Happiness and Discontent

Happiness is a value tracked independently for each city. Cities gain or lose Happiness each year from various sources, and can also experience one-time increases or decreases. A lose of Happiness is called Discontent .

A new city starts with a Happiness Level of 0 and a half-filled bar (50/100). It usually loses Happiness each turn based on the Difficulty setting and other modifiers, decreasing this bar (with the change indicated in lighter purple).

When the Happiness bar empties (0/100), the city gains its first Discontent Level with a nearly full bar (/110) which will continue to decrease while the Happiness is negative. Each time a city loses enough Happiness (100 + 10*level), it gains a Discontent Level . Each Discontent Level increases city Maintenance and reduces Science by 5%. It also decreases the opinion of the city's family by 20.

When the city starts to gain Happiness instead, the Happiness bar increases (with the change indicated in darker purple) and its Discontent Level goes down until being again a Happiness Level 0, then gaining Happiness Levels at the same rate as for Discontent Levels (100 + 10*level). Happiness Levels increases city Growth and reduces city Maintenance by 5%.

A positive change of Happiness is indicated as positive Happiness (e.g. +60 ) while a negative change of Happiness is indicated as positive Discontent (e.g. +10 ).
