How are demographics calculated?

[Mr. T]

I don't remeber how many of the demographic indicators are calculated.

For instance how is disease calculated? literacy?
Do these caluculations change by age?

I am sure someone has a list they can just paste the demographics have been basically the same since civ1.

Thanks guys.

I think that productivity is the sumation of shield production of per turn accross your civ.

Approval Rating - Ratio of happy to unhappy people

GNP - Income based on trade and tax/luxury rates
Since it is based on the tax slider, it can't be your total commerce "production" (total income). It is the part of your total commerce income that goes to taxes instead of science or luxury. I don't know however if buildings and military upkeep is deducted or not to get the final sum.

Manufactured goods - Total number of shields

Family size - Based on average food surplus

Military Service - Number of military units in relation to population

Productivity - Shields per total squares inside your borders (in civ2 it was shields minus support per square in use so I guessed that now it must be squares inside your borders)

I think this was on this site somewhere and I saved it.

What about the average lifespan of your citizens? I remember seeing this on the end game screen.
