Civic Stress Index
A structural monthly measure of societal stress in the United States — grounded in relative deprivation theory, institutional legitimacy research, and validated economic indicators.
This is an experiment. The Civic Stress Index may produce inconsistent results, counterintuitive outputs, or be fundamentally wrong. That is expected and intended. We are examining deep connections between structural conditions and civic stress — connections that are obscure both by design (institutions work to hide them) and by their very nature (they involve feedback loops, nonlinearities, and unmeasured confounds). The index will fail in ways that are instructive. When it does, we learn what we were missing.
What it measures
The Civic Stress Index is not a prediction of civil unrest. It measures the stress state of American society — the structural and operational conditions that, historically, correlate with elevated civic tension, protest activity, and institutional strain. High scores indicate conditions that research associates with increased unrest probability; they do not predict events.
It comprises two complementary instruments: the CSI (Civic Stress Index), a structural monthly measure using slow-moving economic, institutional, and social data; and the CSSI (Civic Supply Stress Index), an operational 12-hour instrument tracking real-time supply chain, fuel, food, and event signals.
Scale
CSI — Structural components
The structural CSI draws on four research-grounded components, each independently validated in conflict-prediction or economic-stress literature:
Perceived purchasing-power erosion: necessity-weighted CPI (food-at-home + energy + renters shelter, bottom-40% weights), real wage gap, fuel prices, U-6 unemployment, and consumer sentiment divergence from verified conditions. Grounded in Stantcheva (NBER w32300, 2024) and Fed FEDS Notes (April 2025).
Composite of government, congressional, judicial, and media trust (Gallup) alongside polarization measures (Pew affective polarization, DW-NOMINATE divergence). Functions as a multiplier on EPI stress — the same economic conditions produce different civic outcomes depending on institutional legitimacy.
Structural supply conditions: NY Fed GSCPI (27-variable PCA, validated 2021–23), ISM PMI sub-indices, and ATA Truck Tonnage. The GSCPI contributed ~60% of above-trend inflation 2021–2023; a 1-SD shock adds ~0.5pp PCE with a 4–8 week pass-through to household prices.
Long-run structural substrate: V-Dem US democratic health indicators, EIG Distressed Communities Index, and social capital proxies. Slow-moving but load-bearing — the same economic shock produces different civic outcomes on a fragmented vs. cohesive social substrate (PITF, Goldstone et al., PLOS ONE 2021).
CSSI — Operational components
The operational CSSI runs at 12-hour cadence using fast-moving data, with the structural CSI as a contextual amplifier:
EIA weekly retail gasoline + diesel prices, NY Fed GSCPI (monthly leading), BLS food-at-home CPI.
ACLED US geocoded protest/riot/violence event counts (weekly) + GDELT 2.0 media conflict-tone spike index (15-minute cadence).
ATA Truck Tonnage Index momentum + EIA Electric Power Monthly outage indicators. Infrastructure capacity as a civic stress signal.
Research foundation
Current status
The CSI is currently in methodology development. No live score is published yet — the instrument is being specified, tested for calibration against historical ground truth (ACLED + GDELT), and documented. The methodology laboratory below records the full specification process, including formulas that failed adversarial review and why.
