MEASURING WHAT MATTERS
The MSP Index
Maximum Sustainable Prosperity -- the geometric mean of five dimensions that guides every policy decision.
MEASURING WHAT MATTERS
Maximum Sustainable Prosperity -- the geometric mean of five dimensions that guides every policy decision.
MSP Composite Score -- Year 10
10-year trajectory: 61.5 to 72.5 (+17.9%)
The Framework
A weighted geometric mean ensures no single dimension can be sacrificed. If any sub-index approaches zero, the entire MSP approaches zero.
MSP = (E0.25 × T0.15 × W0.25 × S0.20 × G0.15)1/1.00
Median income, Gini-adjusted GDP, labor participation, business formation, net worth by age cohort.
R&D spending, patents, broadband access, STEM workforce, technology diffusion lag.
Healthy life expectancy, life satisfaction, mental health, education, childhood development.
Interpersonal trust, institutional confidence, civic participation, safety, inter-group cohesion.
GHG emissions, biodiversity, freshwater quality, soil health, circular economy ratio.
Progress Over Time
From 61.5 to 72.5, the MSP Index rose 17.9% across the first constitutional decade. Key milestones annotated.
Source: Bureau of Metrics (CBM). MSP scores computed quarterly from 25 component indicators across 5 dimensions. Year 4: Digital Rights Amendment ratified. Year 6: brief economic slowdown. Fastest-improving sub-index: Ecological Stability (+29.7%).

How It Works
Transparent, auditable, and resistant to gaming. The MSP is computed quarterly by the constitutionally independent Bureau of Metrics.
25 component indicators measured quarterly by the CBM using household surveys (n=25,000+), administrative data, and sensor networks. Sortition-selected staff ensure independence. Seasonal adjustment via X-13ARIMA-SEATS. Annual indicators interpolated using Chow-Lin temporal disaggregation.
200+ automated validation checks per release. All data published on the Open Data Ledger for citizen audit. International peer review every 5 years by the International Statistical Institute. Annual red team exercises. Any citizen may formally challenge a statistic under CBM Charter Section 7.4.
Constitutionally fixed weights are recalibrated only every 10 years. Changes require a 60% legislative supermajority plus CBM validation. Goalposts reviewed alongside weights with 60-day public consultation and 12 months of parallel publication (old and new).
Each component is normalized to 0-100 via min-max normalization with fixed goalposts. Sub-indices are weighted arithmetic means of components. MSP is the weighted geometric mean: MSP = (E0.25 × T0.15 × W0.25 × S0.20 × G0.15). Confidence intervals computed via Monte Carlo simulation (10,000 draws). Typical 95% CI: ±2.5 points.
