Ideology
Part of the System outputs guide
Ideology is a resource your systems make for your empire. A system has no base ideology. All of it comes from buildings and other bonuses.

Where it goes
- Your empire gains the ideology of all your systems.
- Your dominions add a share of theirs. See Dominion Tax Rate.
What spends it
- Buying lexes and lex slots.
- Hiring Erased and Siderians.
- Liberate, Administer and Abandon. See Administrative Operations.
Buildings that produce ideology
Appeal Potential belongs to the body a building stands on. See Stellar bodies. Local Population counts only that body's population. Population counts the whole system. See housing.
