The OECD household survey was implemented using the internet, a cost-effective and promising approach to large-scale data collection.1 A survey provider (Lightspeed Research) was identified to collect responses to the questionnaire using its on-line consumer panels in different countries. The OECD chose the survey provider with care in order to minimise problems that can be associated with online surveys, such as biased samples, professional respondents and superficial responses. Thus, the survey provider’s panel size, recruitment, management and representiveness were scrutinised. In particular, the rules applied to manage the panel – such as the incentive mode used for the respondent and the maximum number of surveys a panellist can respond to per year – have been carefully examined.
