We're just looking at a sample of the data so the actual per capital figures aren't meaningful. Yes they are. The per capita value is meaningful, albeit inaccurate, because you're estimating the value based upon a sample. Whatever number you multiplied every single index to get it into the range [0, 100], divide by that to get the per capita value.
