From Europa Universalis: Rome Wiki
There are four statistic abilities.
- Popularity: Popularity statistics represents the support a character has from the citizens and free men of the country, as well as from other characters.
- Loyalty: Loyalty statistics is a Character’s steadfastness in support of the state and/or the current Ruler and can also be seen as the reverse of a willingness to betray a Friend or Ruler.
- Prominence: Prominence statistics represents the amount of attention and fame a character enjoys.
Statistics range from 0 to 100 and changes more frequently than attributes.
