In recent literature on survey nonresponse, new indicators of the quality of the data collection have been proposed. These include indicators of balance and representativity (of the set of respondents) and distance (between respondents and nonrespondents), computed on available auxiliary variables. We use such indicators in conjunction with paradata from the Swedish CATI system to examine the inflow of data (as a function of the call attempt number) for the 2009 Swedish Living Conditions Survey (LCS). We then use the LCS 2009 data file to conduct several "experiments in retrospect". They consist in interventions, at suitable chosen points and driven by the prospects of improved balance and reduced distance. The survey estimates computed on the resulting final response set are likely to be less biased. Cost savings realized by fewer calls can be redirected to enhance quality of other aspects of the survey design.
