Each indicator is normalized to 0-100. Higher = more late-cycle pressure. The composite CCI is a weighted average plus adjustments.
Spending (15% weight) - Total general government expenditure as % of GDP. Source: IMF WEO. Range: 10% (lean) to 60% (heavy state). Higher spending = further in the cycle.
Debt (12%) - Gross government debt as % of GDP. Source: IMF WEO. Range: 0-200%. Debt accumulation is how states finance extraction beyond revenue.
Growth (13%) - Average real GDP per capita growth over 5 years. Source: IMF WEO / World Bank. Inverted: low or negative growth signals extraction is suffocating the productive economy.
Migration (8%) - Net migration rate per 1000 population. Source: UN Population Division via World Bank. Inverted: people leaving is the most honest indicator - they vote with their feet.
Governance (25%) - Blended score: 30% WGI (World Bank - government effectiveness, corruption control, rule of law, regulatory quality) + 70% V-Dem Liberal Democracy Index (University of Gothenburg - executive constraints, civil liberties, judicial independence). WGI measures "does it function?" V-Dem measures "is it constrained?" V-Dem dominates because the cycle thesis is about unconstrained power. Efficient autocracies score high on WGI but low on V-Dem.
Fiscal Pressure (14%) - Interest payments as % of government revenue. Source: World Bank WDI. When interest consumes revenue, the state must tax more, borrow more, or print - the death spiral mechanism.
Demographic (13%) - Composite of fertility rate (below replacement = future worker shortage) and old-age dependency ratio (more retirees per worker = more fiscal pressure). Trajectory signal - affects the cycle in 20-30 years.
