National Metrics

Last updated 2026-08-21

National metrics are the economic and social health indicators tracked for each country. They aggregate from state-level data each turn and are the primary scorecard for how well a country is performing. Bills, policies, corporate activity, and player actions all feed into these numbers.

The core national metrics#

GDP growth#

GDP growth measures the percentage change in total economic output. Corporate sector activity first produces a demand signal: owned sectors contribute their growth weighted by revenue, unowned sectors contribute a 0.5% background rate, and a 40% inertia smooths the sector signal.

The displayed national rate then runs through the output-gap model:

sectorSignal = smoothed revenue-weighted sector activity
impulse = sectorSignal - potentialGrowth
gdpGrowth = potentialGrowth + realizedChangeInBoundedOutputGap

The output gap closes over time, so a one-turn boom or contraction does not permanently reset the printed growth rate.

Unemployment#

Unemployment follows a simplified Okun's Law relationship with GDP growth relative to the country's potential growth:

Potential falls back to 2% only when the country has no seeded value. When macro labour effects are active, wage and automation shocks add pressure after Okun. Unemployment has an 85% inertia and hard bounds of 1% to 15%.

Inflation#

Inflation is recalculated every turn (not just annually), incorporating:

The target rate is 2.0%. Deviations trigger Chair infamy accumulation and affect all corporate margins.

State-level metrics#

GDP growth and unemployment are national aggregates. States also track many more granular metrics organized by category:

Economic metrics#

Education metrics#

Healthcare metrics#

Infrastructure metrics#

Public safety metrics#

Environment metrics#

Governance metrics#

Each metric has a value and a baseline. Policy effects push values away from baseline; natural decay (0.25% per turn toward baseline) slowly pulls them back.

How metrics change#

Policy effects#

Bills that pass into law apply ongoing effects to state metrics. For example:

Policy effects are applied each turn as long as the law remains enacted.

Corporate effects#

Corporations drive several metrics directly:

Additionally, per-sector margin modifiers mean that state conditions feed back into corporate decisions:

State metric Effect on corporate margins
Unemployment rate ±5% (pivot at 3%)
Power grid reliability −4% below 95% uptime
Corruption index −3% at max index
Road condition ±3% (pivot at 60)
Crime rate −5% (retail, real estate, entertainment)
Broadband access −4% (tech, telecom, media, financial)
Workforce skill ±4% (tech, healthcare, manufacturing, defense)

Natural decay#

All state metrics decay slowly toward their baseline at 0.25% of the current deviation per turn (proportional, not flat). A metric displaced 10 points from baseline returns to within 1 point after ~920 turns (roughly 19 game years). Sustained policy and corporate effects are needed to hold metrics away from baseline.

National aggregation turn#

Each turn, after state-level updates complete:

  1. State GDP growth rates are GDP-weighted into a national GDP growth figure
  2. Unemployment is updated via the Okun relationship
  3. Inflation is recalculated using current macro indicators
  4. National metric history snapshots are saved

What players can do#

As a legislator: Pass bills targeting specific state metrics. Subsidies for specific sectors, infrastructure spending, education funding: each enacted law leaves a permanent trace in the budget and the metrics it affects.

As a CEO: Grow your corporation's sectors to drive state GDP growth. High-growth sectors in a state improve the employment situation over time.

As a Central Bank Chair: Adjust the prime rate to manage inflation and indirectly support or constrain GDP growth. The Chair's effectiveness is measured against the 2.0% inflation and 2.0% GDP growth targets.

As Governor/President: Your approval rating is partly driven by economic conditions in your country or state. Strong GDP growth and low unemployment improve your standing; high inflation and unemployment hurt it.
