Constructs
state_fragility_index
State Fragility Index
A composite measure of state weakness capturing effectiveness and legitimacy across security, political, economic, and social dimensions.
institutional_capacity
Institutional Capacity
Government effectiveness and bureaucratic quality — the ability of the state to formulate and implement policy. Operationalized via WGI Government Effectiveness score or CPIA. Low capacity amplifies all other fragility drivers.
economic_resilience
Economic Resilience
Capacity of a state economy to absorb and recover from shocks — measured by GDP volatility, fiscal space (debt-to-GDP), foreign reserves, and export diversification. Low resilience states are coup-prone and food-crisis-prone.
security_apparatus_strength
Security Apparatus Strength
Fragile States Index sub-indicator measuring internal security threats: state monopoly on force, politically motivated violence, arms proliferation, insurgency, and civil unrest. Higher values indicate greater security fragility.
legitimacy_deficit
Legitimacy Deficit
Fragile States Index sub-indicator: public confidence in state institutions, corruption perceptions, political participation restrictions, and regime contestation. States with large legitimacy deficits face elevated coup and revolution risk.
demographic_pressure
Demographic Pressure
Population-driven stress: youth bulge (15-29 age cohort > 20% of population), rapid urbanization, food/water scarcity per capita, and disease burden. Youth bulges are robustly associated with conflict onset (Urdal 2006).
refugee_displacement
Refugee & IDP Displacement
Total forcibly displaced population (refugees + internally displaced persons) as count or per capita. Both cause and consequence of state fragility — displacement strains host communities, creates governance vacuums, and indicates state failure to protect.
external_intervention_fragility
External Intervention
Degree of foreign involvement in state affairs — military intervention, peacekeeping presence, foreign aid dependency (ODA as % of GNI), and sanctions. High external intervention signals inability to self-govern and can entrench fragility.
group_grievance
Group Grievance
Fragile States Index sub-indicator: ethnic, religious, or communal tensions and violence, including historical atrocities and discrimination. Captures the mobilizable resentment that can be weaponized for conflict.
factionalized_elites
Factionalized Elites
Fragile States Index sub-indicator: elite competition, power-sharing breakdown, defections, and brinksmanship. Factionalized elites are a proximate trigger for coups, civil war, and state collapse.
public_services_decline
Public Services Decline
Deterioration in essential state services: health system capacity, education access, infrastructure maintenance, and social safety nets. Measured via FSI sub-indicator or composite of WDI health/education spending.
human_flight_brain_drain
Human Flight & Brain Drain
Emigration of educated/skilled population and economic displacement. FSI sub-indicator capturing the loss of human capital that further degrades state capacity and economic prospects.
Findings
The PITF global instability model achieves ~80% accuracy in forecasting state instability onset 2 years ahead using only 4 variables: regime type (partial autocracy with factionalism), infant mortality rate, armed conflict in 4+ neighboring states, and state-led discrimination. Partial democracies with factionalism are the single strongest predictor.
Direction: positive
Confidence: strong
Method: Logistic regression, global country-year panel 1955-2003
Youth bulges (ages 15-24 exceeding 35% of adult population) significantly increase the risk of armed conflict onset, low-intensity conflict, and terrorism. A 1 percentage point increase in youth share raises conflict risk by ~7%. Effect is strongest in low-income countries with limited economic opportunities.
Direction: positive
Confidence: strong
Method: Negative binomial regression, country-year panel 1950-2000
Infant mortality rate (a proxy for state capacity and development) is the second strongest predictor in the PITF model after regime type. Countries with infant mortality above the global median face ~2.5x higher instability risk, reflecting the deep link between public health capacity and state resilience.
Direction: positive
Confidence: strong
Method: Logistic regression, global country-year panel 1955-2003
The concept of 'failed states' is analytically misleading — states rarely fail across all dimensions simultaneously. Call proposes distinguishing between 'collapsed states' (no central authority), 'weak states' (low capacity but functional), and 'war-torn states' (conflict-degraded). Most so-called failed states retain significant institutional capacity in some domains.
Direction: conditional
Confidence: moderate
Method: Conceptual analysis, comparative case studies
State fragility shows strong path dependence: countries in the 'Alert' category (FSI > 90) have a >80% probability of remaining in that category the following year. Escape from deep fragility requires sustained multi-dimensional improvement. The average time to move from Alert to Warning category is ~15 years.
Direction: positive
Confidence: moderate
Method: Longitudinal tracking of FSI scores 2006-2024
