Innovations in Rolling-Cross-Section Design: New Approaches to Analyze Voting Behavior

Christian Hoops and Dr. Alexander Glantz and Tobias Michael, Ipsos Public Affairs, in Journal of Political Science, 01/2014

By conducting our Ipsos Democracy Pulse we collected constant RCS-data so that not only all respondents but also the respondents for each day constitute random samples of the population. From this it follows that a sufficient number of hard-to-reach persons are included in the sample. Furthermore, the combination of landline and mobile phone samples increases the cardinality of the sample space.

This results in a higher degree of representativeness and a significantly better sampling quality. The structural equality of the RCS-design can be precisely quantified with an internal and external RCS-efficiency.
