Economy

Every province produces output. Your tax level takes a share of it every week; administration takes a cut, and army upkeep is the biggest expense. A deficit drains the treasury and then builds debt, which costs interest. At war, upkeep rises by 20%.

Growth

Poorer economies catch up faster; stability and peace help, war, debt and unrest hold growth back. Capitals and big cities lead.

Bloc trade

Economic unions add a trade bonus to their members' output – see blocs.
