Query demographic data

Learn how to query demographic information for locations around the world with the GeoEnrichment service.

The GeoEnrichment service provides information such as population and household size about geographic areas that you define. The enrich method provides the ability to get facts about a location or area. Using Enrich, you can get information about the people, places, and businesses in a specific area or within a certain distance of a point.

In this tutorial, you use ArcGIS REST JS to access the GeoEnrichment service to search for demographic data within one mile of a clicked point and display the data in a overlay panel.

Prerequisites

You need an ArcGIS account to access the developer dashboard and create an API key.

Steps

Create a new pen

To get started, either complete the Display a map tutorial or .

Set the API key

To access location services, you need an API key or OAuth 2.0 access token.

Go to your dashboard to get an API key. The API key must be scoped to access the services used in this tutorial.

In CodePen, update apiKey to use your key.

Change line
//

const apiKey = "YOUR_API_KEY";
const basemapEnum = "ArcGIS:Streets";
const map = new mapboxgl.Map({
  container: "map", // the id of the div element
  style: `https://basemaps-api.arcgis.com/arcgis/rest/services/styles/${basemapEnum}?type=style&token=${apiKey}`,
  zoom: 12, // starting zoom
  center: [-118.805, 34.027] // starting location [longitude, latitude]
});

Update the map position

The GeoEnrichment service has data sources for many countries around the world, including most of Europe. Change the position of the map to center on eastern Europe.

Update the center parameter to [18.88, 47.33] and set zoom to 5.

Add a click event handler

You need a location before calling the GeoEnrichment service. To get a location, you can add a handler to the Map's click event. The click handler will be called with an object containing a LngLat.

You can change the mouse cursor to a crosshair to make it easier to click precisely. Use map.getCanvas to get the canvas, then modify its style property.

After the map initialization code, set the mouse cursor style to crosshair.

Execute the query

You pass one or more study areas to arcgisRest.queryDemographicData to specify the location of your query. To query a circular buffer around a point, pass a geometry object with x and y parameters. The default search radius is one mile.

Create a new arcgisRest.ApiKey to access the feature service.

Inside the click handler, call arcgisRest.queryDemographicData. Pass an array containing a single geometry object made from the event's lngLat property. Also pass the authentication object.

queryDemographicData is an asynchronous function. Using await, and declaring the click handler async, means the rest of the click handler will wait for the response before continuing.

Show a pop-up

If the query is successful, the response will contain a results array with a value containing a FeatureSet. The FeatureSet contains attributes such as population within the study area, the number of males and females, and the average household size. A message will display if there is no data available for a location selected. See the ArcGIS REST API documentation for more details.

You can use a pop-up to show the results of the query at the location where you clicked on the map.

To add a pop-up to the map, you use the Popup class in Mapbox GL JS. See the Display a pop-up tutorial for more information.

Set a variable containing the contents of the pop-up, using values from the query response.
