Users (including myself) search for a ward and confusingly cannot find it. I suggest that a warning is provided letting users know that the 2016 data does not contain wards. Also, there should be a link (including in the warning) that lets the user switch to 2016.
After discussing this we've determined the actual issue here was the response when using the search box taking too long, and a better user experience is required to show we're still awaiting a response.
