Modifiers

Every named modifier in the game: what it changes, which way is better, and how many policies, technologies, focuses and traits grant it.

Modifiers from every source simply add up: two policies granting +2% and +3% economic growth give +5%. Most are applied as a percentage on top of a base rate; the monthly ones instead nudge a stored value such as stability up or down each month. All of them are recalculated once a month, or straight away when a source is gained or lost.
