| Undernourishment (PoU) | People or population share | people | modeled estimate | Annual model estimate / multi-year statistical framework | Global and country estimates | No, except where the profile states a same-source component rule | Not interchangeable with FIES, GRFC/IPC/CH, or child-wasting estimates. |
| Moderate or severe FIES | People or population share | people | period prevalence | Past 12 months / official reporting period | Global and country estimates | No, except where the profile states a same-source component rule | Broader experiential measure; not a count of chronically undernourished people. |
| Severe FIES | People or population share | people | period prevalence | Past 12 months / official reporting period | Country and territory records in the validated FIES profile | No, except where the profile states a same-source component rule | A subset of moderate-or-severe FIES; the Step 11B chart summarizes 125 records in prevalence bands. |
| IPC/CH Phase 3 or worse | People in covered crisis areas | people | classification-period population | Current or projected acute analysis period | Selected crisis countries and areas | No, except where the profile states a same-source component rule | The GRFC 2026 headline covers 47 analysed countries and territories, not the global population. |
| Wasting | Children under age five or prevalence | children | prevalence estimate | Survey/model reference year | Global and regional estimates | No, except where the profile states a same-source component rule | A child nutrition outcome, not a food-access or acute-crisis population measure. |
| Severe wasting | Children under age five or prevalence | children | prevalence estimate | Survey/model reference year | Global and regional estimates | No, except where the profile states a same-source component rule | A subset of total wasting. |
| Refugees globally | People | people | year-end stock | End-year stock | World | No, except where the profile states a same-source component rule | The 41.6 million headline is a rounded grouping of three components. |
| UNHCR-mandate refugees | People | people | year-end stock | End-year stock | World | No, except where the profile states a same-source component rule | Includes people in refugee-like situations. |
| Refugee-like situations | People | people | year-end stock | End-year stock | World | No, except where the profile states a same-source component rule | Subset of refugees under UNHCR mandate. |
| All-cause IDP stock | People | people | year-end stock | End-year stock | IDMC global estimate | No, except where the profile states a same-source component rule | A people stock at one point in time, not the number of displacement events during the year. |
| Conflict IDP stock | People | people | year-end stock | End-year stock | IDMC global estimate | No, except where the profile states a same-source component rule | Counts people remaining displaced, not repeated movements. |
| Disaster IDP stock | People | people | year-end stock | End-year stock | IDMC global estimate | No, except where the profile states a same-source component rule | Counts people remaining displaced, not temporary evacuations or repeated movements as events. |
| All internal displacement movements | Movements | events | annual flow | Annual flow | IDMC recorded countries and territories | No, except where the profile states a same-source component rule | A person may be counted more than once; some disaster movements may be temporary or pre-emptive. |
| Conflict displacement movements | Movements | events | annual flow | Annual flow | IDMC recorded countries and territories | No, except where the profile states a same-source component rule | One person can be counted more than once. |
| Disaster displacement movements | Movements | events | annual flow | Annual flow | IDMC recorded countries and territories | No, except where the profile states a same-source component rule | One person can be counted more than once; some movements may be temporary or pre-emptive. |
| Suspected dengue cases | Reported case events | events | annual flow | Annual surveillance period | Americas regional surveillance reporting universe | No | Surveillance counts depend on reporting and do not correct for under-ascertainment. |
| Confirmed dengue cases | Confirmed case events within reported suspected cases | events | annual flow | Annual surveillance period | Americas regional surveillance reporting universe | No | Confirmation practices and reporting can differ across settings. |
| Severe dengue cases | Severe case events within reported suspected cases | events | annual flow | Annual surveillance period | Americas regional surveillance reporting universe | No | Severity classification depends on surveillance definitions and reporting. |
| Dengue deaths | Reported deaths | people | annual flow | Annual surveillance period | Americas regional surveillance reporting universe | No | A death count is an outcome measure and should be interpreted separately from case counts. |
| Confirmed share | Ratio of two reported case counts | rate | period rate | Annual surveillance period | Americas regional surveillance reporting universe | No | Depends on surveillance confirmation practices and the suspected-case denominator. |
| Severe share | Ratio of severe case events to suspected case events | rate | period rate | Annual surveillance period | Americas regional surveillance reporting universe | No | Uses reported suspected cases as the denominator and does not adjust for under-ascertainment. |
| Case-fatality rate | Ratio of reported deaths to reported suspected cases | rate | period rate | Annual surveillance period | Americas regional surveillance reporting universe | No | Depends on both death reporting and the reported-case denominator. |
