Two small studies were embedded into the 2006 Questionnaire Design and Experimental Research Survey (QDERS). Both of these studies pertained to testing different ways to collect and verify demographic data using a computerized data collection mode. These results can be applied to any demographic data collection including surveys or censuses.

The first study is an experiment focusing on how to confirm age, given a valid date of birth. The second study is an investigation exploring a real-time edit to fix problematic relationship data by verifying with the respondent seemingly misreported relationships.
