Happiness and Health

When working with a city, it is important to track the Happiness and Health values.
== Health ==
Health is tracked per city. Each population point reduces the Health by 5%. A number of buildings and Social Policies grant Health bonuses.
Hypothetically, anything below 100% health can cause a population point to die due to ill health. Practically, the chance is extremely low, and it is perfectly safe to risk values as low as 35% with no major death rates. However, it is also necessary to consider that an outbreak of Plague will reduce a city's health by 30% which may result in a sudden die-off of population.
== Happiness ==
Happiness works slightly differently. It is decreased by:
*Each person living in a city(about -4% per person)
*Each city in an Empire(initially -5% per city, diminishing value for later cities)
*The distance from the city to the capital(almost -2% per tile, can be reduced by Tribunal and Courthouse)
*A Nation that has more influence than your Nation
Happiness can be increased by:
*Assigning population to the Artist job(+8% per Artist), or Idle with Dionysus' "God of Idlers" Spell(Varying% per Idle)
*Buildings(Gardens, Theater, Circus, Zoo)
*Social Policies
*Colonies
*Coatlicue's "New Fire" Spell
*Trade Routes with the "Eye of Horus" Power
*The "Bliss" Power
*Garrisoned units with the "Valhalla" Power
=== Importance of Happiness ===
* Firstly, if Happiness drops to below 20%, there is an increasing chance of that city leaving your Empire by a Revolution. They will join the Barbarians unless one AI has a noticeable influence lead on that city, which will instead cause it to join the AI.
* Secondly, there is a bonus to production at high Happiness levels, and a penalty to production starting at 70%. As such, it is recommended that happiness is not allowed to drop below 50%, ideally 60%, due to the crippling effects of the penalties.
Due to the bonus and penalty from Happiness, optimized production may well involve additional Artists having a larger impact than the associated job.
