The debate on quality issues in web surveys is open and lively (see , i.e., the Web Survey Methodology site). Data quality is required to satisfy the user's needs. Improving the survey process quality is a precondition for obtaining product quality at acceptable cost. This article contributes to the debate focusing on the timeliness of web surveys. From our perspective the timeliness of data collection is mainly due to the timeliness of response from the members of the eligible population. We identify several steps in the web survey process and divide the final response rate into different components, one for each step. We model the survival of eligible respondents, finding out which participants come farthest in the process of a web survey. The analysis contributes to the efforts to explore the nonresponse process and to shorten the individual survey period length.
