Demographic Data
Zoom in and click on a city, or use the Search Widget to find a city, and you will see a popup with population data for a 1-mile radius buffer around the selected point.
This sample currently uses code from our GeoBlazor Pro extensions library.

About this sample
This GeoBlazor Pro sample, written in Blazor for .NET developers, demonstrates GeoEnrichment-style demographic queries from the ArcGIS Maps SDK for JavaScript exposed through GeoBlazor Pro's ArcGISRest service combined with the LocationService, GeometryEngine, and SearchWidget Razor components. The page shows a 2D navigation basemap initially centered on Milan, Italy. A SearchWidget pinned in the upper-right corner lets the user type a place name, and the user can also click any point on the map. On either action, the sample reverse-geocodes the location to a city name, draws a one-mile geodesic buffer polygon as a translucent overlay using GeometryEngine.GeodesicBuffer, calls ArcGISRest.QueryDemographicData to retrieve global demographic facts for that buffer, and opens a popup showing total population, male and female counts, and average household size. The sample is intended to demonstrate how to combine geocoding, buffering, and demographic enrichment into a single click-driven workflow.
