In my current game i was playing as Arabia and i took a look at the info screen (f9) which gives useful info like land area, population, commerce, goods produced, but i have no idea what the last three meant. It was something like approval rate, lifetime expectancy, and imports/exports. Im guessing approval rate and life exptectancy are happiness and health respectively. I think imports/exports are trade routes when you have open borders but why is it in the form of a fraction?
