`worldpop_stats_polygon`

Pack: worldpop · Endpoint: https://gateway.pipeworx.io/worldpop/mcp

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/worldpop_stats_polygon for the schema, then POST the same URL with its arguments for the data.

Total population inside any polygon you draw, from WorldPop 100 m gridded population estimates (University of Southampton), for any year 2000-2020. Pass a GeoJSON Polygon or MultiPolygon in WGS84 and get the summed population count back. AUTHORITATIVE for “how many people live inside this boundary” at arbitrary geometry — a catchment, a flood extent, a service area, a proposed district — where census tables only answer for official administrative units. Keyless.

Parameters

Name	Type	Required	Description
`geojson`	object	yes	A GeoJSON geometry in WGS84 (lon, lat) — {“type”:“Polygon”,“coordinates”:[[[lon,lat],…]]} or a MultiPolygon. A Feature or FeatureCollection is unwrapped for you; the ring must be closed (first point repeated last).
`year`	number	no	Year of the population surface, 2000-2020 (default 2020).
`dataset`	string	no	WorldPop dataset id — “wpgppop” (population count, default) or “wpgpas” (age and sex structures). Call worldpop_datasets for the list.
`runasync`	boolean	no	Return the task id immediately instead of waiting for the result. Default false — the tool polls until the job finishes (about 3-10 seconds).
