# Obtain Demographic Information

This section describes how to obtain demographic information for detected faces.

TIP: You must first detect faces by setting up a face detection task. For information about how to do this, see Detect Faces.

To obtain demographic information for detected faces

1. Create a new configuration to send to Media Server with the `process` action, or open an existing configuration that you want to modify.

2. In the `[Session]` section, add a new analysis task by setting the `EngineN` parameter. You can give the task any name, for example:

       [Session]
       Engine0=Ingest
       Engine1=FaceDetect
       Engine2=FaceDemographics

3. Create a new configuration section to contain the task settings and set the following parameters:

   `Type` | The analysis engine to use. Set this parameter to `Demographics`.
   Input | The track that contains detected faces that you want to analyze. Providing you have sufficient computational resources, OpenText recommends setting this parameter to the `DataWithSource` output track from your face detection task. For example, if your face detection task is named `FaceDetect`, set this parameter to `FaceDetect.DataWithSource`. Alternatively, you can use the `ResultWithSource` track produced by your face detection task.

   For example:

       [FaceDemographics]
       Type=demographics
       Input=FaceDetect.DataWithSource

4. Save and close the configuration file. OpenText recommends that you save your configuration files in the location specified by the `ConfigDirectory` parameter.
