There's a couple of reasons why you might see 'no value' in a report or in place of a text token. It might mean that the data is missing from the original source, but let us know and we can check for you.
It might also be due to the areas you've selected; some areas, such as custom-built neighbourhoods, are composed of many small areas. In order to show data for custom-built areas, we aggregate the data from the component areas and depending on the type of area this might not occur. If you're seeing 'no value' results for custom areas, send us a quick email to let us know the problem and we'll get it checked.
