example: Last year's volume was 158 vs 2006's volume of 97. If I
divide 158 / 97 I get 162.9. Isn't that the same as 62.9%? Why would I
use one over the other and if I decide I don't want it to read 162.9,
just 62.9, how do I get that to happen?

Thanks.
