Demographic structure

Refugee flows, migration events, population crises, and labor events Filter with GET /api/v2/events?family=cameoplus&cameoplus_domain=DEMOGRAPHIC, or on a specific subcategory code below. Every code in this domain starts DE. Goldstein does not apply to this domain — see the domain index. How the metrics read in this domain. magnitude is an impact tier scaled to the affected population; systemic_importance asks what the displaced population depends on or destabilizes, named as a specific node

​

DE01

MASS DISPLACEMENT OR REFUGEE EVENT A discrete forced displacement event triggered by a specific incident: refugee crisis crossing a national border in significant numbers, mass IDP movement within a country due to violence or disaster, official UNHCR crisis declaration for a displacement situation, refugee camp overflow or acute crisis, repatriation or resettlement event at significant scale. Distinguish from background displacement flows by requiring a discrete triggering event or declaration. Scale thresholds (use these to calibrate the magnitude tier, not as hard exclusion cutoffs):

• 1,000+ newly displaced: significant displacement event — magnitude tier 2–3, and lower confidence if no official recognition
• 10,000+ newly displaced: major displacement crisis — magnitude tier 4–6
• 100,000+ newly displaced: mass displacement emergency — magnitude tier 7+; any UNHCR emergency declaration regardless of count

Also covers

• large refugee flow
• mass displacement
• camp crisis
• IDP surge
• POSITIVE EVENTS also codeable: major repatriation programs (confirmed return of significant displaced population), formal UNHCR resettlement agreement covering large numbers, successful peace-linked return movement.
• IDP vs. REFUGEE: both coded as DE01. IDPs are within-country; refugees cross borders. Distinguish in notes and tags.
• HUMANITARIAN DECLARATIONS: when an international organization (UN OCHA, UNHCR, WFP) formally declares an emergency, code as DE01 or DE03 depending on whether the primary issue is displacement or food/water crisis.

​

DE02

MIGRATION EVENT A discrete migration policy implementation or major border movement event: large-scale border surge (tens of thousands crossing in a short period), mass deportation event (formal expulsion of significant numbers), entry ban or border closure affecting a major migrant route (implemented, not proposed), migrant/asylum-seeker policy enacted with immediate mass effect. Focused on the actual movement or enforcement, not the policy debate. Also covers

• border surge
• mass migration
• deportation wave
• migration policy change
• DE02 (border surge): large-scale unauthorized or asylum-seeking crossings in a short period — tag “border surge”
• DE02 (deportation): government-organized mass expulsion of migrants/asylum seekers — tag “mass deportation”
• DE02 (border closure): implemented closure of a major crossing point or migration route — tag “border closure”

Does not cover

• DEPORTATION EVENTS: a government carrying out mass deportations is DE02. A government THREATENING deportations is POLITICAL domain, code 13x (a threat is a speech act). Only code 174 (expel or deport) once deportations are ACTUALLY carried out.. The actual deportation/expulsion execution is DE02.

​

DE03

POPULATION CRISIS A discrete acute humanitarian crisis event: official famine declaration (IPC Phase 5 in a significant area), acute food insecurity emergency affecting millions (official UN/WFP declaration), water crisis reaching emergency threshold (city or region without access), mass casualty event from non-conflict causes (disease outbreak deaths at scale, industrial disaster), official humanitarian emergency declaration for population welfare. Threshold: UN or national government emergency declaration for acute need. Also covers

• acute famine
• food insecurity declaration
• water crisis
• mass casualty non-conflict
• HUMANITARIAN DECLARATIONS: when an international organization (UN OCHA, UNHCR, WFP) formally declares an emergency, code as DE01 or DE03 depending on whether the primary issue is displacement or food/water crisis.

Does not cover

• FAMINE vs. FOOD INSECURITY: DE03 covers discrete crisis declarations. Chronic food insecurity is background context. Code when WHO/UN/national government makes a formal declaration of famine (IPC Phase 5) or equivalent acute emergency.

​

DE04

LABOR EVENT A discrete large-scale labor action or disruption: general strike (national-level, multiple sectors), major sector-wide strike (national transport workers, national teachers, national healthcare workers), mass coordinated walkout with significant economic or service impact, major union bargaining collapse triggering national strike. Scale: national-level impact or involving hundreds of thousands of workers. Also covers

• mass strike
• general strike
• labor action
• major workforce disruption
• POSITIVE EVENTS also codeable: major labor agreement reached ending a significant strike or dispute (national wage agreement signed, landmark collective bargaining resolution), government labor market reform enacted with immediate effect on workers’ conditions.

Does not cover

• STRIKES vs. PROTESTS: labor strikes (work stoppages by employees) → DE04. Street protests and political demonstrations → ACLED (if violent) or POLITICAL domain (if non-violent). A strike that turns into a protest with clashes → ACLED primary, DE04 secondary.

​

DE05

URBANIZATION OR HOUSING EVENT A discrete event causing large-scale urban displacement or housing crisis: mass forced eviction affecting tens of thousands (government-ordered clearance, infrastructure project displacement), major informal settlement collapse or fire causing mass displacement, megacity infrastructure failure causing population emergency (water system collapse, sewage failure at city scale), significant housing market collapse with forced displacement consequences. Also covers

• megacity infrastructure failure
• housing collapse
• displacement from urban crisis
