Query demographic data

In this tutorial, you find demographic information for a location by accessing the GeoEnrichment service. The GeoEnrichment service provides information such as population and household size about geographic areas that you define.

Prerequisites

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

Steps

Create a new pen

If you are using the CDN libraries, to get started.

Get an 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.

Make the request

You can copy and paste the code below, following the steps to make a request to the GeoEnrichment service.

Reference the ArcGIS REST JS libraries either through CDN, ES Modules, or Node JS.
Set the apiKey with the API key from your dashboard.
Define the parameters needed for the request.
Call the Geoenrichment service and handle the results.
