== Happiness ==
{{SVersion|3.3}}
Each pop in an empire has a '''{{iconify|happiness}}''' rating. It ranges from 0% to 100% and has a base level of 50%. Happiness determines approval rating when combined with stratum {{iconify|political power}}, as well as the following effects:
* Each point of happiness above 50 adds {{green|+1%}} {{iconify|governing ethics attraction}} to free pops and {{green|+2%}} {{iconify|Authoritarian}} ethics attraction to slaves.
* Each point of happiness below 50 adds {{red|−1%}} {{iconify|governing ethics attraction}} to free pops and {{red|+10%}} {{iconify|Egalitarian}} ethics attraction to slaves.
* Each point of happiness above 50 gives each pop {{green|−0.02}} {{iconify|crime}}, up to {{green|0}} per pop at 100% happiness.
* Each point of Happiness below 50 gives each pop {{red|+0.02}} {{iconify|crime}}, up to {{red|+2}} per pop at 0% happiness.

Fortunately, there are many ways to improve happiness in an empire. Planetary {{iconify|edict}}s, [[civics]], {{iconify|living standards}}, [[Empire#Permanent modifiers|permanent modifiers]], {{iconify|planet modifier}}s, and {{icon|ruler leader}} [[Leader#Ruler traits|ruler traits]] can positively affect happiness. [[Events]] may have an impact on planetary or empire happiness for a limited time as well.

=== Approval rating ===
Pop approval rating is a measure of the population's support towards the empire. It is determined by the average {{iconify|happiness}} of each stratum, weighted by {{iconify|political power}}. Pops without happiness are treated as having 50% happiness.

Approval rating ranges from 0% to 100% and has a base level of 50%.
* Each point of approval rating above 50% adds {{green|+0.6}} {{iconify|stability}}, up to {{green|+30}} at 100% approval rating.
* Each point of approval rating below 50% adds {{red|−1}} {{iconify|stability}}, up to {{red|−50}} at 0% approval rating.
