We have worked with Westminster City Council on a variety of face to face resident and engagement projects over the last seven years, including opinion tracking, service and campaign evaluation. An example of one of these projects can be found below​
 

• Each year, we have conducted 2,500 face to face in home interviews, with 125 interviews completed in each of the 20 wards. We employ a stratified random location quota sampling whereby sampling points are randomly selected with probability proportionate to their size (number of adults 16+) within each ward.

​

• Our sampling points are based on data from the latest Census Output Areas and we use the Bluewave Wealth map to ensure our final sample is representative in terms of affluence (particularly pertinent to Westminster).
