You must be an organisation administrator to do this.
This is the second stage of the process in choosing which Demographics to display on an Area Layer. Note that you do not have to change which Demographics are displayed to change the order.
On the Set Demographic display order page, you will see a list of all the selected Demographics from the previous page. Any Demographics already pre-selected will be in the original display order with any newly-selected Demographics appearing beneath those.
To change the display order, simply click on a Demographic in the list and drag it to the required position. When you have set the order you want, move on to Step 2.
Click the Save button in the top-right to complete the process. You will then be returned to the Layer Summary page.
