/diseases/outbreaks/population

Returns the **reference list of outbreak populations** (human and animal host or cohort labels attached to outbreak records). Each item has **`population_code`** (numeric id), **`population`** (label), and **`is_human`** (`1` = human population, `0` = animal population). On **`GET /diseases/outbreaks/filter`**, pass **`population_code`** as **`population`** for the human population field, or as **`animalPopulation`** for the animal population field (the same ids appear in outbreak rows and in filter facets). For values already constrained by other outbreak filters, **`GET /diseases/outbreaks/filter-options`** returns overlapping options under `data.populations` / `data.animal_populations` (with `population_code` / `animal_population_code` respectively). #### **Query parameters** | Name | Required | Description | | --- | --- | --- | | `search` | No | If set, only rows whose **`population`** label starts with this string are returned (prefix match).
